Coal fired boiler - Guideline for energy efficient

Flue gas temperature: Flue gas temperature to chimney must be as low as possible. Lower temperature in flue gas indicated higher energy conversion in boiler. acid dew point must be considered while lowering temperature. Flue gas heat may be utilized in preheating boiler feed water or combustion air.
