What are the reasons for the rising temperature of boiler exhaust gas?

29 Oct 2021
  1. Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
  2. The excessive air coefficient. Under normal circumstances, with the increase of excess air coefficient at furnace outlet, the temperature of boiler exhaust gas increases.
  3. Excessive air leakage coefficient. Air leakage refers to furnace air leakage and flue air leakage, which is one of the main reasons for the temperature rise of boiler exhaust gas.
  4. Feed water temperature is too high. The heat transfer temperature difference between flue gas temperature and water temperature is small, which makes the temperature of boiler exhaust gas rise correspondingly.
