To the user of this workbook
Unless otherwise infortoed, the answers you write in this book will
not count toward certification. However, this book will give you
information needed to pass the certification examination.
For further information about certification or additional directions
about how to use this book, please read the letter which came with the
book. If you are attending a training course, the instructor or
person-in-charge will be able to answer all your questions.
Introduction
This is a self--instructional workbook. Self-instructional means
you teaoh yourself. You read the information given about boilers and
incinerators. This information will be followed by questions about
what you have read. Always answer the questions. Always write your
answers in the book. (Always use a pencil.) The correct answers to
all questions are also given in the book. Always check your answers.
The answer to a question may be an explanation immediately following
the question. The answer may be at the bottom of the page. However,
most of the time the answer will be at the top of the next page. For
example, answer the following questions. If the answer is true, place
a check in the blank in front of true. If the answer is false, check
false.
1) The answer to some questions will come right after the
question in the book. True False.
2) The answer to some questions will be at the bottom of the
page. True False.
3) The answers to most of the questions will be at the top of
the jnext page. True False.
Now turn the page and look at the top of the page above the line.
n
-------
Answers: 1) True 2) True 3) True.
This is how most questions will be answered.
Now, please continue reading below.
NEVER LOOK AT THE ANSWERS GIVEN IN THE BOOK BEFORE YOU ANSWER THE
QUESTION YOURSELF. DO NOT JUST COPY THE CORRECT ANSWERS IN THE BLANKS.
IF YOU DO, YOU ARE NOT LEARNING. If you cannot answer a question or if
your answer was wrong, read the workbook again and then try to answer the
question again. Just remembering an answer that is given in the book
will not help you as much as understanding why the answer is correct.
If you do not understand the information in the workbook or if you
do not understand a question, talk it over with someone - many times this
will help. The city which provides this workbook will have someone in
charge of answering questions. If you received the book by mail, the
letter that came with it will tell you who you can contact for help. If
you are in a training class, ask the instructor-in-charge.
Take your time. There is no certain time in which you must complete
the workbook. The time needed will not be the same for each person. If
someone completes a workbook faster than you, do not worry about it. The
important thing is not how long it takes to complete the book but how
much you know when you are finished.
There are many different kinds of boilers and incinerators. The
workbook shows the basic things which are found on most kinds and types.
The equipment in the drawings may not be exactly like your equipment.
However, it will be close enough for you to follow.
Notice that some of the pages in this workbook have gray edges. These
pages are the HANDBOOK Sections and appear in both the boiler and the
incinerator parts of the book. You will complete the HANDBOOKS as you
go along. When you have finished the workbook, you will have made a
HANDBOOK for your exact boiler or incinerator. You can then quickly
refer to your HANDBOOK pages whenever you have a problem.
A final note...
As you qo through the book, you may find words that are unfamiliar.
A listing of subject related words may be found on pages 59-64, Glossary.
Good Luck

Section 1
THE BASICS OF PREVENTING
AIR POLLUTION EMISSIONS FROM BOILERS
including your own BOILER ROOM HANDBOOK
1. Choking
We've made a lot of progress toward cleaning up the air during the past few years, but we still have a
long way to go.
PUT A CHECK BESIDE THE THINGS BELOW THAT HAVE HAPPENED TO YOU.
Noticing that a thick gray cloud covers the city.
Being amazed at how clear the air seems to be in the country.
Finding that the metal work on the outside of your building is corroding due to pollution in
the air.
Taking a physical exam and wondering what pollution has done to your lungs.
Too many people are having experiences like these. Smoky boilers are part of the problem.
Please turn the page.
-------
2. Smoking
We don't mind smoke, unless:
a) there is too much smoke, or
b) the smoke is too black
When an inspector goes out to answer a complaint about smoke, he first finds out how black the
smoke is. Look at the four chimneys below. PUT "1" UNDER THE CHIMNEY THAT IS THE
LIGHTEST. PUT "2" UNDER THE NEXT LIGHTEST, ETC.
Check and correct
your answers
A=l, B=4, C2,D=3
DO YOUR NUMBERS MATCH THE NUMBERS ABOVE ?
If they don't,correct your answers on this page.
-------
3. Smoke Laws
Inspectors use the Ringelmann Chart to measure whether the smoke is dark enough to deserve a
summons. The darker the smoke, the more pollutants it contains. Study this chart.
RINGELMANN SMOKE READINGS
NEW YORK CITY LAW

Answer these questions:
1. How long can you have $£ 1 smoke coming out
of your stack without getting a summons?
2. Are you allowed to have £~ 2 smoke coming
out of your stack?
3. An inspector tells if smoke is illegal by how
dark it is and how long it's been coming out of
the stack.
(True or False)
Check your answers

not allowing dark smoke
allowing light gray smoke only a short time
CHECK OFF (/) THREE THINGS in the list below that are being done to cut down on pollution.
Low pollution oil is being delivered to your tank.
You are taking a training and certification lesson.
Your oil burning boiler will be taken out.
Your boiler should be upgraded to meet certain standards.

6. Ash and Smoke
Many things go up your stack. ASH and SMOKE are two of the main ones you can see.
POLLUTANT
ASH
SMOKE
WHAT IT'S ABOUT
Minerals in the oil that will not burn. Even the best oil
has a little.
Smoke small, floating carbon bits
oil is not burned completely. Good
this.
are produced when
operation can cure
Answer these questions:
1. Which pollutant must we always get, no matter
what we do?
2. Which pollutant is due to bad burning?
3. Which pollutant can we prevent completely?
Check answers
on the next page.
-------
Answers to Exercise 6: 1) Ash 2) Smoke 3) Smoke
7. Other Pollutants
Here are four more pollutants. Study the chart. Then ANSWER THE QUESTION IN THE LAST
COLUMN with "Yes" or "No". Remember that you can adjust your boiler to burn the oil
completely.
POLLUTANT
SOOT
SMUT
CARBON
MONOXIDE
NITROGEN
OXIDES
(large amounts)
WHAT IT'S ABOUT
Large pieces of carbon produced when oil is not fully
burned.
Soot and acid mixed together. If you stop soot, you stop
smut.
Formed when oil is not burned completely.
Formed when oil is burned at too high a temperature
with too much air.
COULD YOU STOP
ITV (yes or no)
You should have "Yes" in all four boxes in the last column. You can reduce or get rid of a[[ of these
pollutants if you operate your boiler correctly. ASH is the only pollutant you have to have.
CHECK THE CORRECT ANSWER BELOW:
The basic cause of the pollutants on this page is:
bad fuel
bad burning
Check answer
on the next page
10
-------
Answer to Exercise 7:
bad burning
8. Review
Check off the pollutants that you can prevent or reduce by good burning:
POLLUTANT
Ash
Smoke
Soot
Smut
Carbon Monoxide
Oxides of Nitrogen
(large amounts)
PREVENTABLE
Check and correct
your answers
You should have a checkmark next to every one except ash. All of these preventable pollutants are
due to bad burning.
Sulphur Oxides are the last pouutants. They are formed when the sulphur contained in oil is
burned. We take care of this problem by using fuel having a low sulphur content to start with.

9. Air/Oil Ratio
Here is the right way to burn oil.
1. What are the two things it takes to make a flame?
and
2. Does this "good flame" touch the furnace wall or floor at any point?
1. AIR, OIL
2. no
A correct mixture of air and oil will produce a good flame, which should fill the furnace without
touching its walls or floor. Too much air causes the flame to become too large. UNDER EACH
FLAME BELOW CIRCLE THE CORRECT ANSWER, "MUCH" or "LITTLE".
Flame Too Small
Flame Too Large
Too Much / Too Little Air
Too Much / Too Little Air,
Thin flames like the one at the left result from too little air. Too much air produces a flame that is
too big. Both kinds of flame produce smoke. Correct air/oil ratio is the name of the game when it
comes to beating pollution.
Answers 1. Too little
2. Too much

12. Draft Through The Furnace
There must be draft to pull air into the firebox, to help air mix with the flame, and draw hot gases
up the stack. Draft is very important for a good flame.
A damper in the chimney uptake controls draft. In small plants, this damper is operated by hand. In
plants burning 25 gallons per hour or more it is automatic.
Label the parts of the primary air, secondary air and draft systems on the diagram with the correct
letter from the list.

2 is correct...
-# 6 oil will burn only if it is sprayed into a fine mist. Most burners use a spinning cup to do this.
THIS IS WHAT HAPPENS IN YOUR BURNER:
Nozzle feeds oil into
cup.
Spinning cup picks up
oil stream.
When cup is
smooth - oil spins into a
fine mist.
Oil drops are sprayed
into the air coming
from primary air
around the cup - mixed
with air and burned.
Only tiny oil drops will burn completely. When the cup is damaged, the oil drops become larger.
What happens to an oversized oil blob in the firebox?

GRAY-EDGED pages are
Take this BOOK to your boiler room.
Get a pencil and a piece of chalk. As you follow the instructions given on each page, you will be
putting together a manual for running your boiler. It will contain lists of:
correct instrument readings and control settings
spare parts you should keep on hand
names and model numbers of parts of your boiler system to use when ordering parts or calling
service
fuel oil suppliers, service contractors and others whom you may need from time-to-time
These lists will be different for each boiler room. That's why only you can fill out your own
manual in your own boiler room. As you do it, make allowances for the fact that no two boiler
rooms are alike. Yours may be very different from the diagrams shown here. That's OK. The
important thing is to make sure you know where everything is and to get the information you
need to do your job right.
Remember...

SOME BASIC PARTS
Five major parts of a typical system are shown on this diagram. Using it for reference, take the
chalk and mark the following numbers on your boiler system (if you cannot find any part, skip it
and go on to the next one):
FIRST find the OIL PIPES:
Write a 1 anywhere on the oil supply pipe leading from the fuel tank to the heaters.
Write a 2 anywhere on the pipe leading from the electric heater to the burner.
NEXT find your OIL HEATERS:
Write a 3 on your Steam Heater or Hot Water Oil Heater
Write a 4 on your Electric Heater
NEXT you will mark the AIR delivering parts:
Write a 5 on your Primary Air Fan Casing.
Write a 6 on the Windbox (Secondary Air).

- WATER in the boiler
OIL hot enough to flow and burn properly
FUEL
You should check your fuel gauge every day, especially in winter. Keep a five-day supply on hand.
Draw a needle on the fuel gauge below showing a five-day supply of oil for you in winter (refer to
Boiler Handbook you've started).

If you have an automatic soot blower, this page will give you the basics. If you don't have one, turn
to the next exercise.
Blow your tubes during daylight hours, while the boiler is running, and about once every two
weeks.
Start the AIR COMPRESSOR and let it reach the 50 #- 100 # range. The SMOKE ALARM
should be turned off and the AIR CONTROL VALVE opened for the system to blow
automatically.
The smoke alarm is turned off because soot blown from the tubes would set it off when you don't
want it to.
Number these steps in the right order:
Start air compressor
Blow tubes (open air valve)
Turn smoke alarm off
Turn smoke alarm on
Shut off air compressor
Check and correct

TROUBLESHOOTING BOILERS;
FLAME READING
1. FLAME AWAY FROM THE BURNER
Most boilers have a peephole. Through it you can see the flame.
Look at this flame.
CIRCLE THE CORRECT ANSWER:
This flame is: A. too close to the burner.
B. too far away from the burner.
B is correct. The most likely reason is that the flame above is being pushed off the burner by
TOO MUCH PRIMARY AIR.
The PRIMARY AIR SHUTTER (regulated by LINKAGE) is taking in too much air. If you know how to set
the Primary Air Shutter, adjust it carefully. The correct air/oil ratio is the key to good flames and -
burning. If you don't know a lot about it, call service.

6. SCRUBBING THE GASES
New York City upgrading standards require all incinerators to have a SCRUBBER. As the garbage is burned
the EXHAUST GASES ARE CLEANED BY BEING WASHED VIGOROUSLY WITH WATER before going
out the Stack.
Here is a basic Scrubber diagram.

V- AUTOMATIC BY-PASS DAMPER
.--f- AUTOMATIC DRAFT CONTROL
Gases are moved by a FAN and controlled by a DAMPER and DRAFT CONTROL. Normally the
AUTOMATIC DRAFT CONTROL valve is left in the open position to allow the gases to pass into the scrubber
The purpose of the automatic draft control is to maintain a low uniform draft in the incinerator.
When the scrubber is temporarily shut down for cleaning or maintenance or an emergency such as water
failure, the AUTOMATIC BY-PASS DAMPER is adjusted so that gases are directed past the scrubber and up
the stack without being cleaned.
MATCH the devices with what they do:
Automatic By-Pass Damper
Automatic Draft Control

1. DAILY CLEANING
This section will cover tasks you should do each day to keep the system running smoothly
and maintenance tasks to be performed periodically. Also included are troubleshooting checks
to make before calling service should you get smoke.
Daily Cleaning reduces your chances of producing smoke. Your system will not work
smoothly if clogged with waste from burning.
Set a time each day to clean and check the incinerator. WAIT AT LEAST ONE HOUR after a
burn for the furnace to cool. SHUT DOWN THE SYSTEM by pushing the stop button. BELOW
ARE THREE PLACES to clean.
1. How long should you wait after a
burn to clean the incinerator?
2. From where would you clean cans,
bottles and other large waste mate-

4. DAILY CHECKS
In addition to cleaning, there are some DAILY CHECKS to make to keep major parts in good
working order.
CYCLING TIME CLOCK
ON THIS CLOCK, CIRCLE THE TIMES YOUR CLOCK IS SET to start a burn:
The clock is important as it brings together burning ingredients - garbage, air, ignition. If your
clock isn't working, call service to fix it.
Whom do you call for incinerator ser-
vice?
Do you have his number at a conven-
ient place for easy access?
Incinerator service agencies usually repair
all equipment.
What is the first daily check to make?
Check your answer.

JAMMED/WORKING
2.
Charging Gate apparently
JAMMED/WORKING
196
-------
The first incinerator has started to burn and is OK. The second is jammed in the open
position. It could also jam closed or partially open.
If the charging gate becomes jammed, check to see if GARBAGE is BLOCKING the gate or
track. If not, the ACTUATOR PISTON may not be working. It is usually operated by water
pressure. If your basic utilities (electric supply, city water pressure) are OK, call service.

212
-------
12. TROUBLESHOOTING
Even a well-run incinerator produces smoke or odors at times. If this happens, check four
things which may help you solve the problem. If not, call service.
FIRST - CHECK THE SCRUBBER
FAN
Does it sound like
it is running properly?
WATER MOVING
Is the System
functioning properly?
If waste gases aren't being pulled from the scrubber, the by-pass damper will automatically
open and that means smoke. The gases cannot be cleaned if the water isn't vigorously cleaning
them.
1. If you get smoke, what do you
check to see if the gases are being
cleaned properly?
2. What two things can you check in
the scrubber for proper operation?
213
-------
1. Scrubber
2. Fan
Water
If the Scrubber is OK, check the OVERFIRE AIR and the CHARGING FLUE GATE.
CHARGING FLUE GATE
Blocked by garbage
Actuator piston working?
OVERFIRE AIR ,
Blower operating?
The sound of the BLOWER generally tells you if it is operating properly. If the CHARGING
FLUE GATE is stuck, you may be able to remedy the situation without calling service.
214
-------
1. What could be stuck in an open or
closed position which may cause
smoke?
2. Which major air supply can cause
smoke if the blower is not working
properly?
3. What are three troubleshooting
checks to make in the incinerator
should you get smoke?
Check your answers.
-------
1. Charging flue gate
2. Overfire air
3. Scrubber
Charging flue gate
Overfire air
3.
The last troubleshooting check before calling service THE GAS BURNER. If the burner is
not running properly, smoke will probably result. A problem here generally means calling
service. You should check it out, however, as part of your information when calling service.
On the diagram below, LABEL THE FOUR TROUBLESHOOTING CHECKS to make before
calling service when you get incinerator smoke.
Check these with the list on
the following page.

PARTS-DEFINITIONS
HOPPER DOORS - Openings through which
tenants drop garbage.
CHARGING FLUE - Empty column that the
garbage falls through to the furnace.
CHARGING FLUE GATE - Gate across the
charging flue which collects the garbage. It
is opened and closed automatically by the
time clock.
OVERFIRE AIR - A fan and blower which
push air through a series of nozzles in a
pipe running into the furnace.
TEMPERATURE CONTROL - An automatic
control which turns the burner off/on to
maintain a 1400° 1600°F burn.
CYCLING TIME CLOCK- Device set to
activate various parts of the incineration
system at appropriate times.
GAS BURNER -14, Ignites the burn and
increases temperature if fire cools.
HEARTH - Steep incline which causes gar-
bage to form a pile for burning.
GRATE - Metal, louvered platform on which
garbage is burned.
FIRE DOOR - Door leading to the furnace.
UNDERFIRE AIR- Manually adjustable
louvers in the clean-out door which permit
air to pass in and up through the grate to
the burn.
CLEAN-OUT DOOR - Door to the ash pit.
AUTOMATIC BY-PASS DAMPER - Damper
which opens automatically when the scrub-
ber is off; draws flue gases past the
scrubber and out the flue.
AUTOMATIC DRAFT CONTROL- Regu-
lates furnace draft; draws flue gases into
the scrubber.
SCRUBBER - Device which cleans exhaust
gases by running them through a water
curtain before sending them out the flue.
WATER NOZZLES- Openings through
which the water is sprayed in the scrubber
to form a water curtain.
SETTLING TANK - Water tank at the base of
the scrubber.
SUMP - Outlet at base of settling tank where
residue taken from the gases settles.
STRAINER - Device in water pipe which fil-
ters out any residue in the discharge water
as it is recycled in the scrubber.
SCRUBBER FAN - Blower which takes the
clean flue gases from the scrubber and
directs them out the flue.
SPARK ARRESTOR - Wire screen cap over
the top of chimney which will catch any
large materials in the emission gases.'
PURGE DAMPER - Damper at top of charg-
ing flue on double flue inci nerator. Nor-
mally closed; opened to clean charging
