Increase in the boiler s performance in terms of the acid dew
Boiler – Fundamentals and Best Practices
Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

WAYS TO IMPROVE THE QUALITY AND EFFICIENCY OF BOILER …
Also, reducing flue gas temperatures close to or below acid dew point incurs condensation/corrosion concerns that must be addressed by manufacturers One additional point is that potential for a market for installing economizer and air heaters on existing boilers could be created by government by setting up measures that require boiler owners to improve boiler efficiency, as mentioned above.
