United States Environmental Protection Agency Air and Energy Engineering Research Laboratory Research Triangle Park NC 27711 Research and Development EPA/600/S8-88/007 Mar. 1988 Project Summary Industrial Combustion Emissions Model (Version 6.0) User's Manual Tim Hogan The full report is a user's manual for the Industrial Combustion Emissions (ICE) Model developed by the Environ- mental Protection Agency (EPA) for use by the National Acid Precipitation Assessment Program in preparing future assessments of industrial boiler emissions. The manual includes a summary of user options and software characteristics, a description of the input data files, and a description of the procedures for operation of the ICE Model. Proper formatting of files and creation of job control language are discussed. The ICE Model projects for each state the sulfur dioxide, sulfates, and nitro- gen oxides emissions from fossil fuel combustion in industrial boilers. Pro- jections of emissions and costs of boiler generation, including emission control costs, are projected for the years 1985, 199O, 1995. 2000, 2010, 2020, and 2030. In arriving at an emissions forecast, the model endogenously estimates the mix of coal, oil, and gas used in industrial boilers in response to projected fuel prices, emission stand- ards, and other factors affecting future costs of industrial boiler operation. This Project Summary was devel- oped by EPA's Air and Energy Engi- neering Research Laboratory, Research Triangle Park, NC, to announce key findings of the research project that is fully documented in a separate report of the same title (see Project Report ordering information at back). Introduction The ICE Model was developed by Engergy and Environmental Analysis, Inc. (EEA) to support EPA's analysis of acid deposition control alternatives. The ICE Model projects industrial fossil-fuel- fired boiler: • Fuel mix (natural gas, distillate and residual fuel oil, and coal) • Air emissions (sulfur oxides, sulfates, and nitrogen oxides) • Costs of boiler operation including emission controls by state for 1985, 1990, 1995, 2000, 2010, 2020, and 2030. Model Operation The ICE Model is a disaggregated process engineering model. Models of this type simulate the effects of specific policies on technical alternatives for new and existing equipment. The ICE Model is designed to assess the impact of several factors on industrial boiler fuel choice decisions and air emissions, including local and Federal air emissions regulations, fuel tenance (O&M) costs of firing alternative fuels or retrofitting pollution control equipment. The base year in Version 6.0 of the ICE Model is 1980. Industrial boilers existing in 1 980 are identified by size, annual capacity utilitzation rate, fuel type. State, industry group, and average air emission rates. The existing boilers may add or modify pollution control equipment or retrofit to burn another fuel type in response to proposed revisions in air emissions regulations or fuel price forecasts. Existing boilers are also retired over time. Model Inputs The input groups used by the ICE Model are shown in Figure 1. One major group ------- of inputs are the exogenously specified fossil fuel (i.e., coal, oil, and natural gas) prices for each of the years and states included in the projections. Also spec- ified are the total fossil fuel industrial boiler engergy demands by year, state, and industrial sector. New boiler fuel demand is determined by subtracting existing boiler fuel demand (net of retired boilers) from total fossil fuel demand. The expected new source performance standards (NSPS) for new boilers,in future years are a.lso inputted. These NSPS need not be the same for each year analyzed. The NSPS supplement a data base within the ICE Model of state environmental regulations. Each new boiler projected by ICE is sited in a State and Air Quality Control Region (AQCR), and the model determines the most restrictive standard applicable to each boiler. User's Manual The purpose of the ICE Model user's manual is to describe how the input data bases to the model can be altered by the user, how to properly implement emis- sion control alternatives within the model, and how to obtain output. Specific formats for data inputs and creation of job control language (JCL) are discussed. A complete run of the ICE Model for all years (i.e., 1985, 1990, 1995, 2000, 2010,2020, and 2030) requires 15 batch jobs or the linking of 15 jobs to one another in proper order for submission under one JCL file. Procedures for constructing the JCL file, and other necessary preparations to operate the model, are described. c Industrial Boiler Fuel Demand Forecast (Air Emission Standards ICE Model Industrial Fuel Price Forecast • Fuel Mix • Emissions • Costs Figure 1.
