Abstract
The utility model discloses a kind of burner hearth of combustor, include furnace enclosure and burner hearth bucket, this burner hearth bucket is arranged in furnace enclosure, once blow layer and secondary blast layer is formed between the inwall of furnace enclosure and burner hearth bucket, this secondary blast layer is positioned at the top of layer of once blowing, this burner hearth headwall face is provided with a wind pushing hole and secondary blast hole, and this wind pushing hole is communicated with layer of once blowing, and secondary blast hole is communicated with secondary blast layer.By being provided with once blow layer and secondary blast layer, and be engaged on burner hearth bucket and be provided with a wind pushing hole and secondary blast hole, during work, granular fuel produces gasification in bottom by once blowing, a large amount of oxygen is run into when flue gas reaches the height of secondary blast, produce combustion reaction, effectively control the problem of combustor flue gas and improve the efficiency of combustion of combustor core.
Description
Technical field
The utility model relates to combustor art, refers in particular to a kind of burner hearth of combustor.
Background technology
Biomass combustion machine is a kind of biomass semi-gasification automatic control combustion engine, with biological particles, etc. the organic-biological matter biomass high-temperature cracking combustor that is fuel, be generally divided into air-cooled biomass combustion machine and water-cooled biomass combustion machine two kinds of types.Biomass combustion machine, burning cost is saved 75% than electricity, saves 60% than fuel oil, saves 50% than natural gas, is saved 40% than liquefied gas, and no pollution.Biomass combustion machine liner, adopts the crystallization of zirconium silicon, fires and forms, need the temperature more than 1000 DEG C to burn three days, without loose pore after high pressure cast through high temperature furnace.
But at present, the burner hearth be applied on combustor only adopts the mode of once blowing, and the structure of this kind of burner hearth easily produces smoke problem, and efficiency of combustion is extremely low, is necessary to improve existing burner hearth, to solve smoke problem, improve efficiency of combustion.
Summary of the invention
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of burner hearth of combustor, and it effectively can solve existing burner hearth and easily produce flue gas and the problem making efficiency of combustion low.
For achieving the above object, the utility model adopts following technical scheme:
A kind of burner hearth of combustor, include furnace enclosure and burner hearth bucket, this burner hearth bucket is arranged in furnace enclosure, once blow layer and secondary blast layer is formed between the inwall of furnace enclosure and burner hearth bucket, this secondary blast layer is positioned at the top of layer of once blowing, this burner hearth headwall face is provided with a wind pushing hole and secondary blast hole, and this wind pushing hole is communicated with layer of once blowing, and secondary blast hole is communicated with secondary blast layer.
Preferably, a described wind pushing hole is multiple, and a plurality of wind pushing hole is evenly laid on the lower end wall of burner hearth bucket.
Preferably, described secondary blast hole is multiple, and the plurality of secondary blast hole is evenly laid on the upper end wall of burner hearth bucket.
Preferably, described furnace enclosure cylindrically.
Preferably, the upper surface of described burner hearth bucket is concordant with the upper surface of furnace enclosure, and the lower surface of burner hearth bucket is concordant with the lower surface of furnace enclosure.
Preferably, be provided with horizontal baffle in described furnace enclosure and be separated to form aforementioned layer and the secondary blast layer of once blowing.
The utility model compared with prior art has obvious advantage and beneficial effect, specifically, as shown from the above technical solution:
By being provided with once blow layer and secondary blast layer, and be engaged on burner hearth bucket and be provided with a wind pushing hole and secondary blast hole, during work, granular fuel produces gasification in bottom by once blowing, a large amount of oxygen is run into when flue gas reaches the height of secondary blast, produce combustion reaction, effectively control the problem of combustor flue gas and improve the efficiency of combustion of combustor core.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in detail.

Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the utility model, include furnace enclosure 10 and burner hearth bucket 20.
This furnace enclosure 10 cylindrically, this burner hearth bucket 20 is arranged in furnace enclosure 10, the upper surface of this burner hearth bucket 20 is concordant with the upper surface of furnace enclosure 10, the lower surface of burner hearth bucket 20 is concordant with the lower surface of furnace enclosure 10, once blow layer 11 and secondary blast layer 12 is formed between the inwall of furnace enclosure 10 and burner hearth bucket 20, this secondary blast layer 12 is positioned at the top of layer 11 of once blowing, this burner hearth bucket 20 wall is provided with a wind pushing hole 21 and secondary blast hole 22, this wind pushing hole 21 is communicated with layer 11 of once blowing, secondary blast hole 22 is communicated with secondary blast layer 12.
In the present embodiment, this wind pushing hole 21 is multiple, and a plurality of wind pushing hole 21 is evenly laid on the lower end wall of burner hearth bucket 20, and this secondary blast hole 22 is multiple, and the plurality of secondary blast hole 22 is evenly laid on the upper end wall of burner hearth bucket 20.
And, be provided with horizontal baffle 30 in this furnace enclosure 10 and be separated to form aforementioned layer 11 and the secondary blast layer 12 of once blowing.
During work, granular fuel produces gasification in bottom by once air-supply, runs into a large amount of oxygen, produces combustion reaction, effectively control the problem of combustor flue gas and improve the efficiency of combustion of combustor core when flue gas reaches the height of secondary blast.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
