Embodiment Construction
[0028] The present invention is described in further detail below in conjunction with accompanying drawing:
[0029] Such as figure 1 As shown, the IGCC cogeneration system with high heat-to-electricity ratio described in this application includes a gasifier 1, a chilling unit 3, a dust removal unit 5, a waste heat recovery unit 6, a desulfurization unit 7, a syngas modulation unit 9, Combustion chamber 10, turbine 12, waste heat boiler 13, steam turbine 14 and peak heater 15.
[0030] The gasifier 1 is connected with water vapor and coal, and the gasifier 1 is connected with a cryogenic air separation system 2, and the cryogenic air separation system 2 is used to input pure oxygen into the gasifier 1.
[0031] The chilling unit 3 is connected to the gray water treatment unit 4. The crude syngas is quenched and cooled by water in the chilling unit 3, and gray water is generated at the same time, which is sent to the gray water treatment unit 4 to treat the gray water to avoid...
