technical field

The utility model relates to the technical field of boilers, in particular to a novel burner with a material slope and an interlayer water jacket.

Background technique

At present, the state pays more and more attention to the development and utilization of biomass energy, and the state and local governments at all levels have increased their support, which has brought great benefits to the development of biomass briquette fuel and its processing equipment, biomass stoves and boiler industries. Here comes the opportunity. Stove products that can burn biomass continue to emerge to meet the needs of different consumer groups, and are of great significance to improving and improving the indoor air quality of farmers, improving people's health, and promoting the construction of new countryside.

Under this premise, many biomass stoves have appeared on the market, but after investigation, it was found that the existing biomass stoves on the market are still not perfect, and there are still various defects.

For example, the Chinese patent "A Water Heating Stove Special for Biomass Granules" (publication number CN214619683U, publication date 2021-11-05) discloses a water heating furnace, including a furnace body, a feeding mechanism is provided on one side of the furnace body, and the feeding mechanism A control mechanism is arranged on the side; a blower is arranged under the feeding mechanism; the control mechanism is electrically connected to the blower; a cooking furnace mouth is arranged on the top of the furnace body, a heat releasing chamber is arranged under the cooking furnace mouth, and a combustion chamber is arranged under the heat releasing chamber; There is a water jacket on the outside of the outdoor; the lower part of the combustion chamber is located under the water jacket, and an air inlet channel is arranged, and the air inlet end of the air inlet channel is connected with the air outlet of the blower; Wind end middle.

Although this product has made improvements to traditional stoves, it solves the problems that traditional stoves cannot meet the oxygen consumption requirements, resulting in insufficient combustion and unsatisfactory burnout rate. However, this product still has defects. The biomass fuel is a granular compressed material. When the biomass particles enter the furnace body from the feeding mechanism, they will be piled up in the middle of the furnace body, resulting in insufficient combustion and a waste of resources. In addition, when this product is working, the biomass particles are directly accumulated on the grate. After a long time of use, the grate is easily damaged by high-temperature roasting.
