摘要: A coupling system of copper slag recycling and CO2 mineralization process based on industrial solid waste includes the following steps: obtaining copper slags, performing a slag forming treatment, obtaining reforming slags, obtaining sponge iron, coupling the reforming slag with a CO2 mineralization process based on industrial solid waste, and coupling the CO2 generated in the process of obtaining sponge iron with the CO2 mineralization process based on industrial solid waste. The system includes a slag forming treatment device, a secondary treatment device, a first coupling device, and a second coupling device. The coupling system couples the recycling of copper slag with the existing CO2 mineralization process based on industrial solid waste. Various production lines can be organically integrated in a green and clean manner for both reforming slag and flue gas.

摘要: 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.

摘要: Disclosed is a combustion process of a glass kiln with non-catalytic reformers. A corresponding system includes the glass kiln, the non-catalytic reformers A/B, a flue gas recovery device, a chimney, a high-temperature flue gas fan, a natural gas supply device, and an oxygen supply device. The present disclosure circulates part of flue gas of the glass kiln and increases concentrations of vapor and carbon dioxide in the circulating flue gas, the vapor and the carbon dioxide in the circulating flue gas are subjected to a conversion and reforming reaction with natural gas in the non-catalytic reformers for recycling sensible heat of the high-temperature flue gas and meanwhile generating high-calorific-value water gas at 1300° C. or above, thereby increasing a gross calorific value and a temperature of gas entering the glass kiln, and the high-calorific-value water gas, less unreacted natural gas, and oxygen are sufficiently combusted in the glass kiln.
