The two-purpose furnace comprises a combustion device, a material storage device and a flue. The combustion device comprises the following components: a combustion chamber, a heat absorbing layer, a flame adjusting baffle wall, a fireproof layer, a heat insulation layer, an air feeding opening, an ash bucket drawer, a housing and a furnace cover. The material storage device comprises the following components: a material storage chamber cover, a material storage chamber, a water inlet, a water outlet, a heat absorption pipe, an explosion-proof valve and a fire grate. The combustion chamber is semi-cylindrical and has a flat bottom surface. The central part of the combustion chamber is provided with a flame adjusting baffle wall. One end of the flame adjusting baffle wall is connected with a heat absorption layer at the bottom surface of the combustion chamber, and the other end is separated from an arc top part of the combustion chamber for a certain distance. The material storage device and the flue are provided at a rear half part of the furnace. The material storage chamber and the chute are surrounded by a heat absorption layer. A flame outlet is provided between the lower part of the material storage chamber and the combustion chamber for intercommunication. A flue opening is provided between the lower part of the chute and the combustion chamber for intercommunication.
Description
Technical field
The utility model relates to a kind of domestic stove.
Technical background
Along with day being becoming tight of the energy, the rising steadily of coal price.Urban heating is progressively carried out central heating, and has obtained national subsidy, and in vast rural area, because the relative dispersion of living, the house warmth retention property is bad, and the winter heating expenditure is higher than the city far away, the ratio that accounts for peasant's total income is too high, causes rural area winter heating problem to be on the rise.Various in recent years novel energy-conserving stove and accessorys are also actively promoted in the rural area at this point, but effect is all not obvious.Simultaneously, the annual crops in rural area are reclaimed a large amount of stalk in back and burn in vain, cause the wasting of resources and environmental pollution.Be badly in need of that exploitation is a kind of to be utilized stalk or stalk and coal to mix to act as a fuel and possess the same continuous fiery function of coal stove, be fit to the stove and accessory that use in vast rural area, help the peasant to realize low-cost heating.
Summary of the invention
The utility model purpose is the deficiency that overcomes above-mentioned prior art, but provides a kind of stalk or stalk of using to act as a fuel, possess the same bottom ignition afterflame bavin coal cooking heating dual-purpose stove that continues fiery function of coal stove with the coal compound.
The utility model comprises burner, Storage appts. and flue; Burner comprises combustion chamber, heat-sink shell, accent fire screen wall, flame retardant coating, heat-insulation layer, air outlet, ash bucket drawer, shell and bell; Storage appts. comprises bin stock chamber cap, material storing room, water inlet, delivery port, endothermic tube, explosion-proof valve, fire grate.
Burner is positioned at the first half of stove, and the combustion chamber inner chamber is the flame retardant coating that the refractory material compacting forms, the about 10-15mm of thickness; The outside of flame retardant coating is a heat-sink shell, and heat-sink shell is the water interlayer that is interconnected, and also is interconnected between endothermic tube and the heat-sink shell; It is half-cylindrical that the combustion chamber is, and its bottom surface is the plane, is provided with one in the middle of the combustion chamber and transfers the fire screen wall, and transferring the fire screen wall is heat-sink shell, and profile is cuboid, and there is a concave arc mouth at the end face middle part, the convenient round bottom shape pot that uses,
Transfer fire screen wall one end to be connected with bottom surface, combustion chamber heat-sink shell, keep a determining deviation between the other end and the circular arc top, combustion chamber, this spacing is generally 100cm-150mm.Like this combustion chamber is separated into two parts from the centre, thereby forms the passage of a flue gas folk prescription to operation.Bell is at the end face of combustion chamber, and combustion chamber bottom is provided with air outlet.
Storage appts. and flue are positioned at the latter half of stove, and it is rectangular-shaped that material storing room and flue are altogether, and the volume ratio of material storing room and flue is roughly 2: 1.Adopt heat-sink shell to surround around material storing room and the flue, material storing room and flue all are higher than combustion chamber 60-80cm, increase the space of material storing room and flue, be convenient to store enough fuel for afterflame, the flue space is strengthened, then be in order to increase heat-sink shell and to arrange more endothermic tube, fully absorb the heat in the flue gas, reaching energy-conservation purpose.Be provided with crater between material storing room bottom and the combustion chamber and be interconnected, be provided with floss hole between flue bottom and the combustion chamber and be interconnected.The bottom of material storing room is a fire grate, and the fire grate bottom is the ash bucket drawer; The flue bottom lock communicates by floss hole and combustion chamber.The top of material storing room and flue top communicate by flue valve, and the flue upper end links to each other with chimney.
During burning, in material storing room, at first add kindling, draw back the ash bucket drawer, light a fire at the fire grate place, after igniting, in material storing room, add 1/3 fuel, cover bell, under the suction of chimney, flame is introduced in the combustion chamber through crater, under the effect of transferring the fire screen wall, flame forms eddy current and fully burns, and then enters flue through floss hole.In flue, endothermic tube absorbs the heat in the flue gas once more, effluxes at last.When reinforced, open the middle flue valve of flue, make the flue gas in the barrel enter flue, can not emerge, open the bin stock chamber cap, add material, cover the bin stock chamber cap from charge door through this gate, closed shutter, flame recovers in combustion chambers burn.When banking up a fire, fill it up with fuel, turn down the air outlet valve, build bell and get final product.During use, water in heat absorption water layer and the endothermic tube, the heat that produces when absorbing fuel combustion, temperature raises gradually, the characteristic of utilizing water to reduce gradually along with temperature rising density, and hot water up moves, cold water comes in to replenish, form Natural Circulation with the water in the radiator, heat is transmitted in the radiator, satisfy people's heating demand.
The utility model can use stalk or stalk and coal to mix and act as a fuel, and possesses the equally continuous fiery function of coal stove, and thermal efficiency height is convenient handy, is fit to vast rural area and uses, and helps the peasant to realize low-cost heating.
