Abstract

An isolation heating combustion furnace is usually used in everyday life and production. Since an absorption and conduction area of the wall of a combustion chamber is limited, the heat conduction efficiency is low, particularly when heating is carried out on air. High heat after combustion can not be completely absorbed to reach a required temperature, and the heat is discharged with the temperature being greater than the required temperature, so that the higher the required service temperature, the higher the smoke exhaust temperature of the furnace is; the smoke exhaust temperature is far higher than the room temperature outside the furnace, and serious temperature waste and environmental pollution are caused. The invention provides a combustion furnace which can improve the heat conduction efficiency substantially and recycle the smoke exhaust temperature very well. The combustion furnace adopts the scheme that the combustion chamber is provided with heat conduction boards; one end of each heat conduction board is placed in the combustion chamber and the other end of the heat conduction board extends out of the combustion chamber to reach the outer wall of a heating chamber; then heat exchange tube groups, surrounding the center of the combustion chamber in an arrayed manner, are arranged at the smoke exhaust front end; exhausted smoke and fresh air for combustion are subjected to counter-flow heat exchange to allow the temperature of exhausted smoke waste to approach to the room temperature outside the combustion furnace; and after the fresh air is heated, the fresh air enters the combustion chamber, and a better combustion condition is created for the combustion and a lower limit temperature is increased substantially.

Description

A kind of high-efficient energy-saving combustion aid

Technical field

The present invention is applied to application combustion furnace and gas or liquid is carried out isolate the various occasions of heating.

Background technology

In daily life, production, often application combustion furnace carries out isolation heating to desired gas or liquid, by firing in heating Burn chamber outer wall to required heating thing conduction heat energy, due to chamber wall absorb and conduction surface limited so that conduction of heat efficiency relatively Low, the heating to air is particularly evident.Because the high temperature after burning is not fully absorbed as temperature required, and it is more than required temperature Degree is discharged, and the temperature of required use temperature its smoke evacuation higher is higher, far above the outer room temperature of stove, cause very big temperature to waste and Environmental pollution.

Content of the invention

There is provided for the problem above present invention and a kind of conduction of heat efficiency can be greatly improved and exhaust gas temperature recycled Combustion furnace, implements as follows referring to accompanying drawing：

Fig. 1 is main body section view explanation

Fig. 2 is the A-A section view of Fig. 1

Method is to arrange thermal transfer plate 7 in combustor, and this thermal transfer plate one end is placed in combustor 6, and the other end extends burning Room forms to the outer wall of heating chamber 12, then around combustor center array, passes after during burning, a large amount of heat energy are absorbed by thermal transfer plate 7 Import the heating object in heating chamber 12（Liquid or gas）, the method depending merely on chamber wall heat transfer greatly improves and leads Thermal efficiency, thus reduce heat energy not fully absorb the problem just discharged.

Heat-exchange tube group 2,3 is set in waste gas discharge front end, after burning, the residuals temperatures after Assimilation and conductivity are led to waste gas Cross heat-exchange tube group 2,3 and carry out reverse flow heat exchange with burning fresh air, equal with institute waste discharge tolerance by entering resh air requirement, So that discharging EGT close to the outer room temperature of stove, and before fresh air is heated near waste gas discharge, temperature enters combustor participation combustion Burn, then the burning condition due to material and the relation of temperature, enter combustor after fresh air is heated and create preferably to burning Burning condition and increased higher rebasing temperature, the temperature after thus burning almost all is heated interior heating object and inhales Receive, thus greatly improving the efficiency of combustion furnace.

Process is to enter fresh air by fresh air inlet 1, flows downwardly into bottom along the pipe outer wall exchanging pipe group 2 and turns to exchange pipe group 3 pipe outer wall enters in combustor 6 through fresh flue 4, grate 5 upwards and participates in burning, during with exchange pipe group 2 and exchange pipe group 3 pipe in arranged burning waste gas reverse flow and be heated near the EGT before discharge.Temperature after burning passes through heat Guide plate 7 conducts the heating object to heating chamber 12, and the bottom of heating chamber 12 is provided with the entrance 10 of heating object, and top sets Put heating object outlet 11 and be easy to heating object circulating-heating.After burning, the residuals temperatures after Assimilation and conductivity enter with waste gas Pass downwardly through decompression disposal box 8 in the pipe of heat-exchange tube group 3 to flow in the pipe of heat-exchange tube group 2, more upwards by exhaust opening 9 row Go out, during be cooled to outside stove normal with exchanging pipe group 3 and outer the entered fresh air reverse flow of pipe that exchanges pipe group 2 Temperature.
