FUNDAMENTALS OF COMBUSTION AND HEAT LOSSES

Heat loss with waste gases By reducing the temperature of waste gases by 22 degree cent it is possible to increase boiler efficiency by 1%. The exit temperature of waste gases depends on 21 feed water temperature at economizer inlet and and cold air temperature at air heater inlet. The exit temperature depends on the moisture

Boiler Efficiency - an overview | ScienceDirect Topics

The biggest heat loss from a steam generator is the heat lost with the exiting flue gas. The flue gas loss depends on the final flue gas temperature and the amount of flue gases. Thus the higher the air ratio, the higher the flue gas losses. The flue gases should leave the boiler at a temperature as low as possible to minimize the flue gas losses.

EC: Lesson 11. Scale and sludge formation in boilers

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

TYPE OF HEAT LOSS IN BOILER AND THEIR PREVENTION

Reducing excess air by 5% can increase boiler efficiency by 1%. Moisture free fuel should be fed to the boiler so that no amount of heat is lost in removing the moisture from fuel and all the heat can be efficiently used to convert water to steam. Most heat losses are due to the high temperature of dry flue gases leaving the boiler. Boiler maintenance should be done regularly …
