Above sliding grate 4, any second outlet is respectively less than at a distance from import at a distance from any first outlet and import, so that one
It is formed and is spaced between a first outlet or the combination and a second outlet or the combination of multiple second outlets of multiple first outlets
Region, interval region are reducing atmosphere.
In use, such as coal solid fuel is sent by feeding structure to the first end of sliding grate 4, start portable furnace
Row 4, solid fuel enters combustion chamber 5 from entrance, burns in combustion chamber 5, and sends out from the exit of combustion chamber 5, is moving
The second end blanking of dynamic formula fire grate 4.Feeding structure can be additive bin, and sliding grate 4 can be continuous band fire grate, can also
To be chain furnace grate, the gap that there is gas supply stream to pass through on sliding grate 4.Supply air system send out wind be divided into First air and
Secondary Air, wherein First air is flowed out through first outlet and second outlet.The specific structure of supply air system is that the routine of this field is set
It sets, details are not described herein again.
First outlet is single or one group, and second outlet is single or one group, due to first outlet and second outlet interval
Certain distance, when solid fuel conveys in combustion chamber 5, the First air flowed out at first outlet is used for the kindling of solid fuel
Burning, and the fugitive constituent between first outlet and second outlet is precipitated region and is not sent into air then, so that the region is in reduction
Property atmosphere, advantageously reduces NOXGeneration, and at second outlet i.e. sliding grate 4 advance terminal region be re-fed into sky
Gas, for burning for the uncombusted object of remaining solid.
Similarly, above sliding grate 4, Secondary Air outlet is spaced apart with sliding grate 4, so that fugitive constituent
The region of gas burning is in reducing atmosphere first, advantageously reduces NOXGeneration, then burn region in gas and pass through feeding
Secondary Air, for burning for unburnt gas.
The NO that fire coal generatesXIt is mainly derived from the NO of nitrogen content of coal generationX, N referred to as in fuel bound nitrogen and air2, quilt
Referred to as heating power nitrogen, in addition there are minimal amount of quick nitrogen.The wherein generation of heating power nitrogen mainly has a direct relation with temperature, and fuel
The nitrogen that the generation of nitrogen then depends in fuel contains content and combustion reaction atmosphere.Researched of Air Staging Combustion Burning Pulverized Coal is current low nitrogen burning
Technical measures are widely used to coal dust firing, and expand to fluidized bed combustion and layer combustion combustion field.
The present invention uses air staged combustion technology, and cardinal principle is exactly to reduce air feed at combustion reaction initial stage, makes to fire
The intermediate product generated in burning is reduced into N because of the oxygen amount of reaction zone deficiency2, to inhibit NOXGeneration, and after combustion
Phase provides sufficient oxygen amount to complete burning for fuel.
Through the above structure, the three-dimensional fractional combustion in layer combustion combustion furnace is realized, it is ensured that be effectively reduced in combustion chamber 5
NOXGeneration, while can pass through and adjust air stage feeding ratio and the fire grate speed of service according to fuel combustion characteristics and fuel quantity
Guarantee while low nitrogen burning, improve efficiency of combustion, to realize efficiently low NOXBurning.
In the present embodiment, first outlet is multiple and is equally spaced along longitudinal direction, and second outlet is multiple and equidistant along longitudinal direction
It is distributed (first outlet and second outlet are three in Fig. 1, and other quantity also may be selected in those skilled in the art), position is adjacent
First outlet and second outlet fore-and-aft distance be greater than first outlet longitudinal pitch and second outlet longitudinal pitch.
The longitudinal pitch and second that the fore-and-aft distance of the adjacent first outlet in position and second outlet is greater than first outlet goes out
The longitudinal pitch of mouth, the purpose is to keep the oxygen concentration at 5 middle part of combustion chamber lower compared to the oxygen concentration of 5 inside two sides of combustion chamber,
To make the fugitive constituent at 5 middle part of combustion chamber that region (region between first outlet and second outlet) be precipitated in reducing atmosphere.
In the present embodiment, the longitudinal pitch of adjacent first outlet is preferably equal with the longitudinal pitch of adjacent second outlet.
The Secondary Air outlet of the present embodiment includes the 4th outlet and the 5th outlet, the height of the 4th outlet and sliding grate 4
Degree difference is greater than the difference in height of the 4th outlet with the 5th outlet, to make unburnt gas full combustion.4th outlet and the 5th goes out
Mouthful be it is multiple, third outlet and the 4th outlet the side wall of combustion chamber 5 circumferencial direction spaced at equal angles around, to make air
Combustion chamber 5 is uniformly passed through from all directions on 5 top of combustion chamber.
In the present embodiment, supply air system includes pressure fan 1, First air main pipeline 2, the first branch pipe, the second branch pipe, Secondary Air
Main pipeline 3, the 4th branch pipe and the 5th branch pipe.The first end of First air main pipeline 2 is connected to the air outlet of pressure fan 1, First air
The second end of main pipeline 2 is connected to the first end of the first branch pipe and the second branch pipe respectively, and the second end of the first branch pipe is to
One outlet air feed, the second end of the second branch pipe is to second outlet air feed.The first end and pressure fan 1 of Secondary Air main pipeline 3
