The specific embodiment
In conjunction with the accompanying drawings, a kind of efficient low row's biomass stove of board-like poly-fiery crater, it comprises by furnace panel 1, urceolus 2 and poly-burner dividing plate 3 forms the body of heater 6 that contains furnace chamber 4 and lower furnace chamber 5; Establish fire-stop ring 7 on the poly-burner dividing plate 3 of last furnace chamber 4, in order to make full use of heat, the time of prolong smoke in stove, reach the environmental protection smoke evacuation, between fire-stop ring 7 and the furnace panel 1 clearance channel 12 is set, this clearance channel 12 is the interior flue of stove; It is communicated with body of heater 6 flue 10 outward; Be convenient carrying and chimney installation, the connector 18 of flue 10 is arranged at furnace panel 1 one sides and concordant substantially with furnace panel 1; Furnace panel 1 is provided with seat pot mouth 17; For the heating surface area of the pot of inviting guests to be seated reaches maximum, seat pot mouthful 17 internal diameters size is big or small consistent with fire-stop ring 7 internal diameters.The poly-burner dividing plate 3 of lower furnace chamber 5 is divided into propellant bottle 8, for sufficient combustion, between propellant bottle 8 and the poly-burner dividing plate 3 clearance channel 13 is set, and the size of this clearance channel 13 is by the decision of type of furnace size, and this clearance channel 13 is secondary air or claims the secondary air passage; Propellant bottle 8 barrels are established the charge pipe 9 that is communicated with urceolus 2 barrels, and when needing to add fuel in the use, then fuel is directly from 9 mouthfuls of interpolations of charge pipe; Urceolus 2 barrels of last furnace chamber 4 are established the flue 10 of connection, and poly-burner dividing plate 3 central authorities are provided with the poly-fiery crater 11 of internal diameter less than propellant bottle 8 internal diameters; For the volume space in the compressed fuel tube 8, fuel savings makes heat, firepower more concentrated, and it is littler than propellant bottle 8 internal diameters to reach poly-fiery crater 11 internal diameters, and specifically implementing proportion is 5%-95%, and the best is 65%; For structure is simpler, grate 14 directly is arranged at propellant bottle 8 bottoms, and air intake passage 15 is set on the grate 14 one time; In order to ensure enough ventilations, in lower furnace chamber 5 bottoms total air intake passage 16 is set, comprise the bottom and the air intake passage of side, i.e. air intake, secondary air overall channel.
Shown in accompanying drawing, the operation principle and the operating mode of efficient low row's biomass stove of a kind of board-like poly-fiery crater of the present utility model: following is to carry out cooking in not using air blast, improper pot of reinforced technical measures; Before the cooking, earlier fuel is dropped in the propellant bottle 8 through poly-fiery crater 11 from the mouth of pipe of charge pipe 9 or from seat pot mouth 17, its wind is entered in the lower furnace chamber 5 by total air intake passage 16 of urceolus 2 bottoms, the bottom that enters propellant bottle 8 by an air intake passage 15 on the grate 14 is combustion-supporting again, secondary wind also is that the total air intake passage 16 by urceolus 2 bottoms enters in the lower furnace chamber 5, clearance channel 13 through propellant bottle 8 tops enters the fuel top of propellant bottle 8 inner chambers, reaches abundant oxygen supply; Because poly-fiery crater 11 internal diameters of poly-burner dividing plate 3 central authorities are less than propellant bottle 8 internal diameters, flame, flue gas, fugitive constituent had stop and compression, prolonged flame, flue gas, the fugitive constituent time of staying in stove greatly, make all fully burnings of tar in flue gas, the fugitive constituent, improved temperature and crater temperature in the stove greatly, reduced furnace surface temperature and exhaust gas temperature simultaneously again and do not had the black smoke discharging; Because propellant bottle 8 relative urceolus 2 are shorter, are in again in the lower furnace chamber 5 of urceolus 2, air is very unobstructed in the chamber, can store the required oxygen of a large amount of burnings, because sufficient oxygen environment is arranged, it is very abundant to burn, the thermal efficiency increases a lot, poly-fiery crater 11 temperature are very high, and intensity of fire is big, do not have the black smoke discharging, littler because of poly-fiery crater 11 internal diameters again than propellant bottle 8 internal diameters, all heat energy all concentrates on the bottom of a pan, so furnace panel 1 temperature reduces, exhaust gas temperature also reduces.The utility model is fit to user's custom very much, fire big, adds some material more, little fire, then adds some material less.
