Web11/2024 External Combustion Sources 1.6-3 Methane emissions are highest during periods of low-temperature combustion or incomplete combustion, such as the start-up or shut-down cycle for boilers. Typically, conditions that favor formation of N 2 O also favor emissions of CH 4. 1.6.4 Controls WebCombustion process. The three main methods of calculation are: The "Calculate lambda" option determines the average air factor (lambda >= 1), based on the value of the end-of-combustion temperature set Tc. The "Calculate T" option determines Tc from the set lambda value. In both cases, the flow of the "fuel" process is adjusted so that the ...
