METHOD OF BURNING LIQUID AND GASEOUS FUELS

摘要

FIELD: heat-power engineering; boiler units or other fuel-consuming units where liquid and gaseous fuels are burnt together or separately. SUBSTANCE: burning of fuel is effected by means of four-orifice burners and automatic control system of fuel combustion; recirculation gases are fed in two flows at rated relationship. One recirculation flow is fed to root zone of flame core and other flow is fed to peripheral area of combustion zone. EFFECT: reduced effluents of nitric oxides with combustion products; enhanced efficiency of recirculation; reduced expenses for reduction of emissions of nitric oxides. 2 dwg
