Abstract

The utility model relates to a filled bed type liquid fuel high-efficiency vaporizing combustion stove. A stove body is composed of a metal inner wall and a metal shell, and heat insulating material is filled between the metal inner wall and the metal shell. A filled bed is formed by granular fillers which are positioned in the stove. Symmetrical metal heat conducting sheets are arranged in the filled bed, and a transfusion device which is arranged on the side of a stove bottom is communicated with an annular transfusion channel in the stove bottom. The filled bed has the functions of capillarity and atomization, so that liquid fuel can be automatically inhaled and atomized; high-temperature fillers can accelerate vaporizing. Fillers which have certain chemical activity and catalytic action can be selected, so that fuel gas can crack to promote fuel gas to burn completely. The utility model has the advantages of high vaporizing efficiency, high combustion efficiency and low heat loss.

Description

Filled bed type liquid fuel efficience vaporizing combustion stove

The utility model is the efficient vaporization combustion stove of a kind of packed bed liquid fuel.

Present gas stove, most of coal gas and liquefaction vapour of using, but have the city of coal gas few, use liquefaction vapour comparatively general, supply falls short of demand to make liquefaction vapour, comparatively nervous, can not satisfy people's needs, thereby impel people to work out a kind of synthetic liquid fuel, this liquid fuel does not have pressure and is generally normal pressure, therefore how to make its vaporization and use under the normal pressure, become the key issue that synthetic liquid fuel is generally promoted.Existing synthetic liquid fuel stove, what have utilizes economizer bank with the preheating vaporization of liquid elder generation, could use then, the weak point of this structure is to have a preheating time, and mainly be that economizer bank uses after a period of time easily carbon deposit and with its obstruction, easy-clear does not cause cooking stove not use.The air bubbling that utilizes that has forms fuel-air mixture body and directly use, and this use easily produces the incomplete combustion phenomenon, and the thermal efficiency is difficult for improving.

The purpose of this utility model provides a kind of imbibition automatically under normal pressure, atomizing voluntarily, and it is fast to conduct heat, and furnace temperature is even, the efficient vaporization combustion stove of the packed bed liquid fuel of novel structure.

The utility model is achieved in that the body of heater of the efficient vaporization combustion stove of packed bed liquid fuel forms by being filled with heat-insulating material between metal shell and the metal inner surface, place the graininess inserts in the stove and form packed bed, in the middle of inserts, be provided with four or more metal heat transfer sheet, in the furnace bottom outside one or more transfusion devices are housed, it communicates with the ring-type transfusion raceway groove that is arranged on furnace bottom, thereby constitutes the efficient vaporization combustion stove of packed bed liquid fuel.

This combustion furnace novel structure, simple.Break through traditional structure, use the packed bed principle and design.Because the fine gap between the graininess inserts has capillarity, therefore normal pressure liquid fuel down can be sucked in the inserts automatically, and diffusion atomizes voluntarily rapidly, lights the heat after the burning, because the rapid heat transfer of metal heat transfer sheet and inserts, furnace temperature is risen immediately and be evenly distributed.Inserts under the high temperature is vaporized the liquid fuel of automatic suction rapidly, therefore this stove vaporization efficency height because the turbofan shape of metal heat transfer sheet places, makes combustion gas form strong eddy flow and fully mixes with air that stove central authorities enter and contact, impel sufficient combustion, the thermal efficiency is higher than present gas furnace.This stove is difficult for forming carbon deposit, also is easy to remove even carbon deposit occurs.Do not need preheating time after the igniting, can use.This stove cost is low, is easy to produce.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the structure chart of the efficient vaporization combustion stove of packed bed liquid fuel

Fig. 2 is the vertical view of above-mentioned stove

With reference to Fig. 1,2, the body of heater of the efficient vaporization combustion stove of inserts liquid fuel is formed by being filled with heat-insulating material (3) between metal shell (1) and the metal inner surface (2), it is fused by concentric inside and outside cylinder, inner cylinder is hollow, for the primary air air intake, place graininess inserts (4) in the stove and form packed bed, be certain slope above the bed.Inserts (4) can adopt the highly porous foam metal or the metal fiber polyporous material of sinter molding or adopt the not particulate powder with certain capacity of heat transmission of sinter molding, this gradient above packed bed can be with the topped typing of resistant to elevated temperatures wire netting, when in easy flights, can be not topped yet.Particulate powder can adopt iron, nickel, copper, zinc and powder of stainless steel etc., also can adopt metal oxide or sandstone with certain capacity of heat transmission to make inserts.Packed bed can adopt with a kind of inserts, also can adopt more than two kinds inserts to place by the performance layering, but the performance of based on fuel is selected for use.Have various fine gap between the whole inserts of this graininess packed bed, it has capillarity, the liquid fuel under the normal pressure can be sucked in the inserts automatically, and diffusion rapidly, liquid fuel is atomized voluntarily, help vaporization, igniting and burning.Inserts after the burning is in the condition of high temperature, it can make the liquid fuel of suction vaporize immediately, the metal dust that this vaporized fuel spreads between the high temperature inserts, rises owing to selects for use has certain catalytic action and chemism effect, can make long-chain combustion gas catalytic cracking become the short chain combustion gas, help burning fully, therefore this packed bed combustion furnace has the high advantage of vaporization efficency.In addition, it also has filtering efficiency.In inserts (4), be provided with four or more symmetrical placed metal heat transfer sheet (5), can adopt copper sheet to make, and put into certain inclination angle mutually and form turbofan shape, its effect: one is that heat transfer is risen furnace temperature immediately and is evenly distributed rapidly, one for to make combustion gas form strong eddy flow by turbofan shape, and the air that enters with stove central authorities fully mixes, and increase burning time, promote burning fully, improve the thermal efficiency.One or more transfusion devices (6) are housed in the furnace bottom outside, and its communicates with the raceway groove (7) of infusing of the ring-type in being arranged on furnace bottom, transfusion device (6) symmetrically and evenly cloth in the furnace bottom outside.It is made up of fuel valve (8), woven hose (9), adiabatic ring (10) and heat-insulated pipe (11), and heat-insulated pipe can adopt fiberglass pipe or earthenware or other heat-insulated pipes.It can make liquid fuel suck smoothly, can make heat not to external diffusion again.Ring-type transfusion raceway groove (7) can adopt metal porous pipe or wire netting to make.The course of work of this stove is as follows: open fuel valve (8), liquid fuel is because the capillarity of inserts (4) is drawn into inserts (4) surface automatically, ignition this moment, because the atomizing of inserts (4), combustion efficiency is pretty good, can use, flare can strengthen gradually, along with the rising of packed bed temperature is carried out in burning, and metal heat transfer sheet (5) heat transfer, furnace temperature evenly rises, by the chemism effect and the catalytic action of inserts, make that combustion gas is fully vaporized, cracking, reach clean-burning purpose.
