STEAM PRODUCING SYSTEM USING WASTE HEAT OF REGENERATIVE THERMAL OXIDIZER

摘要

A steam producing system is provided to maximize energy utilization by returning waste heat to a combustion chamber after being used as a heat source for a boiler and permitting a secondary heat exchange for heating a thermal accumulation material. A steam producing system(1) comprises a combustion chamber(10) for burning noxious gas; a plurality of thermal accumulation chambers(20) arranged in a lower portion of the combustion chamber, shield by a separation wall, and equipped with a thermal accumulation material(21); and a channel converting unit(70) for connecting a noxious gas inlet pipe and a clean air outlet pipe to each thermal accumulation chamber. The combustion chamber is equipped with an overheat prevention bypass pipe. The steam producing system further includes a bypass return pipe(30) extracted outwardly from the combustion chamber and arranged as a heat source of a boiler(40). The bypass return pipe re-enters the combustion chamber after producing steam and cool heat exchange.
