METHOD FOR CONTROLLING AMOUNT OF NITROGEN OXIDES EXHAUSTED FROM GAS-TURBINE ENGINE

摘要

FIELD: pollution control of environment. SUBSTANCE: method for controlling NOx emission from gas-turbine engines of primarily ground and marine power plants involves combustion of rich and lean fuel-air mixtures in flame tube to form primary zone rich in fuel, lean-fuel burning zone and fast thinning zone for rich mixture combustion products between them. Steam or water mixed up with air is admitted to fast thinning zone for rich mixture combustion products. EFFECT: reduced emission of nitrogen oxides and reduced water flowrate. 2 cl, 3 dwg
