Title:
COMBINED PROCESS FOR HIGH-EFFICIENT WASTE HEAT RECOVERY AND DENITRATION OF EXHAUST GAS OF GAS TURBINE
Document Type and Number:
WIPO Patent Application WO/2021/036099
Kind Code:
A1
Abstract:
A combined process for high-efficient waste heat recovery and denitration of exhaust gas of a gas turbine. Flue gas emitted from a gas turbine enters a flue gas denitration system, exchanges heat with saturated steam from a high-pressure drum by means of an overheat section of a high pressure boiler, then exchanges heat with high pressure boiler water from the high-pressure drum by means of an evaporation section of the high pressure boiler, then enters a denitration reaction bed layer by means of a blower to contact a catalyst for a denitration reaction, then exchanges heat with low pressure boiler water from a low pressure drum by means of an evaporation section of a low pressure boiler, and finally exchanges heat with the high pressure boiler water in an economization section of the high pressure boiler and is then exhausted via a chimney. High pressure steam and low pressure steam are generated by means of heat exchange of a high pressure drum and a low pressure drum with flue gas to recover waste heat in the flue gas, thereby improving the comprehensive utilization rate of a gas turbine, reducing running and investment costs, and implementing energy-saving and environmental protection requirements.
