Abstract
PURPOSE: To prevent overheating and enable continuous air flow, picking up slight flow to cause overheating of low pressure turbine, opening the pressure control valve fully by its signal, by controlling air bleeding pressure with the pressure control valve on the side of high pressure turbine.
CONSTITUTION: When the inlet pressure of low pressure turbine 23 decided to steam flow of the lower pressure turbine 23 is less than the pressure 14, the valve 24 is opened fully. On the other hand control valve 33 is opened immediately to the opening according to air flow. The pressure drop before and behind the valve is decreased, the steam expansion curve moves from the state 1 state 2 state 3 state 11 state 10 state 6, the state of outlet of low pressure turbine 23 moves to the state 6 in safety zone. Thus air bleeding running can be carried out under the state which turbine displacement is small, safety and performance is improved.
