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 current people use is the fossil energies such as coal, oil, Sweet natural gas, Nonrenewable resources, to peter out under the mankind exploit on a large scale, and a large amount of toxic gases can be discharged in air when burning, cause severe contamination to air, the mankind replace at the reproducible clean fuel of searching for this reason.
By biomass as timber or agriculture and forestry organic waste material and coal mixed firing, both by refuse efficiency utilization, NO can be reduced again
xdischarge.Because the nitrogen content of biomass is fewer than coal, and moisture makes combustion processes cool, and decreases NO
xthermosetting.Activity simultaneously due to biomass is strong, and coal multifuel combustion demonstrates good synergetic property.
In the middle of existing technology, stalk, sawdust, bagasse, rice chaff and coal is utilized directly to be mixed to form a kind of compound biomass fuel often; But in this biomass fuel, the point of ignition of stalk etc. is at about 300 DEG C, and the point of ignition of coal is more than 500 DEG C.Like this coal after easily causing stalk perfect combustion is not but also had ignition, synergistic effect can not be reached.
Summary of the invention
Technical problem to be solved by this invention is to provide one and has synergy, a kind of complex biological matter fuel pellet of high fuel 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 kind of complex biological matter fuel pellet, is made up 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 considers its content of lignin to be worth doing is 23 ~ 32%.
Ignitable part mainly Mierocrystalline cellulose, hemicellulose and xylogen in biomass fuel; And the content of xylogen often has decisive role for the point of ignition of biomass fuel.Therefore in the present invention, there is the selection raw material of gradient, make have different raw materials can play the effect of lighting at different point of ignition.
Biomass and burning of coal process closely similar, can be roughly divided into preheating and drying, volatile matter precipitation, burning and coke is formed and the burning of residual coke, after-flame three phases.And biomass Exotherm ability is comparatively strong, combustion processes mainly concentrates on early stage, volatile combustion heat release, and have promoter action to the ignition of coal, burning, combustion conditions improves.According to the feature of biomass combustion, also there is carbonization in the process of burning in Volatile 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, change the redox reaction of biomass, make point of ignition lower, the thermal discharge when thermal discharge of mixture pyrolysis-combustion processes does not use 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 obtains is dried respectively, and removing comparatively large vol pulverizes incomplete component simultaneously, controls the water ratio of stalk, tree stem, bamboo bits;
D) mix: the component such as stalk, tree stem, bamboo bits, hard coal, oxygenant after drying in step c is 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) cool: after the particle cooling in step e, 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, compared with the biomass fuel pellet using straw compressing and forming of routine, the present invention passes through modulation and the optimization of formula, by the collaborative incendiary effect of coal and biomass, greatly can improve efficiency of combustion, reduce kindling temperature, and combustion time is long, after burning, there is no the discharge of obnoxious flavour, sour gas.
