Problems solved by technology
The above-mentioned soda water system has the following disadvantages: (1) The desalinated water in the desalinated water tank is directly fed into the deaerator, and a large amount of low-temperature desalted water (the temperature of the desalted water in the desalinated water tank is about 20°C) is fed into the deaerator, which will cause The low temperature of the deaerator will not only lead to chronic oxygen evolution corrosion damage of

The invention discloses a desalinated water replenishment system for a condensing steam turbine, comprising: a desalinated water tank is connected with a water replenishment port of a condenser throat through a desalinated water replenishment pipeline, and the condensed water outlet of the condenser passes through a valve and a condensate The water inlet pipeline of the water pump is connected with the water inlet of the shaft-sealed steam source heater, and the water outlet of the shaft-sealed steam source heater is connected with the water inlet of the low-pressure heater group through a connecting pipeline with a valve. The water outlet communicates with the water inlet of the deaerator through a connecting pipeline with a valve. The advantages of the present invention are: the water replenishment temperature of the desalted water entering the deaerator is increased, not only effectively avoiding the chronic oxygen evolution corrosion damage of the deaerator, improving the system safety, but also reducing the amount of heating steam required by the deaerator, improving On the other hand, it can reduce the exhaust pressure of the condenser, improve the thermal cycle efficiency of the steam turbine, and increase the power generation of the generator set.
Description
technical field [0001] The invention relates to the technical field of blast furnace gas power generation, in particular to a condensing steam turbine desalinated water replenishment system. Background technique [0002] The structure of the steam-water system of the gas-fired power generation condensing steam turbine currently used is: including the desalinated water tank, the water outlet of the desalted water tank is connected to the desalted water replenishment port of the deaerator, and the water outlet of the deaerator is connected to the inlet of the steam drum. The water port is connected, the steam outlet of the steam drum is connected with the steam inlet of the deaerator and the inlet of the steam turbine through the steam pipeline, the suction port of the steam turbine is connected with the steam inlet of the deaerator, and the exhaust port of the steam turbine It is connected with the air inlet of the condenser, and the condensed water outlet of the condenser is...
