Description

A kind of biomass energy-saving stove

Technical field

The utility model relates to the solid-fuelled household kitchen range of a kind of employing, specifically relates to a kind of biomass energy-saving stove.

Background technology

Publication number be CN201954592U patent document discloses a kind of firewood-saving stove, mainly comprise flue, the kitchen range top, stove, ash bin, grate and fire banking-up board, upper sealing panel is provided with in described stove, its center is provided with a port, a scalariform fireguard is fixedly connected with above upper sealing panel, it is arc, a vaporizer is provided with below upper sealing panel, multiple oxygen supply hole is provided with on body top, vaporizer room, an opening is installed at vaporizer centre bit, it is flexibly connected with brushwood inlet, brushwood inlet is provided with one, grate is provided with bottom vaporizer, sealing plate is provided with below grate, its center is provided with one and banks up a fire mouth, lower seal plate is provided with multiple hole, fire banking-up board is provided with below mouth of banking up a fire.This technical scheme combusting firepower is good, than tradition native stove saving fuel, but, remain deficiency have: one be kitchen range and cooker carry out heat exchange time, cooker is not high to the absorption rate of heat, and aflame high-temperature gas can not better be assembled close in cookware base, does not utilize cooker to absorb.Two be user be difficult to control well burner hearth to air quantity, often cause burner hearth for oxygen excess or deficiency, cause fuel unreasonable with the ratio of heating up in a steamer solution in the internal-combustion of thorax body, or combustible gas advanced combustion in thorax, or fuel-pyrolysis aerogenesis is not in place, the heat utilization efficiency of fuel can be reduced.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of biomass energy-saving stove, can improve the absorption rate of cooker to kitchen range place heat, with fuel saving; Reasonably can also control the air demand of burner hearth inside, make fuel reasonable with the ratio of heating up in a steamer solution in the internal-combustion of thorax body, combustible gas output capacity is high, and heat utilization ratio is high, good energy-conserving effect.

The technical solution adopted in the utility model is: a kind of biomass energy-saving stove, comprise kitchen range and stove body, kitchen range madial wall arranges flue, the range panel of central openings is set above kitchen range, in stove body, burner hearth is set, burner hearth upper port is communicated with kitchen range inner chamber, and fire-collection ring to be fixed on kitchen range base plate and to surround around burner hearth upper port; The thorax neck peripheral distribution of upper furnace has multiple inside and outside combustion-supporting hole, the thorax in the middle part of burner hearth offer feeding mouth with it and more than one inside and outside to pore, the thorax tail lower port place of lower furnace portion arranges movable sealing door, places fire grate in burner hearth cavity.

By the combustible gas of biomass fuel cracking, mix at neck place and combustion-supporting hole leaked-in air, spray from burner hearth upper port, enter kitchen range inner chamber vigorous combustion, produce thermal-flame, surround the stream condition that can change kitchen range inner chamber around the fire-collection ring of burner hearth upper port, thermal-flame is made to be gathered in cookware base, increase effective contact area of cookware base and flame flame envelope part, extend the holdup time of high temperature gas flow in cookware base, the absorption rate of cooker to heat can be improved, reach the object that fuel saving saves energy.

Movable sealing door sealing thorax tail lower port, the biomass fuel on burner hearth cavity fire grate is sent to by feeding mouth, air is provided from outside to inside by thorax pore of giving with it, support that fraction fuel combustion maintains higher furnace temperature, other most of fuel heats up in a steamer in high temperature state and solves combustible gas, and combustible gas is flowing through thorax neck place and mixing through combustion-supporting hole leaked-in air and export from burner hearth upper port, enters kitchen range inner chamber vigorous combustion, produce thermal-flame, release amount of heat.Be arranged on thorax with it give pore, the throughput of its ecto-entad can't by the impact of thorax tail lower port movable sealing door folding degree, also the impact of chocking-up degree can not be amassed by mirrnyong on the fire grate of burner hearth inside, therefore, when burner hearth normally works, the tolerance (oxygen-supplying amount) of giving of its burner hearth inner fuel generally all can be in the reasonable interval of setting, can not excessive also can not be not enough, fuel is in the internal-combustion of thorax body and the ratio of heating up in a steamer solution, all the time can maintain within the scope of the reasonable value of setting, the operating influence of user can't be subject to, thus it is larger by user's operating influence with the ratio of heating up in a steamer solution to overcome fuel combustion in known solution, usually be in unreasonable interval, combustible gas is advanced combustion in burner hearth, cooker is for the not high technical problem of the heat utilization efficiency of fuel.In the fuel ignition stage, movable sealing door can be removed, large quantity of air be flowed in furnace chamber from thorax tail lower port, rapid combustion-supporting raising thorax temperature, to be fired complete enter combustion phases after, reset movable sealing door sealing thorax tail lower port.

The ash bucket of drawer structure is set immediately below above-mentioned thorax tail lower port.Remove movable sealing door, the ashes of burner hearth inner accumulated can drop out from thorax tail lower port, fall in ash bucket, and user, by extracting ash bucket out, can collect cleaning ashes.

Above-mentioned ash bucket panel arranges total air door.Total airdoor control is by the gas supply flow of the external world to shaft inside, thus adjustable fuel combustion speed and flame size, use needs to adapt to user.

The utility model, by arranging annular fire-collection ring at kitchen range inner chamber, increases effective contact area of cookware base and flame flame envelope part, extends high temperature gas flow in the holdup time of cookware base, improves cooker to the absorption rate of heat; Pore is set to it by the thorax at burner hearth, fuel is maintained within the scope of the reasonable value of setting all the time in the internal-combustion of thorax body and the ratio of heating up in a steamer solution, most of heat that fuel produces is concentrated on release in kitchen range, be conducive to cooker to absorb, improve the effect that fuel saving saves energy.
