US3835650A - Steam air preheater for a steam boiler system ...

A steam boiler system includes a steam air preheater disposed in inlet ducting for preheating intake air. A boiler feed pump provides high-pressure water to a boiler which in turn produces steam to drive a main turbine. Exhaust flow from the turbine is routed directly to a main condenser with the exception of a small extraction flow which is used to drive a boiler feed pump turbine.

Air preheater The air preheater uses the hot feed water to preheat the combustion air and obtain a cool water flow in the return. This cold flow can now be used in an additional economiser bundle to further reduce the flue gas temperature. This increases efficiency by 2% points or flue gas temperatures that are roughly 40K lower.

Air Pre-Heater - an overview | ScienceDirect Topics

Primary air is supplied through an air distributor at the bottom of the reactor. Secondary air is supplied through ports along the vertical wall of the reactor. Each of these air supplies utilizes a dedicated forced draft fan. The primary air is heated using an air pre-heater prior to entering the reactor. Raw feed ash is pneumatically conveyed from existing storage silos to a process feed bin.
