ABSTRACT:
A waste heat recovery boiler system has a plurality of waste heat recovery boilers each having a main steam generator and a reheater capable of generating main steam and reheat steam by heat derived from a hot waste gas introduced into the waste heat recovery boiler. The flows of main steam from the main steam generators are joined to form a single flow of main steam to be used in an external installation, and the flows of reheat steam from the reheaters are joined to form a single flow of reheat steam to be used in the external installation. The steam discharged from the external installation is distributed to the reheaters. Flow rate controllers are provided for controlling the flow rates of the steam through the reheaters in relation to the hot waste gas supplied to the respective waste heat recovery boilers.
