no. 1 Embodiment approach
[0047] First, the first embodiment will be described.
[0048] (constitute)
[0049] figure 1 It is a schematic diagram showing the configuration of the thermal power generation system according to the first embodiment.
[0050] The thermal power generation system 100 has a power generation system 101 that uses coal as a raw material to generate electricity, an exhaust gas treatment system 102 , a water treatment system 103 , and a water vapor recovery system 104 in the exhaust gas.
[0051] The power generation system 101 is composed of the following components: a pulverizer 1 that pulverizes coal, a pulverized coal combustion boiler 2 that generates high-pressure and low-pressure steam by burning pulverized coal, and a low-pressure steam and high-pressure steam generated by heating the pulverized coal combustion boiler 2 The low-pressure steam turbine 11 and high-pressure steam turbine 12 that convert the pressure energy into rotational energy, the generator 13 that is co...
no. 2 Embodiment approach
[0101] Next, a second embodiment will be described. However, the same reference numerals are given to the same components as those in the first embodiment, and overlapping descriptions will be omitted.
[0102] (constitute)
[0103] Figure 5 It is a schematic diagram showing the configuration of the thermal power generation system according to the second embodiment.
[0104] The thermal power generation system 106 has a power generation system 107 for generating electricity using natural gas as a raw material, and a waste gas water vapor recovery system 108 for separating and recovering water vapor in power generation waste gas.
[0105] The power generation system 107 is composed of the following components: an air compressor 25, which takes in atmospheric air and compresses it; a gas turbine 26, which introduces the compressed air and fuel natural gas to burn them, and converts the expansion energy of these combustion gases into is the rotation energy; the waste heat rec...
no. 3 Embodiment approach
[0129] Next, a third embodiment will be described. However, the same reference numerals are given to the same components as those in the first embodiment, and overlapping descriptions will be omitted.
[0130] (constitute)
[0131] Image 6 It is a schematic diagram showing the configuration of the thermal power generation system according to the third embodiment.
[0132] The thermal power generation system 110 has a power generation system 111 for generating electricity using coal as a raw material, an exhaust gas treatment system 112 , a water treatment system 113 , and a water vapor separation system 114 in exhaust gas.
[0133] The power generation system 111 is composed of the following components: pulverizer 1, which makes coal into fine powder; pulverized coal combustion boiler 2, which burns pulverized coal to generate high-pressure and low-pressure steam; The low-pressure steam turbine 11 and the high-pressure steam turbine 12 that convert the pressure energy of t...
