Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, be an embodiment of a kind of combustion formula of the utility model biomass boiler, comprise:
Body of heater 1, body of heater be divided into be interconnected heat producing regions 2, heat exchange area 3.Heat producing regions 2, for firing biomass fuel, produces heat; Heat exchange area 3, for the heat of flue gas and water are carried out heat exchange, reaches the object of heating.
Heat producing regions 2 comprises feed arrangement 20, combustion chamber 21, slag collection room 22, burner hearth 23.Feed arrangement 20 is auger type feed arrangement, by auger by fuel area density to discharging opening, reach the object of the inlet amount accurately controlling fuel, its discharging opening is communicated with the charging aperture being arranged at combustion chamber 21 sidewall.Slag collection room 22 is located at below combustion chamber 21, fire grate 24 is provided with between combustion chamber 21 and slag collection room 22, fire grate 24 is casting furnace grate, slag notch 26 on body of heater 1 outer wall corresponding with slag collection room 22, when the fuel afterburnt, it is inner that ashes can drop to slag collection room 22, cleaning by opening slag notch 26 pairs of boilers, easy and simple to handle.And fire grate 24 good heat resistance of cast iron, use cost performance very high in the boiler.
Burner hearth 23 is located at above combustion chamber 21, and the while that fuel being internally fired in combustion chamber 21, flame and flue gas are gushed out along with air-flow in burner hearth 23, the heat of release burning.Combustion chamber 21 sidewall is provided with symmetrical air distribution device 28, is provided with igniter 27 in the below of fire grate 24, the ignited fuel of igniter 27 for suspending, and the thermal current that fuel combustion produces also is that fuel can keep one of factor suspended.Because the gas flowing in stove is caused by the air-flow acting in conjunction manufacturing negative pressure and burning generation in stove of bleeding of air-introduced machine 4, therefore, the air distribution device 28 communicated with outside air carries out the supply of gas, makes pressure in stove be unlikely to too low, the oxygen simultaneously needed for aftercombustion; Because air distribution device 28 is oppositely arranged, can eddy current be formed in combustion chamber 21, keep the suspended state of fuel in combustion chamber 21, make burning more abundant.
The charging aperture place of combustion chamber 21 is provided with rotary blade, if there is part powder fuel to lump in feed arrangement 20, then directly can affects combustion efficiency, therefore add rotary blade at charging aperture place, the fuel of this caking can be smashed, improve efficiency of combustion further.The furnace body outer wall corresponding with combustion chamber 21 is provided with can the finder 6 of switch, and can observe the combustion case of fuel at any time, handled easily personnel make debugging to combustion process.
Heat exchange area 3 comprises the upper smoke box 32 being located at top, heat exchange area 3, the lower smoke box 33 being located at heat exchange area 3, the top of the body of heater corresponding with heat exchange area 3, bottom are respectively equipped with and the water inlet 35 of body of heater ft connection, delivery port 34, be communicated with by boundling flue 36 between upper smoke box 32 with lower smoke box 33, upper smoke box 32, lower smoke box 33, between boundling flue 36 and described body of heater, form water jacket 31, upper smoke box 32 is communicated with by flue with burner hearth 23, and lower smoke box 33 is communicated with the air-introduced machine 4 being located at body of heater outside by flue.Upper smoke box comprises the first upper smoke box 321, second upper smoke box 322 set gradually, lower smoke box comprises the first lower smoke box 331, second lower smoke box 332 set gradually, first upper smoke box 321 is communicated with by flue with burner hearth 23, and the second lower smoke box 332 is communicated with the air-introduced machine 4 being located at body of heater outside by flue.All be communicated with by boundling flue 36 between first upper smoke box 321 with the first lower smoke box 331, between the first lower smoke box 331 with the second upper smoke box 322 and between the second upper smoke box 322 with the second lower smoke box 332, make flue gas tortuous advance in described heat exchange area.This design adds the formation of flue gas in the body of road, too increases the contact area between pipeline and water, and then adds the efficiency of radiation heat transfer.
The air outlet of air-introduced machine 4 is connected with dust arrester 5.Owing to there is dust granules in flue gas, directly flue gas to environment, can pass into after cleaner purifies and discharges, can effectively reduce pollution level by discharge.
Use procedure:
First water is introduced in water jacket 31 by water inlet 35.Fuel is put into feed arrangement 20, auger is by the feeding discharging opening of quota of fuel.Fuel is through the charging aperture of combustion chamber 21, and period is rubbed again by rotary blade.Igniter 27 is by ignited fuel, and air distribution device 28 is also quantitative under the effect of negative pressure sends air into combustion chamber 21, keeps the suspended state of fuel.With igniter 27 pilot fuel, open air-introduced machine 4 subsequently and bleed, cause negative pressure state in stove.The flame that burning produces and flue gas enter burner hearth 23, then enter upper smoke box 32, boundling flue 36, lower smoke box 33 successively along with air-flow, and period carries out radiation heat transfer with peripheral water, and complete the heating to water, the water after heating is discharged from delivery port 34.Remaining flue gas is discharged along with air-introduced machine 4, then is discharged in air through the purification of dust arrester 5.
Adopt the structure that combustion chamber is built-in, make the compact conformation of boiler, floor space is little, not only the thermal loss of flue gas in conductive process can be reduced, the waste heat that combustion chamber can also be distributed in combustion is farthest kept in body of heater, increases radiation heat transfer efficiency.
