Above-mentioned double-walled biomass stove, including body of heater 1, the exhaust passage 2 being connected with body of heater 1 and inlet channel, inlet channel includes some main stove air inlets 4, and main stove air inlet 4 is located at body of heater 1 top, connects with body of heater 1 inside.Exhaust passage 2 includes exhaust passage import 21 and Vent passageway 22, and body of heater 1 top is located in exhaust passage import 21, connects with body of heater 1 inside.Exhaust passage import 21 is positioned at body of heater 1 center of top, and main stove air inlet 4 is distributed in around exhaust passage import 21.Inlet channel includes that some body of heater air inlets 6, described body of heater air inlet 6 are located at bottom body of heater 1, connects with body of heater 1 inside.Main stove air inlet 4 is provided with adjusting means one, and adjusting means one can regulate the air inflow of main stove air inlet 4;Body of heater air inlet 6 is provided with adjusting means two, and adjusting means two can regulate the air inflow of body of heater air inlet 6.The maximum intake of body of heater air inlet 6 is less than the maximum intake of main stove air inlet 4, and the maximum capacity of exhaust passage 2 is more than the maximum intake of inlet channel.Wherein, the numerical value height of exhaust passage 2 is 2m, the size of Vent passageway internal diameter is 0.8m, the internal diameter size of main stove inlet channel 4 is 0.2m, and total number of main stove inlet channel 4 is 6, and the internal diameter size of burner hearth inlet channel 6 is 0.1m, the number of burner hearth inlet channel 6 is 4, above numerical value is all through repetition test, the optimum drawn after accurately calculating, it is possible to the most cost-effective while fully meeting suck-back oxygen supply demand.Exhaust passage import 21 upper end is provided with main stove 3, main stove 3 is other is provided with secondary stove 5, main stove 3, secondary stove 5 and Vent passageway sequentially pass through pipeline communication, exhaust passage import 21 connects with main stove 3, burning waste gas, after exhaust passage import 21 enters, can sequentially pass through main stove 3, secondary stove 5 is finally reached Vent passageway 22.Being provided with furnace chamber dividing plate 9 in body of heater 1, the size of furnace chamber dividing plate 9 matches with the size within body of heater 1.Burner hearth baffle can fit with furnace interior (inboard wall of burner hearth), and moves up and down at furnace interior (in burner hearth), the size of regulation burner hearth, thus is organically adjusted the size of furnace chamber according to demand, thus ensures making full use of of fuel.Body of heater 1 includes the burner hearth 8 being placed within shell 7, and burner hearth 8 is isolated with shell 7, and the outer wall of burner hearth 8 does not contacts with the inside of shell 7, and body of heater 1 uses double-decker, by increasing capacitance it is possible to increase the heat-insulating property of body of heater;Exhaust passage import 21 connects with burner hearth 8 with main stove air inlet 4, and described burner hearth air inlet 6 is through shell 7 wall connection burner hearth 8 and extraneous air.Shell 7 outer wall is provided with some louvered shutters 71, and heat energy can quickly be distributed to indoor by louvered shutter 71, when biomass stove makes as heating of house purposes, increases the practicality of biomass stove.
This biomass stove uses a kind of oxygen-enriched combusting method in combustion, including: (1) air enters burner hearth from main stove inlet channel, main stove inlet channel is located at roof of the furnace, it is distributed in exhaust passage inlet ambient, biomass fuel burns from top to bottom, and burning waste gas is discharged through exhaust passage from roof of the furnace central authorities;(2) in combustion process, Vent passageway air pressure is less than exhaust passage inlet pressure, and burner hearth internal gas pressure, less than air pressure at main stove inlet channel, forms suck-back oxygen supply.Air enters burner hearth from main stove inlet channel, and main stove inlet channel is located at roof of the furnace, is evenly distributed, and lower portion of furnace body surrounding is also evenly distributed with burner hearth air inlet adjustment hole and plays combustion-supporting effect.Biomass fuel burns from top to bottom, burning waste gas almost completely from main stove flue through the chimney discharge chamber of exhaust passage;In combustion process, by changing the suction air inlet structure of tradition chimney, main stove and burner hearth internal gas pressure, less than exterior circumferential air pressure, are formed " suck-back oxygen supply ", are formed " oxygen-enriched combusting ".
Suck-back oxygen supply includes: (1) Vent passageway produces suction to exhaust passage import, and burner hearth center of inside is formed and rises fluid layer;(2) in rising fluid layer at Vent passageway, air-flow rises, and produces negative pressure in burner hearth, attracts air to enter burner hearth from main stove inlet channel;(3) air enters from main stove inlet channel, the internal surrounding's formation fall fluid layer rising fluid layer of burner hearth;(4) rising fluid layer to match generation siphonage with dropping fluid layer, air-flow has constantly circulated suck-back oxygen supply.
When burner hearth inlet channel is opened, air enters from burner hearth inlet channel, formed below liter of fluid layer of the combustion front of burner hearth endogenous substance fuel.
This biomass stove is used to comprise the following steps:
Step one: by regulation burner hearth baffle high and low position in burner hearth, regulation burner hearth, to suitable size, is put into biomass fuel, ignited by biomass fuel;
Step 2: close burner hearth inlet channel, closes the top of exhaust passage import, the most main stove upper end stuffiness, it is ensured that burning waste gas is discharged through Vent passageway, keeps main stove inlet channel to open;
Step 3: when the burning end face of biomass fuel is to time in the middle part of burner hearth, open burner hearth inlet channel, until bio-fuel burns completely.
If desired intake is adjusted, comprises the following steps:
Step one: regulation burner hearth, to suitable size, is put into biomass fuel, ignited by fuel;
Step 2: close burner hearth inlet channel, closes the top of exhaust passage import, it is ensured that burning waste gas is discharged through Vent passageway, keeps main stove inlet channel to open, and the intake size regulating main stove inlet channel controls combusting firepower;
Step 3: when the combustion front of biomass fuel is to time in the middle part of burner hearth, opens burner hearth inlet channel, the intake of regulation burner hearth inlet channel, along with fuel consumption, be stepped up the intake of burner hearth inlet channel, until bio-fuel burns completely.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
