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 Pre-Heater - an overview | ScienceDirect Topics

Based on the high efficiency Sigma Stirling engine which includes an air pre-heater, it can be seen in Fig. 8.9 that the residual heat in the flue gases is passed to a heat exchanger in the return water from the primary heating circuit as it is at too low a temperature to add significantly to the temperature of the flow from the engine. In early versions of the WhisperGen engine, flue gases
