An 11-month baseline-emissions survey tested 55 stationary reciprocating-piston engines (34 different models) and 11 gas turbines (9 models) in natural gas gathering and transmission lines at 23 different sites. The emission rates were calculated in lb/hr (mass rate, lb/million Btu heat input (fuel-specific), and g/hp-hr output (brake-specific). For the piston engines, the rated were determined at (or as near as possible to) the engine's rates speed and load, leading to some relative comparisons among the engines. The results showed that for the gas turbines, NO/sub x/ emissions were reduced by a decrease in the gas generator turbine speed; for the reciprocating engines, four factors decreased NO/sub x/: lower torque, higher scavenging-air pressure, retarded ignition timing, and cooler intake air.
