The compound biomass fuel particle comprises 5-15wt% of straw, 20-35wt% of tree stem, 25-40wt% of bamboo sawdust, 20-40wt% of anthracite and 0.1-1wt% of an oxidant. The compound biomass fuel particle has a low water content and a high fuel value; and compared with common biomass fuel particles obtained after the compression molding of straws, the compound biomass fuel particle obtained through the formula adjustment and optimization and the synergetic combustion effect of coal and biomasses in the invention has the advantages of substantial improvement of the combustion efficiency, reduction of the ignition temperature, long combustion time, and no emission of harmful gases or acidic gases after the combustion.
Description
Technical field
The present invention relates to biomass fuel field, be specifically related to a kind of complex biological matter fuel pellet and preparation method thereof.
Background technology
The fuel major part that people use is at present the fossil energies such as coal, oil, Sweet natural gas, Nonrenewable resources, under the large-scale exploitation of the mankind, will peter out, and can in air, discharge a large amount of toxic gases when burning, to atmosphere, cause severe contamination, the mankind replace at the reproducible clean fuel of searching for this reason.
Biomass, as timber or agriculture and forestry organic waste material and coal mixed firing, both can efficiently be utilized refuse, can be reduced NO again
xdischarge.Because the nitrogen content of biomass is fewer than coal, and moisture makes combustion processes cooling, reduced NO
xthermosetting.While is because the activity of biomass is strong, and coal multifuel combustion demonstrates good synergetic property.
In the middle of existing technology, utilize often stalk, sawdust, bagasse, rice chaff and coal to be directly mixed to form a kind of compound biomass fuel; But in this biomass fuel, the point of ignition of stalk etc. is 300 ℃ of left and right, and the point of ignition of coal is more than 500 ℃.After easily causing like this stalk perfect combustion, coal does not but also have ignition, can not reach synergistic effect.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of synergy that has, a kind of complex biological matter fuel pellet of high combustion value.
Another object of the present invention is to provide the preparation method of this complex biological matter fuel pellet.
Technical problem to be solved by this invention is achieved by the following technical programs:
A complex biological matter fuel pellet, is comprised of the component of following weight percent:
Stalk 5 ~ 15%; Tree stem 20 ~ 35%; Bamboo bits 25 ~ 40%; Hard coal 20 ~ 40%; Oxygenant 0.1 ~ 1%.
Further, described tree stem is selected from palohierror stem.
Further, described palohierror stem is redwood stem, and its content of lignin is 20 ~ 28%.
Further, described bamboo to consider its content of lignin to be worth doing be 23 ~ 32%.
In biomass fuel, ignitable part is mainly Mierocrystalline cellulose, hemicellulose and xylogen; And the content of xylogen often has decisive role for the point of ignition of biomass fuel.Therefore in the present invention, have the selection raw material of gradient, making has different raw materials can play the effect of lighting at different point of ignition.
Biomass and burning of coal process are closely similar, can roughly be divided into that the separating out of preheating and drying, volatile matter, burning and coke form and burning, the after-flame three phases of residual coke.And biomass Exotherm ability is stronger, combustion processes mainly concentrates on early stage, and volatile combustion heat release has promoter action to the ignition of coal, burning, and combustion conditions improves.According to the feature of biomass combustion, in the process of Volatile burning, there is carbonization simultaneously, form the coke of hole prosperity, volatile combustion process and coal combustion process have overlapping part, both mutually promote, produce violent combustion phenomena, make biomass combustion speed apparently higher than coal combustion.
Further, described oxygenant is at least one in potassium permanganate, saltpetre, SODIUMNITRATE.
Adopt the method for adding oxygenant, changed the redox reaction of biomass, make point of ignition lower, the thermal discharge when thermal discharge of mixture pyrolysis-combustion processes is not used biological particles Individual existence apparently higher than this.
Further, described stalk and tree stem Han Shui Shuai≤8%.
Further, the Han Shui of described bamboo bits Shuai≤5%.
A preparation method for complex biological matter fuel pellet, steps of the method are:
A) weigh: stalk, tree stem, bamboo bits, hard coal, oxygenant are weighed in proportion;
B) pulverize: stalk, tree stem, bamboo bits in step a are pulverized respectively;
C) screening and oven dry: the powder body material that step b is obtained is dried respectively, and removes comparatively large vol simultaneously and pulverize incomplete component, control the water ratio of stalk, tree stem, bamboo bits;
D) mix: the components such as the stalk after drying in step c, tree stem, bamboo bits, hard coal, oxygenant are mixed by stirrer;
E) granulation: the components such as the stalk after mixing in steps d, tree stem, bamboo bits, hard coal, oxygenant are compressed into particle by granulator;
F) cooling: after particle in step e is cooling, to obtain described complex biological matter fuel pellet.
The present invention has following beneficial effect:
Complex biological matter fuel pellet water ratio of the present invention is low, fuel value is high, compare with the conventional biomass fuel pellet with straw compressing and forming, the present invention is by modulation and the optimization of formula, by the collaborative incendiary effect of coal and biomass, can greatly improve efficiency of combustion, reduce kindling temperature, and combustion time is long, after burning, there is no the discharge of obnoxious flavour, sour gas.
