Patent ID: 7987675

Claim:
A steam power plant in which steam, generated by utilization of heat of a heat source by a steam generator, is received by a steam turbine for use in power generation, the power plant comprising: a flowpath conduit to couple the steam generator and the steam turbine; a main steam control valve (MSCV) disposed along the flowpath conduit upstream of the steam turbine to admit the steam to the steam turbine when a characteristic thereof satisfies a threshold; a bypass line, coupled to the flowpath conduit between a super-heater of the steam generator and a conduit valve disposed upstream from the MSCV, the bypass line including a bypass line valve which is opened until the threshold is satisfied such that the bypass line removes a portion of the steam from the flowpath conduit; an evacuator line, coupled to the flowpath conduit between the MSCV and the steam turbine, including an evacuator valve which is opened to regulate a thermal environment within the steam turbine during a start up thereof; and a warming line, including a warming line valve, coupled to the flowpath conduit between the conduit valve and the MSCV and terminating on the evacuator line downstream of the evacuator valve, to remove an additional portion of the steam from the flowpath conduit.
