Problems solved by technology
The existing combustion technologies are mainly grate layer combustion and fluidized bed combustion technology. Among them, the disadvantages of using grate layer combustion pots are incomplete fuel combustion and low thermal efficiency, while fluidized bed combustion furnaces can generally only be used For large boilers, the investment is huge and the production cost is high, so it cannot be widely used in small and medium-sized enterprises
The energy of the biomass gas produced by the two combustion technologies is low, which is not conducive to the efficient combustion of the boiler

Embodiment Construction
[0023] The burner is a regenerative burner, the diameter of the combustion chamber is 0.8m, and the capacity is 0.75m 3 . Such as Figure 1-3 As shown, the burner consists of a base 12, a cavity 20, an insulating layer 11, a refractory layer 9, an igniter 18, a feed pipe 15, a secondary air pipe 19, a partition 5, a tertiary air pipe 17, an air outlet pipe 8, Furnace cover 10, window 1 and explosion-proof door 13 are formed. The main structure of the burner is supported and fixed by the base 12 . The cavity 20 is in the shape of a hollow cylinder and is arranged horizontally. A refractory layer 9 is provided inside the cavity 20, and the refractory layer 9 is also a hollow cylindrical structure. The hollow cylindrical structure of the refractory layer 9 forms the combustion chamber 2 . Combustion chamber 2 is communicated with the feed pipe 15 that cavity 20 is provided with, and the axial inner wall of this feed pipe 15 is tangent to the transverse section inner wall of ...

The invention provides a vaporizing combustion chamber of high-energy biomasses, comprising a cavity and a hollow and cylindrical combustor, wherein the combustor is communicated with a feed pipe and an air outlet pipe; the air outlet pipe is horizontally arranged in the center of the combustor; the left end of the air outlet pipe is arranged in the combustor and taken as a built-in end; the right end of the air outlet pipe extends out of the combustor and is taken as an extended end; an air chamber is arranged between the cavity and the combustor and is connected with an air pipe; and the air outlet pipe is provided with a plurality of vent holes and communicated with the vent holes by the air chamber. In the vaporizing combustion chamber of high-energy biomasses, because the air chamberis arranged, so that the clean biomass gas is supplemented with oxygen before entering into a boiler, thus more energy can be obtained, the biomasses are boosted to fully combust in the boiler, and boiler combustion energy is exerted maximally.
Description
technical field [0001] The invention belongs to the field of energy preparation, and in particular relates to a combustion device for biomass gasification. Background technique [0002] With the continuous development of the world economy, energy and environmental issues have become increasingly prominent. The main energy sources currently used by human beings are oil, natural gas and coal. According to the statistics of the International Energy Agency, the lifespan of these three kinds of energy for human exploitation on the earth is only about 35 years, 50 years and 240 years respectively. On the one hand, fossil resources such as coal and oil are increasingly depleted, and energy supply continues to be tight; on the other hand, the excessive use of fossil resources has caused increasingly serious environmental problems. Therefore, developing and searching for new alternative energy sources has become a major issue that must be resolved in the new century for the sustain...
