Technical Field

The invention belongs to the field of heating supplies, and particularly relates to a biomass combustion furnace and a using method thereof.

Background

Biomass, as a fuel, has been the longest and most widespread in human history. Particularly, as fossil fuels such as coal, petroleum, natural gas and the like are gradually lacked and mining and application have negative effects on ecological environment, the full utilization of biomass fuel resources becomes one of important ways for solving the problems of exhaustion of the fossil fuels and environmental pollution. However, the traditional simple biomass material combustion method has a plurality of negative problems:

1. the fuel is not fully combusted, and particulate matters are discharged to different degrees, so that the natural environment is polluted;

2. the heat energy utilization rate is low, and the energy waste phenomenon exists;

3. the combustion facilities have large floor space, heavy weight (inconvenient movement) and inconvenient operation, or external power facilities such as wind boxes, electric blowers and the like are required to be equipped;

4. the functions are single, and the functions of cooking, baking, heating and the like can be realized only in a single way;

5. the applied material has single shape, and the materials with different shapes such as straw, wood splitting, particles, briquettes and the like can not be compatible.

Furthermore, a sealing cover is arranged on the material bin.

Further, the biomass combustion furnace further comprises: and the oxygen valve is arranged on the oxygen pipe and used for adjusting the supply amount of the oxygen.

Further, the biomass combustion furnace further comprises: and the oven is arranged at the lower part of the oven body and is arranged at the periphery of the combustion chamber.

Furthermore, a flue gas pipeline is arranged at the top of the furnace body. The height ratio of the furnace body to the flue gas pipeline is 1: 3-1: 7.

Further, the biomass combustion furnace further comprises: convection tube, for both ends open-ended tubular structure, convection tube's one end is cold air inlet, and the other end is hot air outlet, convection tube's middle part is located the combustion chamber, wherein, hot air outlet is located the cold air inlet top.

Further, the biomass combustion furnace further comprises: and the hot air reversing plate is arranged on the furnace body and is positioned above the hot air outlet.

Furthermore, a clothes hanger is detachably mounted on the hot air reversing plate.

The invention also discloses a using method of the biomass combustion furnace, which uses the biomass combustion furnace, and the using method mainly comprises the following steps:

(1) throwing a small amount of fuel from the fuel passage;

(2) feeding a pilot charge into the combustion chamber to ignite the fuel;

(3) putting more fuel and sealing the top of the combustion chamber;

(4) outside air is delivered into the combustion chamber through an oxygen hose.

The biomass combustion furnace has the advantages that the combustion chamber is arranged at the middle upper part of the furnace body, and the grating can screen the embers and the ash to enable the embers and the ash to fall. The fuel passage can supply fuel from the top of the combustion chamber, and the oxygen pipe can supply oxygen required by the combustion chamber from the middle lower part of the combustion chamber.

When the biomass fuel ignition device is used, a small amount of biomass fuel is placed into the combustion chamber, and fire or other inflammable substances are thrown into the fuel channel to ignite the biomass fuel. After the biomass fuel is ignited, more biomass fuel is put in, and the fuel channel is closed, so that the top of the burning fuel is closed by more fuel, and oxygen at the top of the combustion chamber is almost prevented from entering the furnace body. The fuel is carried by the grating arranged at the middle upper part, a combustion space is still arranged at the lower part of the grating, and the biomass fuel added later isolates oxygen at the top of the combustion chamber, so that the air in the furnace body is consumed when the biomass fuel is combusted. After the air in the furnace body is consumed, the air pressure in the furnace body is reduced, and negative pressure is formed relative to the external air. Due to the pressure difference, the outside air is continuously delivered into the furnace body through the oxygen pipe, and the fuel is continuously combusted in the combustion chamber. Because the flame is flaming and combusted from top to bottom (the combustion chamber is in the furnace body), the condition of flaming under negative pressure is formed, the embers and the ash which are screened by the grating can be combusted secondarily, and the utilization efficiency of the fuel is improved.

And a fuel passage 131 disposed above the combustion chamber 11, the fuel passage 131 communicating with a top of the combustion chamber 11.

An oxygen pipe 50 is communicated with a middle lower portion of the combustion chamber 11 for supplying oxygen to the combustion chamber 11.

In the biomass combustion furnace of the present invention, the combustion chamber 11 is provided at the middle upper part of the furnace body 10, and the grate can screen the ashes and the ashes to make them fall down. The fuel passage 131 can supply fuel from the top of the combustion chamber 11, and the oxygen pipe 50 can supply oxygen required for the combustion chamber 11 from the middle lower portion of the combustion chamber 11.

In use, a small amount of biomass fuel is placed in the combustion chamber 11 and a fire or other combustible material is fed from the fuel passage 131 to ignite the biomass fuel. After ignition, more biomass fuel is put in, the fuel channel 131 is closed, so the top of the burning fuel is sealed by more fuel, so the top of the combustion chamber 11 is sealed, and oxygen at the top of the combustion chamber 11 is almost prevented from entering the furnace body. Because the combustion chamber 11 is located in the furnace body 10 and the biomass fuel isolates oxygen at the top of the combustion chamber 11, air in the furnace body 10 is consumed when the biomass fuel is combusted. After the air in the furnace body 10 is consumed, the air pressure in the furnace body 10 becomes small, and a negative pressure is formed with respect to the outside air. Due to the pressure difference, the external air is continuously supplied into the furnace body 10 through the oxygen pipe 50, and the fuel is continuously burned in the combustion chamber 11. Because the flame is flaming and combusted from top to bottom (the combustion chamber is in the furnace body), the condition of flaming under negative pressure is formed, the embers and the ash which are screened by the grating can be combusted secondarily, and the utilization efficiency of the fuel is improved.

Further, the biomass combustion furnace further comprises: and the material bin 13 is positioned above the combustion chamber 11, and the material bin 13 is communicated with the fuel channel 131.

Further, a sealing cover is arranged on the material bin 13. The cover may close the access to the top of the combustion chamber 11, reducing the oxygen supply to the top of the combustion chamber 11.

Further, the biomass combustion furnace further includes an oxygen valve 51 disposed on the oxygen pipe 50 for adjusting the supply amount of oxygen.

It will be appreciated that ambient air enters the combustion chamber through the oxygen tube 50 to participate in the combustion. In practice, the combustion state and the flame intensity can be adjusted by the oxygen valve 51, and when high intensity combustion is required, the oxygen valve 51 is adjusted to the maximum opening, whereas when the flame length needs to be reduced, the oxygen valve 51 is appropriately closed.

Further, the height ratio of the furnace body 10 to the flue gas pipeline 15 is 1: 3-1: 7, so that the flue gas can be combusted secondarily in the combustion chamber 11, the fuel can be combusted completely, and the emission of particulate matters is reduced.

Further, the biomass combustion furnace further comprises a convection pipe 20. Convection tube 20 is the tubular structure of both ends open-ended, convection tube 20's one end is cold air inlet, and the other end is hot air outlet, convection tube 20's middle part is located combustion chamber 11, wherein, hot air outlet is located the cold air inlet top.

It is understood that the convection tube 20 is not communicated with the combustion chamber 11, and the convection tube 20 heats the air inside the convection tube 20 mainly by the heat of the combustion chamber 11. Because convection current pipe 20 is both ends open-ended tubular structure, the air can get into from the cold air import that is located the below, and the cold air that is located convection current pipe 20 middle part is heated the back inflation and rises in combustion chamber 11, spills over from the hot-air outlet of top, and the hot-air that spills over can fast be in the air loss, improves ambient temperature, plays good heating effect.

Further, the biomass combustion furnace further comprises: and the hot air reversing plate 30 is installed on the furnace body 10, and the hot air reversing plate 30 is positioned above the hot air outlet.

It can be understood that, the cold air in the convection tube 20 is heated in the combustion chamber 11 through the heat conduction of the tube wall, and the expansion rises after being heated, because the convection tube 20 is a tubular structure, the air passage is narrow, the heated air is sprayed out from the hot air outlet above, the hot air reversing plate 30 is arranged above the hot air outlet, and can prevent the air from dissipating upwards after being heated, and press the hot air to the ground, so that the position temperature of the middle and low height is effectively improved, and the user can quickly feel the temperature rise, and a good heating effect is achieved.

Further, a clothes hanger 40 is detachably mounted on the hot air reversing plate 30. The hot air is blocked from the heated temperature by the hot air reversing plate 30, and the clothes aired on the clothes hanger 40 are dried.

Further, the biomass combustion furnace further comprises: a cooking platform 60 embedded on the side wall of the flue gas duct 15; wherein the flue gas duct 15 comprises a transverse duct section on which the bottom of the cooking platform 60 is located.

It can be understood that the flue gas pipeline 15 is a bent structure, the middle transverse pipe section is mainly used for being matched with the cooking platform 60, and the cooking platform 60 realizes heating by utilizing the heat of the flue gas, so that open-fire-free cooking is realized. Wherein the cooking platform 60 may be a plate-shaped structure with a recess provided therein.

Further, a furnace door 14 is arranged at a position of the furnace body 10 corresponding to the combustion chamber 11, and an observation port 141 is arranged on the furnace door 14.

It can be understood that the oven door 14 is a visual oven door, which is convenient for the user to observe the flame condition and adjust the fire power.

Further, the bottom of the furnace body 10 is provided with legs 16 for movement. The arrangement of the movable supporting legs can facilitate the movement of the furnace body 10 and the operation. Further, the legs 16 may be of a foldable construction to facilitate storage.

In addition, the biomass combustion furnace can effectively save energy, and the consumption and the price can be reduced by 40-60% compared with those of anthracite and natural gas; meanwhile, the multifunctional electric cooker has multiple functions of cooking, baking, heating and the like. The biomass combustion furnace is safe, simple, convenient and flexible to operate when in use, and can be started, stopped and freely moved immediately.

The use method of the biomass combustion furnace mainly comprises the following steps:

(1) a small amount of fuel is thrown in from the fuel passage 131;

(2) throwing pilot into the combustion chamber 11 to ignite the fuel;

(3) more fuel is put in, and the top of the combustion chamber 11 is closed;

(4) outside air is supplied into the combustion chamber 11 through the oxygen pipe 50.

When the biomass combustion furnace is used, a proper amount of fuel is added into the combustion chamber 11 through the fuel channel 131, the biomass fuel is ignited by fire or inflammable matters, more biomass fuel is put into the combustion chamber after the biomass fuel is ignited, the fuel channel 131 is closed, the top of the burning fuel is sealed by more fuel, and oxygen at the top of the combustion chamber is almost isolated from entering the furnace body. Since the fuel is carried by the grate arranged at the middle upper part, a combustion space is still arranged at the lower part of the grate, and the biomass fuel added later isolates oxygen at the top of the combustion chamber 11, the air in the furnace body 10 is consumed when the biomass fuel is combusted. After the air in the furnace body 10 is consumed, the air pressure in the furnace body 10 becomes small, and a negative pressure is formed with respect to the outside air. Due to the pressure difference, the external air is continuously supplied into the furnace body 10 through the oxygen pipe 50, and the fuel is continuously burned in the combustion chamber 11. Since the flame is flaming and combusted from top to bottom (from the combustion chamber 11 into the furnace body 10), a negative pressure flaming situation is formed, and the embers and the ash which are screened by the grid can be combusted secondarily, so that the utilization efficiency of the fuel is improved. Then, according to the application function requirement, the combustion state and the flame intensity are adjusted, when the high intensity combustion is required, the oxygen valve 51 is adjusted to the maximum opening, otherwise, when the flame length needs to be weakened, the oxygen valve 51 is appropriately adjusted to be small. When the biomass combustion furnace needs to be stopped, adding fuel is stopped, then the oxygen valve 51 is closed, the fuel in the combustion chamber 11 is extinguished due to oxygen deficiency, and after a small amount of ash is reduced to the room temperature, the ash receiving box 121 is pulled out and cleaned.
