METHOD OF ENHANCING RELIABILITY OF OPERATION OF HEATING SURFACE OF BOILERS

摘要

FIELD: manufacture of steam generators. SUBSTANCE: temperature of metal of heating surface is reduced through reduction of temperature of combustible products due to incomplete combustion in furnace which takes place due to incomplete combustion of fuel at air excess coefficients ranging from 0.75 to 0.85 followed by after-burning of fuel before convective heating surfaces or due to injection of water or recirculation of combustion products to boiler furnace or by combination of all these methods. EFFECT: enhanced efficiency. 4 cl, 1 dwg
