Abstract

See full text

The present disclosure provides a method and a system for denitrogenation combustion and CO2 capture and utilization in a gas boiler. The method is implemented by the system for denitrogenation combustion and CO2 capture and utilization in the gas boiler, and comprises: after circulating flue gas is discharged from a gas boiler, introducing the circulating flue gas into a gas heat exchanger to perform heat exchange with natural gas, hydrogen, and carbon-based denitrogenation gas; introducing the circulating flue gas after heat exchange into a flue gas dehydration device to perform dehydration; introducing a first portion of the circulating flue gas after the heat exchange and dehydration into a blower through the flue gas dehydration device to be pressurized by the blower and introduced into a carbon-based denitrogenation gas mixer; preparing the carbon-based denitrogenation gas by mixing oxygen and the circulating flue gas using the carbon-based denitrogenation gas mixer for combustion for the gas boiler; and introducing a second portion of the circulating flue gas after heat exchange and dehydration into a CO2 recovery device to perform purification and deoxygenation through the flue gas dehydration device to obtain a CO2 product, and pressurizing and transmitting the CO2 product to a CO2 utilization device through a CO2 compressor.
