Detailed description of the invention
1 is known with reference to the accompanying drawings, and the utility model is specifically related to a kind of novel environment friendly multi fuel clean burning stove and accessory, can be used for the burning of the fuel such as moulded coal (anthracite), anthracite, living beings and bituminous coal.Concrete structure comprises body of heater 4, feed bin 2 in body of heater 4 and combustion chamber 9, separated by water jacket partition between feed bin 2 and combustion chamber 9, and feed bin 2 is communicated with the bottom of combustion chamber 9, the top of combustion chamber 9 is communicated with the discharge flue 8 be located at above body of heater 4 side, and this structure is the structure of counter-burning type combustion furnace.The utility model makes improvements the structure of its combustion chamber, first fire grate 1 is provided with in the below of combustion chamber 9, the below of fire grate 1 is provided with the elevating mechanism that adjustable fire grate 1 moves up and down, and realizes fire grate 1 and slides up and down along combustion chamber 9 inwall, the size of adjustment combustion chamber 9.
The utility model using common bituminous coal as fuel time, adjustment combustion chamber 9 is maximum rating, now combustion chamber 9 is darker, combustion chamber 9 bottom space is large, can efficient after-flame after volatile matter material is mixed with air, the design of front storage bin facilitates the precipitation of fuel volatile matter, also can heat in advance fuel, improves the thermal efficiency; Now be conducive to the Thorough combustion of bituminous coal, living beings.When using moulded coal as fuel time, owing to being easily scattered into coal ash after moulded coal burning itself, easy blocking pore, makes other Combustion of Mould Coals insufficient, by improving the position of fire grate 1, combustion chamber 9 degree of depth is reduced, effectively can prevent the coal ash blocking pore that is scattered during Combustion of Mould Coal, make the nexine Thorough combustion of moulded coal, during burning, reduce the distance of moulded coal and heated body in addition, effectively utilize its thermal radiation temperature, improve the combustion thermal efficiency of moulded coal.
With reference to the accompanying drawings shown in 2 and 3, elevating mechanism of the present utility model comprises the lifting support 11 be located at below fire grate 1, and the thruster 12 driving lifting support 11 to move, wherein lifting support 11 is two right-angled intersection elongate rod, the upper end of two elongate rod and the both sides of fire grate 1 hinged, the lower end of two elongate rod is provided with roller, and two elongate rod infalls are connected by rotating shaft, and is provided with the chute of rotating shaft slip in the middle part of one of them elongate rod.Lifting support 11 is provided with two covers, lays respectively at the two ends of fire grate 1, and the lower end homonymy of two cover lifting supports 11 is connected by synchronous plate 11, and synchronous plate 11 side contacts with the push rod of thruster 12.This structure in use, only need promote lifting support 11 bottom by thruster 12, realize lifting support 11 and shrink, and promotes fire grate 1 simultaneously and rises, thus realize the lifting of adjustment fire grate 1.This structure is placed in the ash discharging chamber below fire grate 1, does not affect other structures of stove and accessory, can install separately, to increase cost low, convenient transformation.
In addition, elevating mechanism of the present utility model can also be other forms, such as adopts hydraulic cylinder, hydraulic cylinder is located at the below of fire grate 1, and the piston rod free end of hydraulic cylinder is connected with the lower surface of fire grate 1, also can realize above-mentioned functions, but cost of investment is relatively high.
It is tapered outlet that improvements of the present utility model also comprise top, combustion chamber 9, and contraction mode is linear contraction, and the bottom of formation combustion chamber 9 is roomy, outlet tapered configuration, covers adjustable fire sealing cover 5 above tapered outlet.Secondary air distribution combustion device 6 is located at above adjustable fire sealing cover 5, secondary air distribution combustion device 6 agent structure is cylinder, as shown in Figure 4, two end faces are provided with on cylinder top, leave gap between two end faces, two end faces are distributed with fire seperating hole, upper strata end face is spherical, its surrounding has a down dip, and the annular housing of secondary air distribution combustion device 6 side is communicated with secondary air inlet 10.This structure in use, can realize that Secondary Air fixedly has a down dip, bottom upwards divergent shape air distribution, the condition that burner and upstream high-temperature flue gas carry out convection current radiation heat transfer can be changed, strengthening ignition, extend the stop of combustible gas in stove on the other hand and be beneficial to after-flame burning time.Coordinate adjustable fire sealing cover, quantity-adjustable, be conducive to enhanced fuel burning, improve fire box temperature, strengthen oxygenation capacity in stove.
Can find out in fig. 1, the combustion chamber 9 in the utility model is communicated with discharge flue 8, sets up some row's heat-absorbing water pipes 14 in discharge flue 8, and heat-absorbing water pipe 14 is transverse direction, longitudinal arrangement, arranged askew or arc shooting.Discharge flue 8 is arranged side by side 3-5 root heat-absorbing water pipe 14 with the joining place of combustion chamber 9, gap herein between heat-absorbing water pipe 14 is that 0.5-1cm is advisable, spacing between reduction heat-absorbing water pipe 14 herein, can effectively reduce flow of flue gas speed, make it slowly spread, and be deposited in this intersection, and have cleaning door 15 bottom discharge flue 8, easy cleaning dust stratification, reduces dust emissions in flue gas.
Give the state diagram of the utility model when burning in figure 5, comprising air intake route.Be positioned at above fire grate 1 for slag layer, be burning zone above slag layer, utilize fire grate 1 upper-lower position different, the distance between adjustment burning zone and flame-gathering cover 7, raising radiation efficiency.Fire grate 1, as fuel, is upwards mentioned during burning by moulded coal or anthracite coal briquette, coal briquette burning time be easily scattered, Powdered coal grain by air-hole blockage, the nexine not easily Thorough combustion of coal, therefore coal seam can not be too thick; Anthracitic thermal radiation temperature and distance are inversely proportional to, and therefore combustion chamber 9 is more shallow, and anchracite ball combustion efficiency is better.Bituminous coal is as fuel, fire grate 1 is placed in bottom, now combustion chamber 9 is darker, combustion chamber 9 bottom space is large, can efficient after-flame after volatile matter material is mixed with air, the design of front storage bin facilitates the precipitation of fuel volatile matter, also can heat in advance fuel, improve the thermal efficiency, be now conducive to the Thorough combustion of bituminous coal, living beings.During the fuel of biomass fuel as stove and accessory, secondary air distribution combustion device 6 is taken off in the exit of combustion chamber 9, place adjustable fire sealing cover 5, fuel is filled it up with in feed bin 2, sealing charge door, and fire sealing cover is covered to main air inlet, because biomass fuel volatile matter is high, burning is very fast, needs lower oxygen supply when therefore banking up a fire.In addition, living beings lime-ash is in small, broken bits, easily sink under fire grate, and very hot oven district is on the low side, when refuelling is banked up a fire, very easily smolders, and by changing the position of fire grate 1, can solve this drawback.Combustion chamber 9 adopts low wide and up narrow structure, after fire grate 1 is carried, meets Combustion of Mould Coal, burner hearth rifling is short, the design feature of fire door linear contraction, can real briquet; Postpone under fire grate, can the higher solid fuel of the volatile matter such as efficient burning bituminous coal, living beings.The bottom air distribution of this structure is multiaspect divergence expression, and air distribution is evenly sufficient, and bottom multiaspect air distribution effectively can reduce slag temperature, reduces fluxing power; Furnace bottom oxygen transmission rate is high, is conducive to the Thorough combustion of fuel, also quantity-adjustable size.
