Abstract
The utility model provides a domestic coal stove which can decrease coal consumption and environmental pollution, comprising a stove casing, a liner, a stove plate, a grate, a combustion chamber, an air inlet chamber, and an air intake valve. A heat-insulating layer made of asbestos is filled among the stove casing and the made from high temperature refractory material, the liner, the stove plate, and the grate. A plurality of ventilation through holes are arranged on a stove casing wall.
Description
The utility model relates to solid-fuelled domestic burners, particularly a kind of domestic briquet stove.
In the existing briquette stove, the heat that briquette is produced when burning in the combustion chamber is except passing to cooker, have quite a few heat to be dispersed in the ambient air through furnace shell and stove plate, not only cause the meaningless waste of heat energy, the waste gas of its corresponding generation, waste residue have also increased the pollution to environment.
The purpose of this utility model will provide a kind of improved domestic briquet stove.This coal stove can prevent that the heat in the combustion chamber is meaningless lost, and reduces the pollution to environment.
Task of the present utility model is finished as follows.
A kind of domestic briquet stove, comprise furnace shell, flue, stove plate, fire grate, combustion chamber, inlet air plenum and air intake valve, its characteristics are to be filled with between furnace shell that high-temperature refractory is made and flue, stove plate, the fire grate thermal insulation layer of asbestos material, and described furnace shell wall is provided with some ventilative through holes.
The asbestos insulation layer thickness of the utility model domestic briquet stove can be 2-10 centimetre.
Can be evenly equipped with some ventilative through holes on the furnace shell wall outside the utility model domestic briquet stove insulating layer of asbestos.
The utility model domestic briquet stove is owing to be filled with insulating layer of asbestos in the space that furnace shell, flue, stove plate, fire grate surround, the heat that produces when therefore briquette burns in the flue inner combustion chamber is by in the combustion chamber of insulating layer of asbestos retaining in flue, its heat all directly offers cooker basically, so the heat energy dissipation amount is very little.Through test, compare with common coal stove, use continuously and can save about two of briquettes in eight hours, every briquette can boil water about 8 bottles.Because coal consumption reduces also the pollution that has reduced waste gas, waste residue to environment with regard to corresponding.
Below with reference to accompanying drawing structure of the present utility model is described in further detail.
Fig. 1 is the vertical view of the utility model domestic briquet stove.
Fig. 2 is the front view of the utility model domestic briquet stove.
Fig. 3 is along the organigram of analysing and observe of A-A line among Fig. 1.
Consult Fig. 1-Fig. 3, the utility model domestic briquet stove comprises: with furnace shell 1 and the flue 2 that the high-temperature flame-proof material is made, the high-temperature flame-proof material can adopt basic refractory to be the ceramic composition of base-material and to produce furnace shell and the moulded products of flue.Stove plate 3 and fire grate 4 are Cast Iron Products, and the inner chamber of flue 2 constitutes combustion chamber 5.In the furnace shell 1, the below of fire grate 4 constitutes inlet air plenum 6, and the furnace shell wall around the described inlet air plenum is provided with air intake valve 7, and described inlet air plenum is double as storage cinder chamber again, and described air intake valve port is double as ash discharge cinder notch again.Be filled with insulating layer of asbestos 8 in the space that described furnace shell, flue, stove plate, fire grate surround, described insulating layer of asbestos also can be prefabricated into cylindric insulating layer of asbestos by the shape size in described space, can conveniently install or change like this.The outer furnace shell wall of described insulating layer of asbestos is provided with ventilative through hole 9, be after the moisture in the rising of flue temperature, the insulating layer of asbestos is heated vaporization, can be dispersed in the atmosphere on every side in the purpose that ventilative through hole is set on the furnace shell wall through ventilative through hole 9, can avoid furnace shell and flue to produce the crack like this, to prolong the service life of domestic briquet stove.Particularly time spent or absorb in intermittent drizzles in the rainy season seasons, insulating layer of asbestos under the situation than juicy not coal stove long period, if do not establish ventilative through hole on the furnace shell, then when furnace temperature raises, escaping gas is easy to make furnace shell to chap in the insulating layer of asbestos.Described ventilative through hole can uniformly be provided with on the furnace shell wall, can make like this to breathe freely evenly, helps protecting furnace shell.Can be provided with perpendicular rib 10 on the inwall of flue 2, described perpendicular rib structure can improve the ventilation condition of combustion chamber, in order to the abundant burning of briquette.
Claims (3)
