What are the main reasons for the increase in exhaust temperature of gas fired boiler?
Ash accumulation on the heated surface. Scaling and ash accumulation on the water-cooled wall of the furnace chamber and ash accumulation on the superheater, convection bundle, coal economizer and preheater increase the thermal resistance of the flue gas, weaken the heat transfer and reduce the cooling effect of the cooler. flue gas and increase the exhaust temperature of gas-fired boiler.
