Abstract
The present invention is a kind of improved hand-fired boiler grate, its multilayer grate is installed within the furnace foundation with parallel in twos being connected and fixed of a determining deviation by column, the grid zone of adjacent two layers grate and space region intermesh and overlap to form a plurality of annulars or circular combustion front, fuel all is in piles up rarefaction and obtain abundant burning, thereby avoid the ash fusion to form the phenomenon of clinker.
Description
The present invention is a kind of improved hand-fired boiler grate.
The available ventilation area of existing hand-fired boiler grid is limited in below 40% of grate area (ga), the coal seam is in the stack pile stratosphere, in case when using the big slightly inferior matter coal of ash, just owing to improper ventilation causes ashes to reach melting temperature melting phenomenon takes place, condense into the bulk lime-ash, the heavy damage combustion conditions.
For addressing this problem, common way is to increase the scarfing cinder number of times, the class burner that french patent application Fr2508140 proposes pulverulent solids fuel has the two-layer grate of doing relative motion, carries out periodicity deashing in combustion process, and the product after some are burnt is fallen in the ashcan, but for the hand-fired boiler that uses raw coal, this heater complex structure, and because grate area (ga) is big, solid fuel has stone, be difficult to realize relative motion, cross less than the purpose of improving combustion conditions.
A kind of hand-fired boiler grate that the objective of the invention is to overcome above-mentioned shortcoming and design, it can make the coal seam be in free accumulation, both sides rarefaction, not only enlarged the available ventilation area more than one times, and the staggered accumulation in coal seam, so material is loose, flowing resistance significantly reduces, and can avoid the ash fusion fully and forms clinker.
The task that the present invention proposes is realized by following measure: the multilayer grate is installed in the furnace foundation inwall by column with the parallel in twos connection of a determining deviation, the grid zone of adjacent two layers grate and space region intermesh overlapping to form a plurality of annulars or circular combustion front, make fuel all be in the accumulation rarefaction, can obtain oxygen simultaneously and be able to abundant burning from both sides and bottom surface.
The present invention is simple in structure, and scarfing cinder is convenient, not only energy savings but also help smoke abatement and dust control.
Concrete structure of the present invention is provided by following enforcement and accompanying drawing:
Figure one is the cutaway view of multi-layer intercrossed grate bar proposed by the invention.
Figure two is vertical views of part 1 among the figure one.
Figure three is vertical views of part 2 among the figure one.
Figure four is vertical views of part 3 among the figure one.
Working condition below in conjunction with description of drawings concrete device proposed by the invention.
This device is made up of upper strata grate (1), middle level grate (2), lower floor's grate (3), furnace foundation (4), column (5), three layers of grate (1), (2), (3) are installed on the inwall of furnace foundation (4) with the parallel in twos connection of a determining deviation by column (5), the grid zone of adjacent two layers grate and space region intermesh and overlap to form a plurality of annulars or circular combustion front, each combustion front all has enough ventilation side and bottom surface, assurance active combustion area separately all is in fuel and piles up rarefaction and obtain abundant burning.
Claims (2)
1, multi-layer intercrossed grate bar is made up of grate (3), furnace foundation (4), it is characterized in that:
A, grate are that multilayer grate (1), (2), (3) are connected and fixed on the inwall that is installed on furnace foundation (4) so that a determining deviation is parallel in twos by column (5).
The grid zone of b, adjacent two layers grate (2), (3) and space region intermesh overlapping to form several annular or circular combustion fronts.
2,, it is characterized in that being connected between grate (1), (2), (3) and the column (5) is dismountable according to the described multi-layer intercrossed grate bar of claim 1.
