Electric Infrared Incineration
Shirco Infrared Systems, Inc.
TECHNOLOGY DESCRIPTION: The electric infrared
incineration technology is a mobile thermal
processing system which uses electrically powered
silicon carbide rods to bring the organic waste to
combustion temperatures and then, to incinerate any
remaining combustibles in an afterburner. The mobile
system is comprised of four components: the
electric-powered infrared primary chamber, a gas-
fired secondary combustion chamber, an emission
control system, and a process management and
monitoring control center.
Waste is fed into the primary chamber on a wire
mesh conveyor belt and exposed (at temperatures of
up to 1850°F) to infrared radiant heat provided by the
horizontal rows of electrically-powered silicon
carbide rods above the belt (Figure 1). A blower
provides air at selected locations along the belt and
can be used to control the burning rate of the waste
feed and its location while burning on the belt.
The ash material which drops off the belt in the
primary chamber is quenched by water sprays
utilizing scrubber effluent. The ash is held until the
PCS content is determined to be less than 1 ppm.
Gaseous volatiles from the primary chamber are
destroyed in the fired secondary chamber. Gases are
ducted through the emissions control system, which
consists of a venturi scrubber for particulate matter
and a packed tower to neutralize acid vapor. An
induced draft blower draws the cleaned gases from
the scrubber into the free standing exhaust stack.
The scrubber liquid effluent then flows into a clarifier
where scrubber sludge settles out for disposal.
Finally, the scrubber effluent flows to an effluent tank,

through an activated carbon filter for reuse, or to a
POTW tank for disposal.
WASTE APPLICABILITY: This technology is suitable
for organic wastes contained in soils or sediments.
Liquid organic wastes can also be handled once they
are mixed with sand or soil.
DEMONSTRATION RESULTS: Demonstration of the
electric furnace was carried out at full-scale at an oil
refinery site near Tampa, Florida, from August 1 to 4,
1987. As part of the removal operation by EPA
