A gas quench tower of a flue gas generator utilizes an incoming water stream at ambient temperature to cool the flue gas stream. Hot water discharged from the flue gas quench tower can be pumped to a variety of destinations, including the flue gas generator to be utilized as boiler feed water having an elevated temperature, thereby reducing the fuel demand for the boiler. Water may also be used to supply hot water demand to a building or may be utilized in an absorption chiller to provide chilled air. The oxygen content of the feed air delivered to the flue gas generator may be enriched by use of a membrane unit which provides a permeate stream having an enriched oxygen and carbon dioxide content to replace normal combustion air, reduce consumption of fuel gas, and further concentrate the CO2 and water in the flue gas.

The present application discloses a gas cooling apparatus and a heat furnace. The gas cooling apparatus comprises a pipeline structure. The pipeline structure defines a gas flow channel and a liquid channel; the gas flow channel is used for circulating a high-temperature gas; and the liquid channel is located outside the gas flow channel and is provided with a liquid spraying part communicated with the gas flow channel. The pipeline structure is further provided with a gas spraying part communicated with the gas flow channel; and a liquid sprayed from the liquid spraying part can be atomized under the action of the high-temperature gas in the gas flow channel and the high-pressure gas sprayed from the gas spraying part. The gas cooling apparatus has the advantages of simple structure, convenient use, rapid cooling rate for a high-temperature gas, and less use of a cooling liquid.
