ABSTRACT:
An apparatus for reheating stack gases leaving a plurality of scrubbers which uses water within an associated steam generator as the heating source. A heat exchanger receives heat from the boiler water transferring it to a low pressure fluid which is circulated through heat exchange surfaces downstream of each of the scrubbers. The flow of the high pressure boiler water is controlled in response to a temperature of the low pressure fluid thereby providing a means for minimizing the flow and return temperature of the high pressure water. The high pressure water is taken from a circulating pump discharge and returned to the circulating pump suction.
