Boiler Efficiency - an overview | ScienceDirect Topics
The combustion air for the boilers is supplied from two air handlers, east and west, that feed outside make-up air to the boiler house. In the winter the air handlers heat the incoming air using natural gas. This provides heat to the building and warms the air up prior to the entering boiler. Combustion air temperature effects boiler efficiency. A 40 degree variation in ambient temperature can affect efficiency …
