Abstract
A biomass composite furnace comprises a hearth (1), wherein the lower part of the hearth (1) is provided with an air inlet circuit (2) which is communicated with an air inlet channel (3), the hearth (1) is communicated with the air inlet circuit (2) through an oxygen supply hole (4), the upper part of the hearth (1) is provided with an oxygen supply circuit (5) and a gasification combustion chamber (6), the oxygen supply circuit (5) is located at the external periphery of the gasification combustion chamber (6), is communicated with the gasification combustion chamber (6) through an oxygen dispatching hole (7), and is communicated with an oxygen supply channel (8), and the upper part of the hearth (1) is provided with a movable fire sealing cover (12). The biomass composite furnace integrates the technology advantages of a complete gasification furnace and a half gasification furnace, when in use, oil tar and vegetable wax liquid are not discharged, peculiar smell is not generated, no smoke is generated in making a fire, firepower and temperature of gasification combustion is high, and the biomass composite furnace can choose fire sealing or fire off arbitrarily after being used, thus saving fuel and being convenient for use.
Description
Technical field
The utility model relates to a kind of stove and accessory, particularly a kind of biomass gasification fired stove and accessory.
Background technology
Along with becoming increasingly conspicuous of energy problem, the utilization of living beings regenerative resource is more paid close attention to by people's attention, the particularly research and development of living beings household gasification furnace more and more with exploitation, occurred a lot of products on the market.At present, the biomass gasifying furnace tool 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 by Pintsch process and physical reaction reduction back, and this type of gasification stove contains wood tar because institute produces in the combustion gas, and there is difficulty in popularization on a large scale.The technology of half-gasification oven tool is mainly taked once to fill up material and is down burnt from last igniting, utilizes three oxygen supplys of secondary to reach gasification, and combustion simultaneously.Existing half gasified bio-matter gasification stove burns extremely unstable, easily produces flue gas, and in addition, long-time use is reinforced very inconvenient, charging again after ceasing fire or stopping working.
Summary of the invention
The purpose of this utility model is to provide a kind of NEW TYPE OF COMPOSITE gasification stove, its no tar discharging, and non smoke when lighting a fire, the violent temperature height of gasification, and combustion firepower, reinforced convenient.
The technical solution of the utility model is: a kind of biomass combined stove, have burner hearth, lower furnace portion has the air intake circuit, the air intake circuit is communicated with air intake passage, burner hearth, is characterized in that to communicating by oxygen supply hole and air supplying ring, is provided with oxygen supply circuit and gasification combustion chamber in upper furnace, the oxygen supply circuit is positioned at the gasification combustion chamber periphery, the oxygen supply circuit communicates with gasification combustion chamber by oxygen-distributing hole, and oxygen supply circuit and oxygen supply channel connection are provided with movable fire sealing cover above burner hearth.
Be provided with refined zone outside gasification combustion chamber, refined zone is communicated with chimney.
Air intake passage and oxygen supply passage all are communicated with blower fan.On air intake passage and oxygen supply passage, be respectively equipped with valve.
Be provided with charging aperture at the burner hearth sidepiece, charging aperture connects feed arrangement.Feed arrangement has feeding-passage, and feeding-passage is provided with the feed hopper that communicates with feeding-passage, is provided with pay-off in the feeding-passage, and feed hopper is provided with movable seal cover.
Described pay-off has spiral propeller, and spiral propeller is connected with feeding channel rotary handle outward.
Described pay-off has propelling piston, and propelling piston is connected with feeding channel propelling handle outward.
The utility model combines the technological merit of full gasification furnace and half-gasification oven.Lighting a fire for the first time is after fuel is filled up to fire door, from last igniting, and adopts secondary air to reach gasification, and combustion.When reusing, can directly burn from last igniting, also can be from light a fire reformed gas burning of burner hearth bottom.No tar and haze tallow liquid discharging in the utility model use, free from extraneous odour, non smoke when lighting a fire, the violent temperature height of gasification, and combustion firepower can be selected arbitrarily to bank up a fire after use finishing or flame-out, fuel saving.
