Abstract

The invention relates to a radial secondary decomposition combustion chamber of a biomass combustor. The radial secondary decomposition combustion chamber of the biomass combustor comprises a lower combustion chamber, a primary decomposition chamber and a secondary decomposition chamber which are all sequentially communicated. The lower combustion chamber corresponds to a bottom ring wrapping area of the lower portion of a combustion chamber wall. Lower air feeding holes are formed in the combustion chamber wall of an annular area at equal intervals. The secondary decomposition chamber corresponds to a secondary decomposition segment, namely the upper port area of the combustion chamber, of the combustion chamber wall, namely. Upper air feeding holes are formed in the combustion chamber wall of the annular area at equal intervals. The primary decomposition chamber is located on the upper middle segment of the combustion chamber and corresponds to a primary decomposition segment of the combustion chamber wall. According to the radial secondary decomposition combustion chamber, by arranging the lower combustion chamber, the primary decomposition chamber and the secondary decomposition chamber, fuel can be completely combusted, the coking degree in the combustion chamber is reduced, meanwhile heat can be evenly diffused to be transmitted upwards, and it is guaranteed that heat efficiency is stable.

Description

A kind of radial second pyrolysis combustion chamber of biomass burner

Technical field

The application relates to a kind of burner, particularly relates to a kind of radial second pyrolysis combustion chamber of biomass burner.

Background technology

In prior art, chamber structure mostly is cylindrical, bottom it or top be provided with air-supply structure, the combustion chamber of this kind of structure is because its burning position is mainly on bottom and top, cause in the middle part of combustion chamber and can retain a certain amount of imperfect combustion material, make the easy coking of Inner Wall of Combustion Chamber, after Long-Time Service, combustion chamber heat efficiency is reduced, energy consumption strengthens.Flame in the combustion chamber of this structure is simultaneously irregular divergent shape, and heat in a direction set, further cannot reduce the thermal efficiency.

Summary of the invention

It is simple that the object of the application is to propose a kind of structure, and thermal efficiency utilization rate is high, effectively can reduce the radial second pyrolysis chamber structure of the biomass burner of combustion chamber coking.

The object of the application be achieved in that biomass burner radial second pyrolysis combustion chamber it comprise the lower combustion chamber be communicated with in turn, a cracking room and second pyrolysis room, parcel region, foundation ring, described lower combustion chamber respective combustion chamber wall bottom, the chamber wall in this region of ring equidistantly offers bottom wind pushing hole; The second pyrolysis section of described second pyrolysis room respective combustion chamber wall, is upper port region, combustion chamber, the chamber wall in this region of ring equidistantly offers top wind pushing hole; A described cracking room is positioned at stage casing, combustion chamber, a cracking section of its respective combustion chamber wall.

The application can make fuel burn cmpletely by arranging lower combustion chamber, a cracking room and second pyrolysis room, reduces the coking degree in combustion chamber, heat can be made to be that even divergent shape upwards transmits simultaneously, ensures that the thermal efficiency is stablized.

Accompanying drawing illustrates: the concrete structure of the application is provided by following drawings and Examples:

Fig. 1 is the cross-sectional view of the radial second pyrolysis combustion chamber of biomass burner;

Fig. 2 is the structural representation of the radial second pyrolysis combustion chamber of biomass burner.

Legend: 1, chamber wall, 2, bottom wind pushing hole, 3, wind pushing hole, 4, foundation ring, 5, lower combustion chamber, 6, a cracking section, 7, cracking room, 8, the section of backing, 9, second pyrolysis section, 10, second pyrolysis room, 11, top wind pushing hole, 12, charging hole, 13, tie rod holes.

Detailed description of the invention: the application by the restriction of following embodiment, can not determine concrete embodiment according to technical scheme of the present invention and actual conditions.

Embodiment: as shown in Figure 1, 2, the radial second pyrolysis combustion chamber of biomass burner comprises lower combustion chamber 5, cracking room 7 and second pyrolysis room 10 of being communicated with in turn, region is wrapped up in foundation ring, described lower combustion chamber 5 respective combustion chamber wall 1 bottom 4, and the chamber wall 1 in this region of ring equidistantly offers bottom wind pushing hole 2; The second pyrolysis section 9 of described second pyrolysis room 10 respective combustion chamber wall 1, is upper port region, combustion chamber, and the chamber wall 1 in this region of ring equidistantly offers top wind pushing hole 11; A described cracking room 7 is positioned at stage casing, combustion chamber, a cracking section 6 of its respective combustion chamber wall 1.

One time cracking room 7 is the tubaeform of enlarging gradually, and cracking section 6 longitudinal section corresponding to it is the arc outwards stretched gradually.The air sent into by upper and lower part wind pushing hole 11,2 in a cracking room 7 carries out cracking burning to unburnt fuel, makes the flame of generation after burning or high-temperature gas upwards transmit in diffusion dress simultaneously.

The aduncate section of backing 8 is provided with between a described cracking section and second pyrolysis section.The section of backing 8 plays the flame or high-temperature gas inwardly concentrated gathering that are transmitted bottom, then passes to second pyrolysis room 10.

Second pyrolysis room 10 is that cavity is cylindrical, carries out second pyrolysis by top wind pushing hole 11 herein to also imperfect combustion fuel particles, makes it burn completely.

Described chamber wall 1 bottom also offers in a wind pushing hole 3 and charging hole 12, wind pushing hole 3 and arranges ajutage, and this ajutage is communicated with air blast.Arrange feed pipe in charging hole 12, feed pipe is communicated with hopper.

Foundation ring is reserved with axis hole and tie rod holes 13, and in order to install turnover frame flitch, described frame flitch is plectane, and it evenly offers some pores.

In use, the application is by consentrated air supply in a wind pushing hole 3 pairs of combustion chambers, and by the auxiliary air-supply of upper and lower part wind pushing hole 11,2, thus combustion chamber combustion is being burnt completely after lower combustion chamber 5, cracking room 7 and second pyrolysis room 10, the thermal efficiency significantly improves.

Obviously, the above-mentioned explanation of the application is only for the application's example is clearly described, and is not the restriction of the embodiment to the application.The technical scheme of every the application of belonging to the apparent change of amplifying out or variation be still in the row of the protection domain of the application.
