Description
Technical field
The present invention relates to biological substance technical field of energy utilization, be specifically related to a kind of novel biomass solid shaping fuel and preparation method thereof.
Background technology
At present, in industrial boilers in China, coal firing boiler is occupied an leading position, and cheap fuel cost is a large advantage of industry coal-boiler.From many decades practical experience, coal firing boiler has 2 unavoidable drawbacks: one is that boiler thermal output is lower, and generally about 70%, fuel combustion is insufficient; Two is that blackness of exhaustion is large, and SO2, NOX content is high, and environmental pollution is serious.Along with country, government's energy-saving and emission-reduction measure are strengthened step by step, Shanghai City government implemented the reform of Energy-saving in Industrial Boilers work substituting coal firing boiler with fuel oil, combustion gas last year.How under government policy enabled condition, ensure that the economic benefit of self is current enterprise problem demanding prompt solution.Biomass molding fuel, as a kind of cleanliness without any pollution, reproducible environment-friendly fuel, is the high-quality fuel being adapted to enterprise's development.
Summary of the invention
The object of the present invention is to provide a kind of novel biomass solid shaping fuel, to solve the problem proposed in above-mentioned background technology, technical scheme is as follows:
A kind of novel biomass solid shaping fuel, comprises following raw material: wood chip 50-70 part, stalk 30-50 part, straw 5-15 part, Pericarppium arachidis hypogaeae 30-50 part.
The preparation method of above-mentioned biomass solid shaping fuel, comprises the following steps:
A, by raw material throw in disintegrating apparatus, carry out pulverization process;
B, by pulverize after raw material throw in fully mix to mixing equipment, mixing time is 5-15min;
C, to be fed through in drying plant by raw material mixed in above-mentioned steps to dry by supply line, bake out temperature is 70-90 DEG C.
D, the raw material after above-mentioned oven dry is fed through in extrusion formation equipment by supply line is cured shaping obtained finished product, and pack.
Further, described drying plant is revolution drying kiln.
Further, described biomass solid shaping fuel finished product is square or rectangular-shaped, and dimensions is 32mm × 32mm × 30-80mm, and density is 0.8-1.2g/mm3.
Further, finished product obtained in described Step d needs to be lowered the temperature by air cooler before pack, and the finished surface temperature after cooling is normal temperature.
Further, in described biomass solid shaping fuel finished product, moisture content is 15-20%, and ash content is 2.5-8, and rate of combustion is 85-92%.
Compared with prior art, the invention has the beneficial effects as follows:
1, biomass molding fuel fixed carbon content is low easily lights fast, and hydrogen, oxygen level are high, need not arrange flue gas desulfurization (FGD) unit, both reduced equipment cost during burning, additionally reduce SOX, NOX emission concentration in flue gas, are conducive to the protection of atmospheric environment;
2, biomass molding fuel ash content only has lower, is significantly less than the ash content of bunker coal, and the fuel combustion value of 1 ton of described biomass moulding is equivalent to the fuel value of 0.8-0.9 ton Industrial Boiler fire coal, is conducive to the efficiency of raising boiler and exerts oneself;
3, biomass molding fuel is hard-packed rod fuel, and storage, shipment are convenient, avoids occurring being similar to coal-fired this kind of bulk material and is scattered and the phenomenon of dust pollution;
4, the present invention adopts wood chip, stalk, straw and Pericarppium arachidis hypogaeae to prepare biomass raw material particle, and finished particle is fine and close, not loose, can long-term storage, and shaping biomass fuel pellet quality is closely knit.
