Effectiveness of using Steam Coil Air Heater
(OP)
I would like to ask question. In Steam power Plant, is it effective to operate Steam Coil Air Preheater when we used natural gas as the fuel?..which do you think is better, Operating or not operating steam coil air preheater when we use natural gas as the fuel?
Thanks for your attention

RE: Effectiveness of using Steam Coil Air Heater
What does your steam balance look like? If the steam used in the air preheaters is in surplus then it's essentially 'free' and using it makes sense. If you have to let down steam you are generating to condense it in the air preheaters then it makes no sense to do so because of the boiler inefficiency.
Another factor is that if you are combustion air limited then you'll likely reduce steam production capacity running the air preheaters because you have to flow hot air rather than cooler air to the boiler firebox.

They are particularly important in trash-to-energy plants or where a oad of biomass fuel may be delivered wet....

There are cold-end corrosion benefits as well..........you should know how all components function and operate on your specific plant !!
