Description

Technical Field

[0001] The invention relates to the technical field of wall-mounted boilers, and in particular to a condensing gas-fired wall-mounted boiler. Background Art

[0002] When ordinary wall-mounted boilers are in operation, fuel (such as natural gas) and air are mixed and burned to generate energy for heating water or other heat transfer media, and then the smoke generated by the combustion is discharged. In addition to the basic principle of ordinary wall-mounted boilers, condensing wall-mounted boilers also have the function of recovering the heat of condensed water in the flue gas and reusing it. This is because there is unused steam in the flue gas, and these steam can be condensed through special heat exchangers to release more heat. In simple terms, when gas is burned, part of the energy is converted into flue gas and volatilized, most of which is water vapor; through special design, the water is cooled and heat is released to achieve a higher conversion rate.

[0003] The prior art provides a condensing gas wall-mounted boiler (publication number CN114061146B), which includes a gas inlet pipe, a proportional valve, a burner, a heat exchanger and a fan. The application solves the problem that the scale in the heat exchanger pipeline is generally cleaned by manually disassembling the heat exchanger, which will cause a lot of time consumption and increase labor costs. If chemical reagents are used for cleaning, the subsequent treatment of acid-base neutralization is also very troublesome. However, the technical solution still has the following technical problems in actual implementation: the interior of the conventional gas wall-mounted boiler is The heat exchanger does not exchange heat in a manner similar to a heat exchange tube. The heat pipe inside the wall-mounted boiler is generally heated directly by the outer flame of the burner. At the same time, the application uses a fan wheel to drive a scraper to scrape and clean the inner wall of the heat exchange tube, and the fan wheel is driven to rotate by the water flow inside the heat exchange tube. During actual use, the fan wheel is only rotated by the driving force of the water flow, and it is difficult for the scraper to effectively scrape the inner wall of the heat exchange tube. In addition, structures such as the fan wheel and the scraper will also produce scale and other attachments on the surface of the heat exchange tube, which makes it difficult to disassemble and clean. Summary of the invention
