Abstract

PURPOSE:To improve controllability of the turbine plant in the caption and to restrain the exhaust pressure rise of a superhigh-pressure turbine in starting the turbine plant, by providing a first and a second exhausters for connecting the exhaust sides of the superhigh-pressure and a high pressure turbines respectively to a condenser through a first and a second closing gears. CONSTITUTION:A reheat steam governing valve 23b for an intermediate- and a low-pressure turbines 11, 13 is first opened, so that a part of reheat steam is fed into the intermediate turbine 11 to rotate it until its speed becomes a given constant value. In this case, since both the internal pressure of a superhigh-pressure turbine 3 and that of a high-pressure turbine 7 are approximately vacuous, their windage losses are not generated, and the superheated conditions of their exhausts can be restrained. As a result, only those turbines 11, 13 are simultaneously monitored, so controllability can be improved. Then exhaust valves 42, 44 are fully closed as soon as governing valves 22, 23a for the turbines 3, 7 are opened. Consequently, the starting of the turbine plant concerned is carried out while main steam or reheat steam is fed respectively into turbines 3 and 7 so as to increase load together with air flow.
