METHOD OF AND SYSTEM FOR REDUCING INSTABILITY OF FUEL BURNING IN COMBUSTION CHAMBER IN OPERATION AND DEVICE TO SUPPLY GASEOUS FUEL (VERSIONS)

摘要

FIELD: mechanical engineering. SUBSTANCE: proposed device designed for use in system with gaseous fuel supply source and combustion chamber contains actuating mechanism, controller and mixer. Controller generates command characterizing the action to be exerted on actuating mechanism. Actuating mechanism receives gaseous fuel source and, according to command signal, forms gaseous fuel flow with modulated velocity of flow. Mixer receives modulated flow of gaseous fuel from actuating mechanism, mixes gaseous fuel with air and delivers fuel-air mixture into combustion chamber. Invention makes it possible to reduce instability of burning in combustion chamber, provide effective control of pressure fluctuation level in combustion chamber, create simple and reliable device providing control of level of instability of burning without confirmable rise of formation of NOx in combustion chamber. EFFECT: reduced instability of fuel burning in combustion chamber. 22 cl, 13 dwg
