Abstract

The utility model relates to a double helix efficient combustion home-use biomass furnace, belonging to home-use life furnace. The furnace takes biomass briquette fuel as main fuel. As the biomass fuel is renewable energy, the application research of the biomass fuel has important significance. Due to the furnace construction and air distribution design, the biomass furnace uses the twice air distribution structure with equidirectional turning direction and adopts a narrow long seam air distribution hole forming a certain angle with the radial direction of a hearth. First turning direction air distribution is positioned in the middle of a fire grate, and second turning direction air distribution is positioned along the circumference in the middle of the furnace body; an air duct of the second air distribution adopts a turning direction volute casing structure and is internally provided with an air deflector forming a certain angle with the radial direction, so that air distribution rotary motion is strengthened, the air distribution effect is reinforced, and the combustion condition of the furnace is improved; furnace fire and hot air take on a state of spiral rising motion. The combustible gas produced in the combustion process can be further mixed with the air for burning, thus ensuring the full-combustion. The life furnace has the advantages of high thermal efficiency, fuel conservation, convenient use, lightened labor intensity, convenient installation, low indoor environmental pollution and the like.

Description

Double helix efficient burning domestic biomass multifunctional furnace
Technical field:
The utility model relates to the domestic biomass multifunctional furnace, belongs to home-use household stove.
Technical background:
Biomass fuel has that calorific value is on the low side, firepower is strong, be easy to generate characteristics such as tar.When biomass fuel was used for the family life use, the tar problem polluted the environment, and is the indoor bad smell that has; Low and the not strong fast fiery cooking taste of problems affect of firepower of calorific value.If biomass combustion is insufficient, above-mentioned phenomenon is more obvious.Therefore the combustion position that improves home-use biomass fuel stove and accessory is a key issue.
Summary of the invention:
The utility model purpose of design is design and a kind of home-use efficient burning living beings multifunctional furnace is provided, this stove biomass burning shaped fuel, use for family daily life, satisfy heating and bathing fully with adding hot water function with solving the daily cooking need of work of resident, having concurrently.Usually, stove and accessory produces rising flame and thermal current from the fire grate bottom air inlet after the fuel combustion, and flame and thermal current do not have lateral movement.Some have the stove and accessory of secondary air distribution, and the secondary air distribution outlet adopts the circular hole along the burner hearth radial equipartition.The combustible gas stream undercompounding that secondary air distribution air intake and burner hearth burning form, influence is burning fully.The utility model has improved stove internal combustion situation by designing novel air distribution device, and an air distribution outlet of fire grate center adopts long narrow slit (seeing Fig. 1 and Fig. 3), and opening and angle w degree radially can make stove fire and hot gas present the screw state.The secondary air distribution outlet adopts long narrow slit (seeing Fig. 1 and Fig. 5), opening and angle w degree radially, inside, secondary air distribution road has and the uniform wind deflector (see figure 4) of angle w degree radially, the fuel gas that produces in the combustion process can with the further mixed combustion of secondary air distribution air, making the burning carry out more abundant.The domestic biomass multifunctional furnace partly is made up of the grey drawer of storage, fire grate dredging mechanism, air distribution outlet of rotation direction, burner hearth, rotation direction secondary air distribution outlet, fire sealing cover, water jacket, fire poking barrel, bell, heat absorption water ring, heat-absorbing water pipe, flue water jacket, flue, smoke evacuation heat-absorbing water pipe, heat-insulation layer, refractory masses, air distribution pipeline, blower fan, fire grate, gravity-flow ventilation mouth, controller of fan, fire door etc.
The utility model is used for the daily cooking of family, heating, bathing use, has following beneficial effect, advantage and characteristics:
1, reasonably air distribution design, furnace flame and hot gas present, spiral rising situation.
2, the fuel gas that partly gasifies fully mixes with hot-air in the spiral uphill process, burns once more.It is more abundant that combustion process is carried out;
3, during cooking, the stove fire burning is fierce, and caloric value is big, and firepower is strong;
4, thermal efficiency height, fuel saving;
5, sanitation and hygiene reduce indoor environmental pollution.
