Description
Technical field
The utility model relates to a kind of boiler, and particularly a kind of is the boiler of fuel with living beings.
Background technology
It is the country of main energy sources with the coal that China is one, and coal-burned industrial boiler accounts for more than 80% of Industrial Boiler total amount.Coal belongs to non-renewable energy resources, because expanding economy, the demand of coal is constantly increased, and price rises steadily.And living beings are discarded objects of agricultural, production of forestry, if abandon burning arbitrarily, and can serious environment pollution.And sulphur, nitrogen content are all very low in the living beings, are reproducible clean energy resourcies, can replace the fuel of coal as boiler.Utilize living beings in boiler, to burn, produce that steam is used for producing, life or generating, have energy savings, reduce the social benefit of environmental pollution, good economic benefit is also arranged.
Propose in country's Eleventh Five-Year Plan, will greatly develop recycling economy, sustainable development from now on.
A domestic existing part is the boiler of fuel with living beings, has the problem that much needs solution:
(1) ignition temperature of living beings is low than coal-burning boiler, and the temperature of superheated steam does not reach design load.
(2) boiler seal poor performance, it is serious to leak out, and boiler efficiency is low.
(3) horizontal flue is heated and is prone to the phenomenon on the top of collapsing.
The utility model content
The purpose of this utility model is to provide a kind of efficient, low pollution, low emission, but the boiler of regenerative resources such as layer combustion living beings.
The utility model is achieved through the following technical solutions:
A kind of layer combustion biomass boiler comprises combustion apparatus 1, feeding system 2, horizontal flue 9, vertical well gas flue 10, and described feeding system 2 is connected the front end of combustion apparatus 1; Being positioned at combustion apparatus 1 top has a fin panel casing burner hearth 3, and fin panel casing burner hearth 3 is suspended on the brace summer 6 of boiler steelframe 5 by davit 4; Fin panel casing burner hearth 3 back connect horizontal flue 9 and vertical well gas flue 10 successively, and horizontal flue 9 entrances vertically are provided with high temperature superheater 7, and horizontal flue 9 upper horizontal are provided with steam 8.Described steam 8 is for being welded with the membrane wall structure of steel disc between superheater tube, combustion apparatus 1 is traveling-grate stoker or reciprocal grate.
The utility model compared with prior art, have the following advantages: the utility model is owing to increased steam, and steam is a membrane wall structure, increased the heating surface area of superheater on the one hand, can guarantee the quality requirements of superheated steam, cooling and supporting role preferably can be arranged the top furnace wall of horizontal flue on the other hand, and useful event can not occur collapsing; Owing to adopted burner hearth, the horizontal flue of membrane wall structure, can significantly reduce the flue inleakage, improve boiler efficiency, improve the boiler room working environment; Adopt traveling-grate stoker or reciprocal grate, improved the adaptability of boiler fuel.
Description of drawings
For ease of understanding the utility model, the spy is further described the utility model in conjunction with the accompanying drawings:
Fig. 1 is the related layer combustion biomass boiler schematic overview of the utility model.
Among the figure: the 1-combustion apparatus; The 2-feeding system; 3-fin panel casing burner hearth; The 4-davit; 5-boiler steelframe; The 6-brace summer; The 7-high temperature superheater; The 8-steam; The 9-horizontal flue; The 10-vertical well gas flue.
The specific embodiment
For the ease of understanding the utility model, the spy describes concrete structure of the present utility model, operation principle and embodiment in detail in conjunction with the specific embodiment, but present embodiment should not regarded as any restriction of the present utility model.
In conjunction with the accompanying drawings:
The utility model is made up of combustion apparatus 1, feeding system 2, fin panel casing burner hearth 3, davit 4, boiler steelframe 5, brace summer 6, high temperature superheater 7, steam 8, horizontal flue 9, vertical well gas flue 10 etc.Described fin panel casing burner hearth 3 is suspended on the boiler supports beam 7 by davit 4, is supported in the boiler foundation by steelframe 5; Described combustion apparatus 1 directly is installed in the boiler foundation; Described horizontal flue 9 is connected on the steelframe of vertical well gas flue by steelframe, and be supported in the boiler foundation, hang the version that prop up the back before the employing, can guarantee that steam generator system is when expanded by heating, the swell increment that furnace wall between combustion apparatus and the fin panel casing burner hearth can absorption piece expands and produces can not destroyed the hermetically-sealed construction of burner hearth under the effect of thermal stress.
Biomass fuel is sent in the fin panel casing burner hearth 3 by feeding system 2, on combustion apparatus 1, burn, after the high-temperature flue gas that burning produces washes away 3 heat exchange of fin panel casing burner hearth, enter horizontal flue 9, after being arranged on wherein high temperature superheater 7, steam 8 and carrying out heat exchange, enter vertical well gas flue 10, carry out heat exchange with the heat transmission equipment that is arranged on wherein, flue gas after the cooling is discharged boiler, discharging after the cleaner dedusting is up to standard.
Steam is the membrane wall structure that is welded with steel disc between superheater tube, cooling preferably can be arranged the top furnace wall of horizontal flue on the one hand, also the top furnace wall there are better seal and supporting role on the other hand, the accident of can occurred level flue crown wall not caving in.
Combustion apparatus can be according to the characteristic different mining of fuel with traveling-grate stoker or reciprocal grate.
Can arrange equipment such as low temperature superheater, economizer, air preheater as required in the vertical well gas flue.
