Reasons for Increasing Exhaust Gas Temperature of Boiler -

The heat loss of exhaust gas is the biggest one of all the heat losses of boiler. Generally the loss heat is 6% of the heat input into the boiler furnace. The heat loss of exhaust gas increases by 0.5% when the temperature of exhaust gas increases 12-15%.
