Problems solved by technology

However, the steam input in the above-mentioned power generation equipment is the steam output from the steam turbine, or the steam generated by heating the mixed water of the condensed water that has been degassed and the condensed water that has not been degassed. Both steam and undegassed condensate have more dissolved gas, which results in a smaller degassing concentration gradient, so it takes a longer time to reduce the dissolved gas concentration in the condensate to the desired concentration

[0020] The first embodiment of the present invention is as figure 1 As shown, a steam turbine power plant 10 includes a steam turbine 12 , a generator 13 , a condenser 15 , a condensate receiving tank, a degasser 18 and an inert gas source 20 . After the steam enters the steam turbine 12 from the inlet of the steam turbine 12, the steam turbine 12 is started to move, and the internal energy is converted into mechanical energy, and the steam turbine 12 drives the generator 13 coupled to it to generate electricity.

[0021] The steam outlet of the steam turbine 12 is connected to a condenser 15 in which the outlet steam is cooled to condensed water. The condenser 15 can be a condenser known in the prior art, using air or gas refrigerant as a cooling medium. The degasser 18 is used to receive the condensed water, and the inert gas input through the inert gas source 20, or the steam input through the pipeline, removes the dissolved gas in the condensed water.

[0029] see figure 2 The difference between the second embodiment of the present invention and the first embodiment is that the steam generated by the waste heat recovery steam generator 31 is not used as the degassed steam in the degasser, and all of it is sent to the steam turbine 12 . Since the degassing steam in the degasser 18 has been generated by the steam generator 33 connected to the first condensate receiving tank 241, and the concentration of dissolved gas in the degassing steam is relatively small, so in the second embodiment, only It is used as the degassing vapor in the degasser 18 . And, since the degassed steam does not need to be used as the running steam of the steam turbine 12, after the steam turbine generating equipment is shut down for maintenance, the condensed water flowing out of the first outlet of the first condensate receiving tank 241 passes through the steam generated by the steam generator 33, Can also be used as a degassing fluid.

Abstract

The invention discloses steam turbine power generation equipment. The steam turbine power generation equipment comprises a condenser, a degasser, a first condensate receiving box, a second condensate receiving box, a steam generator and a waste heat recovery steam generator, wherein condensate water of one outlet of the first condensate receiving box communicates with the degasser through the steam generator, a steam outlet of the waste heat recovery steam generator just communicates with a steam turbine, and steam generated by the waste heat recovery steam generator is conveyed to the steam turbine without being conveyed to the degasser; after the steam turbine power generation equipment is maintained and stopped, condensate water flowing out from the first outlet of the first condensate receiving box can generate steam through the steam generator and can be used as degassing fluid.

Description

technical field [0001] The invention relates to a steam turbine power generation equipment, in particular to a steam turbine power generation equipment with a high-efficiency degassing device. Background technique [0002] In the steam turbine power generation device, the steam generator is used to generate steam for the steam turbine, and the steam drives the steam turbine to move, so that the generator coupled to the steam turbine generates electricity. In this case, the steam generated by the steam generator is condensed into condensed water in the condenser during use. [0003] The condensate in the condensate system has dissolved gases due to the presence of air in the steam generator as well as in the condenser. When the steam is condensed into water, the oxygen and carbon dioxide in the air are also dissolved in the condensed water, making the condensed water acidic. Acidic condensed water will corrode pipes and equipment, thereby affecting the life of steam turbine...
