Reasons for High Air Preheater Exhaust Temperature

Reasons for High Air Preheater Exhaust Temperature Reasons for High Air Preheater Exhaust Temperature Because the exhaust temperature of air preheaters in power plant boilers is generally high, this high exhaust temperature reduces boiler efficiency, resulting in insufficient drying output in the pulverizing system, making long-term operation very uneconomical. This is a common problem [...]

Difference Air Preheater and Economizer

Difference Air Preheater and Economizer Although both preheaters and economizers are devices used to improve boiler thermal efficiency, their operating principles and functions differ. Preheaters primarily heat condensate, reducing feedwater transportation power consumption; economizers utilize flue gas waste heat to heat air before it enters the boiler, thereby reducing flue gas emissions and improving [...]
