The company has developed a gas heating system and method based on carbon dioxide heat pump deep waste heat recovery, which belongs to the field of clean heating. The system includes: a gas boiler unit, a primary recovery unit for flue gas waste heat, a deep recovery unit for carbon dioxide heat pump waste heat, and a corresponding three-stage heating pipe network for the return water of the heat network. The system uses a carbon dioxide heat pump to further reduce the flue gas temperature of the gas boiler and realize low-temperature emission of flue gas. At the same time, the carbon dioxide heat pump is used to efficiently improve the quality of low-temperature waste heat. The system realizes the cascade utilization of energy through the grading recovery of flue gas waste heat and the grading heating of the return water of the heat network, which reduces the loss of gas energy and smoke exhaust, which can greatly improve the efficiency of the gas heating system and reduce the cost of gas heating. and gas heating pollutant emissions.
