Description

A kind of biomass combined gasification furnace
Technical field
The present invention relates to a kind of stove and accessory, especially a kind of stove and accessory that makes the biomass fuel gasifying burning.
Background technology
At present, biomass furnace generally has two kinds of technical schemes, and a kind of is half gasification, and combustion, and a kind of is full gasification, and combustion.Full gasification is that biomass material is placed in the gasification furnace, produces fuel gas (containing carbon monoxide, hydrogen, methane, ethane etc.) by Pintsch process and physical reaction reduction back, and gas is transported to gas-cooker by pipeline and lives for people and use energy.Just belong to this class type of furnace as producer patent (ZL02277000.3) technology, though leading in the middle of the gasification furnace technology at present, remain the technical deficiency aspect following three: a wants gas-distributing fan; Contain wood tar in the b combustion gas; C uses raw material certain requirement.The technology of half-gasification oven tool is mainly taked once to fill up material and is down burnt from last igniting; utilize three oxygen supplys of secondary to reach gasification, and combustion simultaneously; do not reach requirement as raw material granularity, fineness degree, quantity and density, burning is extremely unstable, easily produces flue gas; in addition; long-time use is reinforced very inconvenient, charging again after ceasing fire or stopping working, in addition; in order to solve nature oxygen supply deficiency, a lot of producers also mix blower fan and replenish.
Summary of the invention
The objective of the invention is to overcome the deficiency of above full gasification or half-gasification oven tool, the technical advantage that reaches the two kinds of stove and accessorys that partly gasify that gasifies is entirely organically combined, provide a kind of and do not produce tar need not use blower fan, gasification, and combustion the time, can avoid secondary pollution, raw material to adapt to biomass combined gasification furnace wide, easy to operate, stable performance.
Biomass combined gasification furnace provided by the invention, have gas making case, burner hearth, burner, the gas making case is positioned at the sidepiece of burner hearth, burner is installed on roof of the furnace, the oxidation combustion tube is arranged in the gas making case, one end of oxidizing fire pipe communicates with the outer atmosphere of stove, the other end of oxidizing fire pipe communicates with burner hearth, on the oxidizing fire pipe gas port is arranged, the burner hearth sidepiece is provided with charge door, and upper furnace has the oxygen supply hole, there is the periphery of the burner hearth part in oxygen supply hole to be provided with oxygen supplying chamber, oxygen supplying chamber communicates with the outer atmosphere of stove, and the multilayer oxygen supply hole is arranged in the burner, and the multilayer oxygen supply hole communicates with the outer atmosphere of stove.
Described oxidizing fire pipe is obliquely installed, and charge door and combustion tube are located along the same line;
Described charge door is provided with dodge gate.
Described burner has multi-level tubular or the longitudinal cross-section is down trapezoidal distribution plate, and the multilayer oxygen supply hole is set on the distribution plate, and the distribution plate periphery is provided with air supply chamber, and air supply chamber and atmosphere are connected.
Described blast pipe is a three-way pipe, and lower nozzle stretches out furnace bottom and connects atmosphere, and two mouths of pipe communicate with the oxygen supplying chamber of upper furnace and the air supply chamber in the burner respectively in addition.
Described burner top is provided with secondary combustion chamber, and secondary combustion chamber is connected chimney, is stamped the hole of being convenient to place cooker on the secondary combustion chamber.
The movable seal cover of installing is arranged on the described gas making case, be convenient to add gas making fuel.
The air inlet of described burner hearth bottom, gas making case bottom and oxidizing fire pipe has grate respectively, and grate has grey storehouse; Burner hearth bottom also is provided with drying chamber.
Using method of the present invention is, at first ignition substance is joined in burner hearth and the oxidizing fire pipe from the burner hearth charging aperture, open the removable cover on the gas making case then, load onto comburant in the gas making case, capping then, ignite from the charging aperture igniting, burner hearth ignite the after-combustion thing progressively the oxidizing fire pipe in the gas making case extend, material obtains Pintsch process generation fuel gas in the gas making case when combustion tube burning back self-heating makes, simultaneously, the fuel gas that contains moisture and tar is back to by oxidizing fire pipe gas port and obtains the secondary high temperature degradation in the burner hearth, makes moisture and tar be converted into high-quality gas in the burner internal combustion.
The present invention has following good effect: (1) does not need blower fan when using, but also gas-distributing fan, but firepower is more violent, is applicable to the restaurant; (2) raw material adapts to wide: any or multiple all right in the biomass fuels such as firewood, wood chip, weeds, stalk, discarded object; (3) energy-conservation: per kilogram raw material incendivity one hour; (4) firepower calorific value height: chamber temperature can reach 700-800 ℃; (5) do not have flue dust and tar during gasification, and combustion, do not have secondary pollution; (6) easy to operate, use equally with traditional bavin kitchen range, be fit to mass consumption; (7) stable performance does not influence burning when using refuelling continuously, flame is very stable; (8) thickness fuel all can use: it is good that charge door and oxidizing fire pipe are suitable for adding Coarse Aggregate and firewood (diameter at the 7-8 kilogram, long 60-70 centimetre), is suitable for adding powder, stalk material in the gas making case.
