Detailed description of the invention
The utility model is specifically related to a kind of biomass cooking heating dual-purpose stove, and its combustion medium is stalk briquette, has good smoke medicining dust-removing effect, and cooking ability is strong.This stove and accessory concrete structure comprises body of heater, storage bin 3 is divided in body of heater, burner hearth, flue 13 and ash discharge chamber, burner hearth is parallel with storage bin 3 side by side, ash discharge chamber is placed in the below of burner hearth and storage bin 3, flue 13 is located at above the side of burner hearth, the improvements of this stove and accessory are that burner hearth is divided into three layers, zone of heating from the top down successively, combustion chamber, vaporizer, wherein be provided with combustion chamber 9 in combustion chamber, combustion chamber 9 is the housing of cone shape, its small end engages with zone of heating, large end engages with vaporizer, housing is evenly equipped with the aperture of secondary air, combustion chamber 9 is communicated with zone of heating with vaporizer, secondary air duct 10 is provided with in burner hearth, secondary air duct 10 is communicated with the air inlet 11 of ash discharge chamber side with combustion chamber 9, like this owing to during the combustion of combustion chamber being negative pressure, air then enters combustion chamber from air inlet 11 along secondary air duct 10, through the aperture outside the combustion chamber of combustion chamber, converge with burned flame, form secondary oxygen supply burning, which enhance combustible fumes firing out rate high, thus decrease pernicious gas, such as sulfur dioxide, the discharge of carbon monoxide etc.
Because this stove and accessory is held concurrently cooking and heating two functions, in order to raise the efficiency in cooking or heating a certain period, be therefore provided with dismountable stone or metal plate for standing a stove on as a precaution against fire 5 at fire door 12 place of zone of heating, fire door 12 place is located at by stone or metal plate for standing a stove on as a precaution against fire 5, and the size of stone or metal plate for standing a stove on as a precaution against fire 5 is mated with fire door 12.When cooking, stone or metal plate for standing a stove on as a precaution against fire 5 can be made to dismantle, then the heat concentrated supply the bottom of a pan of combustion product gases generation, improves cooking efficiency, as shown in Figure 2; When not cooking heats separately, with stone or metal plate for standing a stove on as a precaution against fire 5 shutoff fire door, such high-temperature flue gas directly enters flue 13, improves heat supply efficiency, and also can extend fire-sealing time when banking up a fire, as shown in Figure 3.
In the utility model, the structure of flue 13 is improved, horizontally disposed water pipe 6 is distributed with in flue 13, flue sheet 7 is provided with between every layer of water pipe 6, one end of flue sheet 7 is fixed on flue 13 sidewall, the other end of flue sheet 7 is bent downwardly, and flue sheet 7 is divided into the gas channel of S shape flue 13, the part be connected with body of heater at flue 13 is provided with ash discharging hole 8.The gas channel of S shape makes high-temperature flue gas and water pipe 6 extend time of contact, improves heat utilization ratio, the arrangement form of flue sheet 7, can reduce the impurity such as the grey black in high-temperature flue gas and discharge, and ensures that cigarette ash etc. falls in flue 13, finally by ash discharging hole 8 periodic cleaning.
In order to improve the efficiency of secondary air feed, secondary air duct 10 and air inlet 11 being set to two, being located at left and right sidewall in burner hearth respectively, symmetrical air feed can be realized.
Charging aperture 4 of the present utility model for being obliquely installed the top in storage bin 3, and is protruding-type structure, is provided with sealing ring between charging aperture 4 and feed cap, and snap-fit engagement, facilitate feed and ensure sealing, preventing Combustible Gas Leak.
Test to structure of the present utility model and efficiency of combustion, the utility model global design is reasonable, and sealing is good, easy to operate, safe and reliable.Through experimental examination smoke discharge amount≤32mg/m
3, sulfur dioxide≤20mg/m
3, hydroxide≤114mg/m
3, carbon monoxide≤0.1mg/m
3, Ringelman flue gas blackness is less than 1 grade.Overall heating load reaches 13.7kW, and the thermal efficiency reaches 79.2%, and cooking intensity of fire is 2.7kW, and fire-sealing time is greater than 8 hours.Above-mentioned testing result, can meet the technical requirement of " biomass cooking heating stove tool general technical specifications " (NB/T34007-2012) completely.
To sum up, the utility model is for chimney over-emitting black exhaust during stove and accessory burning in the past, by the Curve guide impeller of biomass cooking heating stove, broken over-emitting black exhaust, this stove and accessory is by 2 air intakes, pernicious gas Thorough combustion, really accomplish that cigarette is walked from fire, efficiency of combustion is higher, and cooking heating is faster, there is unique super large storage bin, once feed in raw material and can use for a long time.This stove and accessory adopts low dust exhausting concentration, half vaporizing flow combustion technology, belong to half gasification combustion furnace, it is abundant that heat smoke washes away heating surface, improve stove and accessory combustion thermal efficiency, smoke medicining dust-removing effect be good, environmental protection and energy saving, cooking ability is strong, structure is unique, novel appearance, easy and simple to handle, once reinforced long-time continuous burning, not power consumption, noiseless, operation with no pressure, safe and reliable.Fuel and lime-ash totally-enclosed in fire grate and Dust Storage Room, in vaporizer, fuel gas is easy to abundant after-flame, really reaches the object of environmental protection and energy saving.
