Abstract
A regenerative air preheater leakage recovery system comprising a coal-fired steam generator in fluid communication with a regenerative air preheater. The regenerative air preheater adapted to provide a heat exchange between a flow of cool air and of hot flue gas to convert the cool air into the heated combustion air exiting to the steam generator. A combination of seals for effecting at least one plenum that is in fluid communication with the heated combustion air flow and the flow of hot flue gas relative to the regenerative air preheater. A captured flow of leakage, diverted from the flow of heated combustion air and directed by means of a fan to re-enter the regenerative air preheater at a location substantially separate from where the flow of cool air is received in the regenerative air preheater to be further heated therein and exit as the flow of heated combustion air.
