Combustion occurs during basic power generation operations where steam, electricity, and other forms of power are produced through the burning of basic fuels such as natural gas, oil, and coal.  When these fuels are burned many different compound emissions result in the exit gas stream from the power plant.  Combustion emissions also occur when generators, incinerators, and/or compressors are operated. 

 Emission Master and Emissions Accountant have teamed up to provide an easy way to characterize the emissions from each combustion operation in the plant site and then track the ongoing emissions as combustion records become available.  Emission Master provides the basic combustion model to the user where the user specifies the equipment, fuel combustion quantity, and time period.  Emission factors are entered directly or retrieved from the Emission Factors database.  Emission factors may be defined in a variety of ways in terms of the mass of pollutant generated per quantity of fuel consumed or time of operation.  Emission Master then calculates the combustion emissions from the basic model that has been created.  Emissions from the combustion operation are then exported and made ready to be pulled into Emissions Accountant. 

 Emissions Accountant enables the user to enter basic combustion operations that occur in the plant site whether they are boiler, generator, incinerator, compressor, or other operations.  Emissions calculated by Emission Master are imported and tagged to the designated process operation at the plant site.  Combustion records may then be entered for each device as the operation occurs.  Reports may be generated within Emissions Accountant that cover all combustion operations during the past twelve months or other time frames of interest.
