At present; Boiler is fuel used or in the majority with conventional raw materials such as coals; Along with the scarcity of coal resources, factors such as coal price rise, the drawback of coal-burning boiler also day by day highlights; Therefore, in a lot of local all appearance with the biomass fuel boiler as original fuel such as agricultural crop straw, tree branches, wood chip particle, city combustiblerefuse.According to statistics, by the end of the year in 2004, the whole world was that the biomass fuel generator installation total amount of representative has reached 3,900 ten thousand kilowatts with the stalk, can substitute 7,000 ten thousand tons of standard coals, is the summation of renewable energy power generation amounts such as wind-powered electricity generation, photoelectricity, underground heat.Thereby the popularization of biological fuel boiler has great importance for reducing fuel cost; Simultaneously, be very favourable replenishing for existing resource, also stalk, combustiblerefuse the like waste are used again; Turn waste into wealth, positive meaning is also arranged for environmental protection.
Biological fuel boiler of the prior art much all is that fuel is directly sent into the combustion chamber internal combustion, and some are arranged is through sending into combustion chambers burn again after simple fragmentation, the extrusion modling; This some problems occurred with regard to being accompanied by, and the material that acts as a fuel of promptly collecting is like stalk, particles, rubbish etc.; Often contain more water; Thereby can not realize completing combustion, thereby cause the waste of fuel to a certain extent, and produce more slag.Water-in-fuel is more simultaneously, also can produce more flue gas.
Therefore,, adapt to the needs of reality, be necessary to design a kind of novel biological fuel boiler, be intended to the structure of biological fuel boiler in the prior art is made certain improvement and innovation, realize the completing combustion of fuel as much as possible in order to overcome the deficiency of prior art.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, adapts to the needs of reality, and a kind of valve cock supporting mechanism is provided.
In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of biological fuel boiler comprises feeding chamber, the combustion chamber; Cooling chamber, said feeding chamber is provided with Z-shaped conveyer belt through the feed hopper feeding of top in the feeding chamber; The end of said conveyer belt is communicated with the combustion chamber through the lubricating substance groove, is provided with the oven dry hole between said feeding chamber and the combustion chamber, and said combustion chamber is provided with fire grate; The surface of combustion chamber is provided with slag-drip opening, and said combustion chamber is communicated with cooling chamber, is provided with high temperature superheater and low temperature superheater in the said cooling chamber; Said cooling chamber outside is provided with smoke discharging pipe, and the end of said smoke discharging pipe is a chimney, and said smoke discharging pipe is provided with blower fan.
The roller bearing of said Z-shaped conveyer belt is installed on the sidewall of feeding chamber, and Z-shaped conveyer belt divides the end of three layers and every layer all downward-sloping along transport path.
The fire grate of said combustion chamber is divided into two-layer, is respectively upper fire-grating and lower fire grating, and said upper fire-grating is a water-cooled iron and steel fire grate.
The outer surface of bottom, said combustion chamber is provided with the air outlet between upper fire-grating and lower fire grating.
The beneficial effect of the utility model is:
1. pass through the improvement to the conveyer belt of feeding chamber feeding, can make fuel before sending into the combustion chamber, just obtain oven dry, the heat that had both effectively utilized burning to produce has improved efficiency of combustion again;
2. double-deck fire grate structure makes that the burning of fuel is more complete, cooperates the air outlet of below, combustion chamber, can be better combustion-supporting; And
3. simple in structure, principle is simple, realizes easily.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model; And
Fig. 2 is the external structure sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of biological fuel boiler comprises feeding chamber 1, combustion chamber 2; Cooling chamber 3, said feeding chamber 1 is provided with Z-shaped conveyer belt 5 through feed hopper 4 feedings of top in the feeding chamber 1; The end of said Z-shaped conveyer belt 5 is communicated with combustion chamber 2 through lubricating substance groove 6, is provided with oven dry hole 7 between said feeding chamber 1 and the combustion chamber 2, and said combustion chamber 2 is provided with fire grate 8; The surface of combustion chamber 2 is provided with slag-drip opening 9, and said combustion chamber 2 is communicated with cooling chamber 3, is provided with high temperature superheater 10 and low temperature superheater 11 in the said cooling chamber; Said cooling chamber 3 outsides are provided with smoke discharging pipe 12, and the end of said smoke discharging pipe is a chimney 14, and said smoke discharging pipe 12 is provided with blower fan 13.Among the figure, 17 is the support of feeding chamber.
The roller bearing 15 of said Z-shaped conveyer belt 5 is installed on the sidewall of feeding chamber 1, and the end of three layers of Z-shaped conveyer belts 5 minutes and every layer is all downward-sloping along transport path.
Owing to be provided with oven dry hole 7 between feeding chamber 1 and the combustion chamber 2; So, before fuel gets into from feeding chamber 1, can be dried by the heat in the combustion chamber 2 in advance; Adopted the mode of movement of Z-shaped conveyer belt; What can guarantee to carry is convenient, has improved the transport path of fuel again, makes the heat that passes in the oven dry hole 7 can be good at fuel is dried in advance.Can above feeding chamber 1, exhaust outlet be set, make the steam of oven dry to discharge smoothly.
