2), and the main cause that produces dioxin just is that the combustion process of most of materials (or mixture) can't rapidly increase to and can decomposes the temperature (wanting at least usually just can decompose dioxin more than 800 ℃) that dioxin or dioxin can't form, yet, treat that comburant is in the process of burning or incineration, temperature is higher owing to treat the outer rim of comburant to light, but the internal temperature for the treatment of comburant is lower than the outer rim temperature, moreover, if treat that comburant is the words of mixture, a plurality of different materials in this mixture have a plurality of different burning-points, the time point difference that takes fire will be caused, and can suck the lower air of ambient temperature in the process of burning, further hindering ignition temperature rises, cause incomplete combustion, temperature rises slower, and before rising to more than 1000 ℃, temperature caused a large amount of dioxin, thereby often incinerator must strict restriction burns the waste gas that is produced and still need continue to be detained and burn a period of time, and the dioxin that must further burn more than 99% just can discharge, and therefore existing combustion method or step are difficult to reduce the generation of dioxin; Moreover, because temperature inequality, incomplete combustion during burning, thereby cause that ignition temperature is lower, efficiency of combustion is lower, the heat that produces and obtain in the process is also lower, for example treat that comburant is coal, causes burning inhomogeneous owing to the coal internal and external temperature has difference when burning coal, chemical energy in combustion process is not converted to heat energy fully, and chemical energy partly then causes coal and other elements to produce chemical change and produce all cpds such as air-polluting dioxin and sulfur dioxide; In sum, have temperature in the existing general combustion process and fail fast rise, the differentiated disappearance of comburant inside and outside temperature.
Summary of the invention
Because above-mentioned the deficiencies in the prior art, the step that technical problem to be solved by this invention is a kind of pure material that burns is provided reaches the minimizing polluter whereby and produces and the more abundant advantage that chemical energy is converted to heat to promote efficiency of combustion, to accelerate the temperature rising.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of method that promotes efficiency of combustion, and being used to burn places a kind of pure material of a burning situation, and its step comprises:
A. judge the environment temperature of this burning situation, and set first temperature that is higher than this environment temperature;
B. this pure material is evenly heated to this first temperature;
C. provide a combustion-supporting gas also this combustion-supporting gas to be heated to one second temperature, this second temperature is higher than first temperature, and supplies with this combustion-supporting gas to this burning situation;
D. light this pure material.
Wherein this first temperature and second temperature are lower than the burning-point of this pure material;
This combustion-supporting gas is an oxygen; This combustion-supporting gas is the mist of multiple gases element.
The beneficial effect that the present invention can reach is: the present invention can be fast and this pure material that burns uniformly, but and ignition temperature fast rise, reducing the polluter rise time, and can pyrolytic part polluter, the generation of dioxin noxious material in the air can be reduced whereby.In addition, because this pure material can burn uniformly, make the most of chemical energy in this pure material combustion process can be exchanged into heat energy for the human use.
