When needs fire grate 3 rises, inwardly advance first push rod 46, drive bumping post 47 by push rod 46 and enter furnace external chamber 1 from locating hole 12, push rod 46 drives fire grate 3 along protruding guide rail 25 upward slidings in the thorax in the stove 2 by four activity bar, when grate 3 moves to suitable height, rotary handle 48 is stuck on the furnace external chamber 1 to drive corresponding bumping post 47 again, thus the position of dead grate 3; When needs fire grate 3 descends, elder generation's rotating push rod 46 is to remove the detent position between bumping post 47 and the furnace external chamber 1, outwards pull open again push rod 46 to move downward by four activity bar pulling grates 3, simultaneously, grate 3 also has downward trend under action of gravitation, fire grate 3 is moved down along protruding guide rail 25, when fire grate 3 drops to certain position, held no longer decline by ledge structure 72.
After regulating the height of fire grate 3, rotary handle 48, make bumping post 47 be stuck in the position of dead grate 3 on furnace external chamber 1 inwall, thereby the bottom of a pan is used in the flame optimum temperature range, add an amount of ignited fuel from pot circle 14, open drawer 71 wind is entered, increased the wind oxygen-supplying amount one time, stove is lighted rapidly, put the pot that needs heating.The design of wind gathering cover 33 can make a wind more concentrated, when fire grate 3 does not rise, a wind directly leaks 31 by ash and enters into thorax 2 in the stove, and after fire grate 3 rises, ash leakage 31 is at regular intervals with ledge structure 72, and a wind can directly not concentrated and enter into the combustion zone in the thorax 2 in the stove, so be provided with wind gathering cover 33, after fire grate 3 rose, wind gathering cover 33 can be concentrated a wind that to enter in the stove thorax 2 interior combustion-supporting.Simultaneously, air enters secondary air duct 11 by overfiren air port 17 first, enters thorax 2 in the stove by combustion air hole 23, fresh air inlet 24 again, makes fuel combustion more abundant.
In the burning, blow in stove in combustion air hole 23, fire-stop ring 16 can make high-temperature flue gas and flame form circulation in kitchen range, directly jump on the bottom of a pan, increase the heating surface area in the bottom of a pan, prolong the time of staying of high-temperature flue gas in kitchen range, improve temperature in the kitchen range, make the materials such as charcoal in the fuel and the fuel gas in the flue gas, solia particle, tar can be able to abundant burning, reduced the discharging of harmful substance, improved fuel availability.
If need to increase fuel, open reinforced lid 81 directly in the stove thorax 2 reinforced, do not affect normally cook, cooking, add reinforced lid 81 on the material bonnet, can not affect its normal combustion.
At the fixed carbon combustion phases, because fire grate 3 is arranged with elevating mechanism 4, rising elevating mechanism 4 is fully used the heat energy of fixed carbon, has improved greatly the thermal efficiency of biomass stove.Cinder catcher 32 concentrates on the bottom ash with fuel and leaks 31, and remaining ashes are concentrated on the drawer 71 who falls in the ash entrance chamber 7 behind the full combustion of fuel.The inwall of the furnace external chamber 1 of fire-resistant mud layer 15 between upper cover plate 6, pot circle 14 has played the effect of heat-insulation and heat-preservation.Heat-insulation layer 26 is positioned at cylindricality combustion chamber 22 outsides, and position corresponding with fresh air inlet 24 on it has heat-insulation layer hole 27, and heat-insulation layer 26 does not affect entering of Secondary Air in insulation, reduced the dissipation of heat.Therefore heat dissipation of the present utility model is little.
According to experiment, the best corresponding to the design hung fire and highly is respectively: burn faggot and be advisable with 14~20cm with the fire height that hangs of kitchen range, burning coal is advisable with 10~14cm with the fire height that hangs of kitchen range, the fire height that hangs of coal and firewood two purpose kitchen range is advisable with 12~16cm, hard bavin is advisable with 18~22cm with the fire height that hangs of kitchen range, and soft bavin is advisable with 15~20cm with the fire height that hangs of kitchen range.
