A detailed description of the scope of boiler delivery | Wellons.PRO

An air pre-heater is installed on the boiler exhaust in the direction of the gas flow to provide heat exchange between flue gases and combustion air (via pipes). It consists of 76 mm vertical tubes which allow to raise primary combustion air temperature to 200°C and cool the exhaust gas (to a temperature not lower than the dew point of ~ 160°C), increasing the overall efficiency of the system.

Exhaust Gases from Combustion and Industrial Processes

GAS TEMPERATURE The exhaust gas temperatures are fairly constant,and boilers and furnaces operate with stack gas temperatures of 285 to 590 F with a mean of 450 F (Table II-1.2). There is some indication that larger boiler units have hotter exhaust temperatures than small units.
