Description

A kind of biomass gasification fired energy-conservation stove

Technical field

The utility model relates to a kind of coal-saving device of gasifying biomass materials combustion energy saving device, especially Domestic stove.

Background technology

Energy savings is the eternal theme of current society, and saving each ton coal is the whole world, especially the common heartfelt wishes of the deficient countries and regions people of coal resource.In the vast rural area of China, resolve hundreds of millions peasants and herdsmen's family expenses cooking fuels and heating problem, be key subjects of building a New Socialist Countryside.In vast farming and pastoral area, renewable resources such as abundant weeds, leaf, agricultural crop straw are arranged, but how to take leave of the straight firing method that traditional smoke fire burns formula, make it be converted into the clear energy sources burning and utilize, be one of scientific and technological circle's urgent problem.Realize China's sustainable economic development, utilize regenerative resource imperative.China has obtained encouraging success aspect biomass gasification fired at present, as the family expenses stalk gasifier, adopt a bigger work durm pack into stalk or firewood, it is tight to light bonnet, with air blast with the mixtures such as flue gas CO that produce in the tube, blow to special-purpose kitchen range by pipe network assembly purification separation such as many iron pipe valves, threeways and light, to reach biomass gasification fired purpose.Though adopt this device can play certain biomass gasification fired purpose, but it is installed and the relative trouble of operation, still have harmful substances such as flue gas, tar, sulfide to follow in the use, and still need the air blast power consumption, be difficult to use at areas without electricity in indoor special stove ambient contamination.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, easy for installation, need not special stove, need not the supply lines valve connection, need not the air blast electricity consumption, with living beings anoxic in stove aerogenesis of heating, gas purifies at furnace high-temperature, and fully burns the back to the incorporate domestic biomass material of outdoor discharging gasification, and combustion energy saver by the twice aeration oxygen supply.

For reaching above purpose, this device is by the gas combustion chamber 5 on heat aerogenesis chamber 2 and top thereof, and semi-circular material bin 1 and the semi-circular water storage chuck 7 of encircling these two chambers, boiler face platform water storage chuck 9, fireworks channel 10, flue water storage chuck 11 and heating hot water outlet 12 and water filling port 18 are formed.

It is characterized in that: the gas combustion chamber 5 that heat aerogenesis chamber 2 and diameter are bigger is one from bottom to top, and the outer wall of these two chambers is encircled by semi-circular material bin 1 and semi-circular water storage chuck 7 respectively.Bottom at semi-circular material bin 1 communicates with the aerogenesis chamber 2 of heating, and gas combustion chamber 5 one sides have secondary blast mouth 6, and a cooking pot mouth 14 is arranged at top, and opposite side communicates with fireworks channel 10.Semi-circular water storage chuck 7 inner communicating with flue water storage chuck 11 and boiler face platform water storage chuck 9 are a water storage loop body.A UTILIZATION OF VESIDUAL HEAT IN pot mouth 15 is arranged on the top of fireworks channel 10.Outer wall at flue water storage chuck 11 has a heating hot water outlet 12 and water filling port 18.Lateral wall at semi-circular water storage chuck 7 has a heating water return mouth 13.

Adopt above structure, after coal (or honeycomb briquette) 17 burnings owing to heat on the fire bars 4 of bottom, aerogenesis chamber, heat to more than the burning-point for the biomass material of semi-circular material bin 1 bottom, biomass material is fuel gas such as aerogenesis CO under the high temperature anoxia condition, the gravitation of taking out by chimney 16 and fireworks channel 10, rise to gas combustion chamber 5, because the ventilation oxygen supply of secondary blast mouth 6, fuel gas such as CO moment fully burns and forms powerful flame, thereby satisfies the cooking requirement and heat each water storage chuck internal water and outer circulation is heated treating.Fuel gas such as CO also are processes through impurity such as high temperature purification flue gas, tar in the process that rises by the aerogenesis chamber 2 of heating.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Accompanying drawing 1 and accompanying drawing 2 are structural representations of the utility model energy-saving combustion apparatus.

1. semi-circular material bins among the figure; 2. the aerogenesis chamber of heating; 3 ventilating openings; 4. fire bars; 5. gas combustion chamber; 6. secondary blast mouth; 7. semi-circular water storage chuck; 8. smoke burner; 9. boiler face platform water storage chuck; 10. fireworks channel; 11. flue water storage chuck; 12. heating hot water outlet; 13. heating water return mouth; 14. cooking pot mouth; 15. UTILIZATION OF VESIDUAL HEAT IN pot mouth; 16. chimney; The coal 17. heat (or honeycomb briquette); 18. water filling port.

Embodiment: as scheme allegedly, the gasification, and combustion energy saver mainly is with biological material anoxic in stove generation fuel gas of heating, and through the twice aeration oxygen supply fuel gas is fully burnt and is a kind of domestic energy-saving Pollutioless stove and range of one.Mainly containing a semi-circular storage bin 1 and semi-circular water storage chuck 7 encircles at the outer wall of aerogenesis chamber 2 and gas combustion chamber 5 of heating, semi-circular material bin 1 leads to the aerogenesis chamber 2 of heating from the bottom, the material is here heated to the above temperature of burning-point to material through the coal 17 of heating under anoxia condition, make material produce fuel gas such as CO, taking out under the graviational interaction of chimney 16, fuel gas rises to gas combustion chamber 5 through aerogenesis chamber 2 high temperature purifications of heating, run into the ventilation of secondary blast mouth 6 at this fuel gas, realize that completing combustion produces powerful flame, use for cooking, and the water of the continuous on the way semi-circular water storage chuck 7 of heating and boiler face platform water storage chuck 9 and flue water storage chuck 11 internal reservoir, provide heating and bath hot water by heating hot water outlet 12 and heating water return mouth 13 to the external world.

The gasification, and combustion energy saver of this structure must guarantee negative pressure operation in the stove, in case fuel gas is from material bin refluence suitable for reading during use.Water filling port 18 must keep communicating with extraneous, must not stop up or valving, in case the airtight pressure-bearing of water storage chuck.In addition, will note in the use in the water storage chuck must not lack of water, with overfiring-proof furnace wall steel plate.
