The invention discloses a flue gas waste heat recycling device for a medium-sized gas-fired boiler for heating. The flue gas waste heat recycling device comprises a boiler body and a compressor, wherein the left side of the boiler body communicates with a first flue; the left end of the first flue communicates with a combustor; the right side of the boiler body communicates with a second flue; theright end of the second flue communicates with an energy saver; and the right end of the energy saver communicates with a third flue. The invention relates to the technical field of heating equipment. According to the flue gas waste heat recycling device for the medium-sized gas-fired boiler for heating disclosed by the invention, the structures are matched, and an engine is utilized to drive a compressor to move, so that heat of high-temperature Freon in a flue gas waste heat recycling water tank is transmitted to secondary backwater, heat in flue gas is effectively recycled, an evaporator is in direct contact with flue gas, flue gas is circulated again for being further cooled, water in flue gas is reduced, the service life of a combustor is prolonged, floor space is small, maintenanceis simple, and emission of atmospheric pollutants is reduced.
Description
technical field [0001] The invention relates to the technical field of heating equipment, in particular to a medium-sized gas boiler flue gas waste heat recovery device for heating. Background technique [0002] Heating equipment is a heating facility set up to keep the space where people live or produce in a suitable thermal state. To heat a certain space, you can directly install the stove that generates heat in it; you can also extract the air in it, heat it and send it back; you can also install an object kept at a higher temperature in it, and release heat to the space where it is located. . This higher temperature object is called a heating radiator. In order to make the heating radiator continue to release heat, the preheated fluid can be used to continuously flow through the radiator. This fluid is usually steam or hot water and is called a heat transfer medium or heat medium. After the heat medium is heated by the heat generating, heat collecting or heat exchang...
