| Abstract: | It discusses a boiler in a factory in Xinjiang with flue gas waste heat recovery system （LLHS） to reduce the technical route and energy saving effect of flue gas temperature, switching operation mode optimization principle thermal system parameters and pure condensing heating system. The addition of LLHS decreased after flue gas temperature of not less than 25 DEG C. Set annual power supply coal consumption reduced 2.56g/kWh （including the heating period）, each boiler saving 2270 tons of standard coal, 43700 tons of water saving, reduction of 24% net flue gas moisture content inside the chimney, to provide for the normal operation of desulfurization system guarantee. |
