Bioregenerative particle and powder mixed burner

Abstract

The invention provides a bioregenerative particle and powder mixed burner. A powder inlet, a particle inlet and a flame outlet tube are arranged on a burning chamber in a burning tank on a rack of thebioregenerative particle and powder mixed burner, a tube wall interlayer of the flame outlet tube communicates with a tank wall interlayer, and an interlayer outlet of the tube wall interlayer is located in the periphery of the port edge of an external port of the flame outlet tube; an air supplying mechanism is provided with a centrifugal fan, a bellow, a main air duct, and a combustion-supporting air duct, an air outlet of the centrifugal fan communicates with an internal space of the bellow, one end of the main air duct and one end of the combustion-supporting air duct communicate with theinterior of the bellow, the other end of the main air duct communicates with an ash chamber of the burning tank, and the other end of the combustion-supporting air duct communicates with the tank wall interlayer of the burning tank; a particle feeding mechanism communicates with the particle inlet of the burning tank through an inclined tube, and a powder feeding mechanism communicates with the powder inlet of the burning tank through a material check valve; a fuel injection nozzle of an ignition mechanism is arranged below a fire grate of the burning tank, and a controller is installed on the rack. According to the bioregenerative particle and powder mixed burner, bioregenerative particles and powder are used as mixed fuel, and the cost of the fuel can be effectively lowered.

Description

technical field [0001] The invention provides a burner which uses the mixture of biological regeneration particles and powder as fuel. Background technique [0002] Existing bio-regenerated pellet burners use recycled biomass pellets as fuel. Most of the recycled biomass pellets are processed from rice straw, corncobs, straw, rice husks, cottonseed hulls, peanut shells, etc. It does not contain sulfur and phosphorus, and does not produce sulfur dioxide and phosphorus pentoxide during combustion, so it will not cause acid rain, does not pollute the atmosphere, does not pollute the environment, and is more environmentally friendly. At the same time, biomass regeneration pellet fuel does not contain sulfur and phosphorus, does not corrode boilers, and It can prolong the service life of the boiler, and there is very little ash after the combustion of biomass regeneration pellet fuel, and the ash is a high-quality organic potassium fertilizer with excellent quality, which can als...

[0002] Existing bio-regenerated pellet burners use recycled biomass pellets as fuel. Most of the recycled biomass pellets are processed from rice straw, corncobs, straw, rice husks, cottonseed hulls, peanut shells, etc. It does not contain sulfur and phosphorus, and does not produce sulfur dioxide and phosphorus pentoxide during combustion, so it will not cause acid rain, does not pollute the atmosphere, does not pollute the environment, and is more environmentally friendly. At the same time, biomass regeneration pellet fuel does not contain sulfur and phosphorus, does not corrode boilers, and It can prolong the service life of the boiler, and there is very little ash after the combustion of biomass regeneration pellet fuel, and the ash is a high-quality organic potassium fertilizer with excellent quality, which can also be recycled to make profits and does not produce waste, so the biological regeneration pellet burner is used as The heat source of the boiler can benefit users a lot; however, in the existing technology, the processing and manufacturing of biomass recycled pellets is similar to the pelletizing method of pellet feed, which needs to go through drying, impurity removal, crushing, heating and pressing, cooling, packaging, etc. process, the above process requires the use of a variety of special machinery and consumes a large amount of electric energy. Due to the high cost of processing and manufacturing, the combustion cost of biomass regeneration particles as fuel is high, making it difficult to widely promote and utilize biomass regeneration fuel
