Performance characteristics of Wantai biomass burner
1) High complete combustion efficiency: the design of boiling semi gasification combustion and tangential swirling air distribution makes the combustion complete and the combustion efficiency can reach more than 90%.
2) Combustion is complete and stable: the equipment operates under micro positive pressure, without flashback and desquamation.
3) Wide range of heat load adjustment: the heat load of the combustion engine can be adjusted rapidly within 30% - 120% of the rated load, with fast start and sensitive response.
4) No pollution and environmental protection benefits are obvious: renewable biomass energy is used as fuel to realize the sustainable utilization of energy. Low temperature staged combustion technology is adopted to reduce the emission of NOx, SO2 and dust in flue gas. It is the best substitute for coal stove.
5) No tar, waste water and other waste discharge: adopt high temperature gas direct combustion technology, tar and other direct combustion in the form of gas, solve the technical problem of high tar content in biomass gasification, and avoid the secondary pollution of water quality caused by washing tar.
6) Simple operation and convenient maintenance: automatic feeding, wind dust removal, simple operation, small workload, single person on duty.
7) High heating temperature: the technology adopts three times of air distribution, and the furnace pressure is 500-700mm water column to ensure the normal fluidization of the jet area. It can be used in continuous production with stable flame. The temperature of high temperature section can reach 1300 ℃, which is suitable for industrial application.
8) Wide range of equipment application: biomass burning machine is suitable for civil boilers, small utility boilers, kilns or other heating equipment.
9) Low investment and operation cost: the biomass combustion mechanism is reasonably designed, with low transformation cost when it is used in various boilers. The heating cost of the biomass combustion mechanism is 50% lower than that of the oil fired boiler during operation. It is an ideal choice for energy conservation and environmental protection of electric furnace, oil furnace and gas furnace.

Working principle
The main components of biomass fuel combustor include: automatic control system, high temperature cracking gasification combustor and combustion nozzle.
The biomass fuel combustor is simple and efficient. Its basic working principle is: the biomass particle fuel enters the high-temperature cracking semi gasification combustion chamber through the automatic feeding system, while the gasification agent (air and water vapor) is supplied from the lower part of the furnace, and the high-temperature gas is produced by the high-temperature cracking reaction under the oxygen deficient state in the high-temperature cracking gasification combustion chamber. In this process, the "sensible heat" and the combustible components such as CO, H2, CH4 and CnHm are produced, and the outlet temperature can reach 300-400 ℃; the gas directly enters the high-temperature combustion chamber with sufficient oxygen through the gas nozzle and burns completely, releasing the "latent heat".

Scope of application
Biomass burner products are widely used in steam boiler, die-casting machine, industrial furnace, incinerator, smelting furnace, kitchen equipment, drying equipment, food drying equipment, ironing equipment, paint equipment, road building machinery, industrial annealing furnace, asphalt heating equipment and other heat energy industries.
On the other hand, the biomass burning machine can also be used to deal with some hazardous solid wastes, such as pharmaceutical residues (including toxic and harmful substances such as antibiotics), papermaking residues (including carcinogens), urban garbage, waste oil, waste organic solvents, etc., by means of high-temperature heating to eliminate the toxic and harmful ingredients, but also generate energy, because of sufficient combustion, there will be no black Smoke and odor generation.
