If combustion process of the stove by the destructive distillation, cracking, gasification technology of fuel applied to stove, the destructive distillation of fuel, Gasification, cracking refer to the process of that fuel becomes gas, solid two-phase product from solid phase；Fuel gasification includes a series of physical, chemistry change Change, generally comprises dry, burning, gasification and cracking four-stage；Drying belongs to physical change, with the raising of temperature, fuel In moisture by thermal evaporation, other stages belong to chemical change, and burning is it is also assumed that be a part for gasification.Fuel is in burner hearth After middle drying, when being increased to 500 degree or more with the temperature in burner hearth, pyrolysis occurs for the molecule of fuel, generates big Volatile materials (including destructive distillation fuel gas, tar and pyrolysis water etc.) is measured, it is primary to thermally decompose when temperature reaches 900 degree or more Product is in contact with red-hot coke and high-temperature kiln wall, and secondary thermal decomposition occurs, and forms secondary thermal decomposition product, generates an oxidation The gaseous products as main component such as carbon, hydrogen, methane and carbon dioxide, nitrogen, hydrogen sulfide, water, i.e., thick fuel gas.Gasified reverse Should include many chemical reactions, the mainly mutual reaction of carbon, water, oxygen, hydrogen, carbon monoxide, carbon dioxide, wherein carbon with The reaction of oxygen is also known as combustion reaction, provide cracking, gasification heat.Product carbon monoxide, methane after second pyrolysis Through with gaseous materials such as hydrogen and collection, when high-temperature combustible gas body passes through burner body 7, with the combustion-supporting sky of high temperature by preheating It fully burns after gas mixing, while releasing a large amount of heat.So carry out high temperature of the fuel after destructive distillation, cracking, gasification , can be more thorough when burning, the impurity such as flue dust and tar are no longer contained in the flue gas after burning, flue gas is more environmentally friendly, clear It is clean.

Wherein, fuel tar thermal cracking processes are divided into three phases：First stage is from room temperature to 150 DEG C, is fuel coke The reaction of the precipitation of absorption water and volatile matter in oil, this stage meets four-dimensional diffusion mechanism, but since weight loss rate is slow, DTG Peak unobvious, this part are not major cleavage areas；Second stage is 150~430 DEG C, this process is polycondensation reaction, is mainly generated Object is methane, and ethane has a large amount of macromolecular tar to generate, reaches maximum value in 320 DEG C or so weight loss rates, this mistake in reaction The coke tar cracking of journey is that past heritage mutually disappear by random nucleation (n=4) mechanism, the nucleation stage that new object mutually generates, product Yield is small, and activation energy is larger needed for nucleation, activation energy 162kJ/mol；Phase III is 800~1150 DEG C, two during this Secondary tar cracks again, and it is mainly hydrogen and carbon monoxide to generate product, and the cracking reaction of this process is by three-dimensional diffusion machine Reason control, shows volatile gas and is cracked to form gas phase counterdiffusion and migration in reaction interface and phase region, and by temperature Degree influences significantly, and temperature is higher, and diffusion is stronger, and exacerbates the cracking of tar.

When reaction temperature is less than 700 DEG C, react between the carbon and vapor in the burner hearth of stove slowly, reaction The generation for being conducive to carbon dioxide, when temperature is higher than 800 DEG C, significant reaction is accelerated between vapor and carbon, and reaction is conducive to The calorific value of the generation of carbon monoxide and hydrogen, the vapour of generation increases.When temperature is less than 850 DEG C, back reaction mainly occurs, Carbon dioxide is difficult to be reduced；When temperature is higher than 850 DEG C, carbon monoxide increases sharply；When temperature is higher than 1200 DEG C, carbon dioxide Can Restore All are carbon monoxide.

Since tar is at high temperature gaseous state, it is thoroughly mixed with fuel gas, and (generally below 200 DEG C) are solidifying in low temperature Become liquid, the presence of tar there are various adverse effects to gasifying, it reduces gasification efficiency first, and tar produces in gasification The energy of object typically constitutes from the 5~15% of gross energy, this portion of energy is to be difficult to be utilized together with fuel gas in low temperature, greatly Part is wasted；Secondly tar is condensed into liquid in low temperature, and easy and water, coke etc. are combined together, and blocks exhaust and changes The passage of heat makes equipment operation occur difficult；In addition, the tar ratio gas for being condensed into fine drop is difficult to burn, hold in burning The particles such as carbon black are also easy to produce, this is greatly lowered the utility value of gasification burning.So the tar generated for gasification Characteristic, converted by superhigh temperature and it be converted into combustible gas, not only improve gasification efficiency, but also reduce the content of tar in combustion gas, Improve the utility value of fuel gas.In fuel hot-cast socket, the quantity of tar depends mainly on inversion temperature and gas phase stops It is time, also closely related with the rate of heat addition.For general fuel, at 500 DEG C or so, tar product is most, is higher or lower than This temperature tar is all accordingly reduced, and the composition of tar is extremely complex, and many compositions can be decomposed at high temperature.So with temperature The raising of degree, the quantity of composition is fewer and fewer in tar content, these tar compositions react, and generates carbon monoxide and hydrogen Equal gases had not only reduced the generation of carbon black, but also have improved the yield of combustible gas.

Stove of the present invention is designed based on above-mentioned principle, is that the destructive distillation, cracking, gasification technology of fuel are applied to stove The combustion process of tool, destructive distillation, gasification, the cracking of fuel refer to the process of that fuel becomes gas, solid two-phase product from solid phase；Fuel gas Change comprising a series of physical, chemical change, generally comprises dry, burning, gasification and cracking four-stage；It is dry to belong to physics change Change, with the raising of temperature, for the moisture in fuel by thermal evaporation, other stages belong to chemical change, burn it is also assumed that being A part for gasification；It is directly burnt using faggot stalk, using Combustion and thermodynamic principles, is suitable for countryside kitchen work heating Heating stove, for the stove a heatable brick bed in rural area, flue and Design of ventilation add Insulation and residual heat using device, improve heat Efficiency reduces discharge, and health is convenient, safety.
