Abstract:

For test cells, regional and state air pollution control agencies require that naval air installations obtain first, a permit to construct, and then a permit to operate. To apply for permits, personnel responsible for operating the test cells need to know the amounts of gaseous and particulate emissions formed during engine testing. This handbook shows how to estimate the gaseous emissions of carbon monoxide, oxides of nitrogen and hydro carbons formed during the operation of gas turbine engines. For each power setting of the engine, the estimation of total emissions needs 1 a ratio of the contaminant formed to the amount of fuel used the so-called emission index 2 the duration of the operation and 3 the fuel flow rate. Of these, the emission index is the most difficult to find. This handbook furnishes summary tables of representative emission indexes, at various power settings, for the gas turbine engines most likely to be operated at naval air installations. These tables also include fuel flow rates. Thus, anyone knowing the duration of the power settings can estimate the total gaseous emissions from various aircraft engines. The discussion of the emission index includes instructions on how to calculate it using both computers and small programmable calculators.
