Abstract
The invention provides a biomass briquette fuel. The biomass briquette fuel is formed by mixing biomass raw material particles with fuel additives, and then crushing, mixing, drying, extruding and granulating; the weight percentage of the biomass raw material particles is 90-95%; the weight percentage of the fuel additive is 5-10%; the biomass raw material particles are composed of saw dust, bamboo dust, straws and rice straws; and the fuel additives are composed of quick lime, a combustion improver and high clay. The biomass briquette fuel is low in dust content which is greatly lower than the dust content of the fuel coal, and also high in combustion value and advantageous for improving the efficiency and the output of a boiler.
Description
Technical field
The invention belongs to biological substance technical field of energy utilization, be specifically related to a kind of biomass molding fuel.
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, SO
2, NO
xcontent 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
For the fuel value solving existing biomass molding fuel is low, the problem that biological substance energy utilization rate is low, the present invention proposes a kind of biomass molding fuel, this biomass molding fuel biomass molding fuel ash content is low, be significantly less than the ash content of bunker coal, and fuel value is high, is conducive to the efficiency of raising boiler and exerts oneself.
Technical scheme of the present invention is achieved in that
A kind of biomass molding fuel, its mixed by biomass raw material particle and fuel dope after through pulverizing, mixing, dry and extrude pelletizing forming, the weight percentage of described biomass raw material particle is 90-95%, and the weight percentage of described fuel dope is 5-10%; Described biomass raw material particle is made up of wood chip, bamboo bits, stalk and straw, and described fuel dope is made up of unslaked lime, ignition dope and high clay.
Further, in described fuel dope, the weight percentage of each component is as follows:
Unslaked lime 15-25%;
Ignition dope 5-10%;
High clay 65-80%.
Further, described ignition dope is magnesite soil, magnesium nitrate, magnesium oxide or ferric oxide.
Further, described biomass molding fuel particle is shaft-like, and its cross-sectional diameter is 30-60mm.
Further, 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.
The combustion principle of biomass molding fuel of the present invention:
The combustible portion mainly Mierocrystalline cellulose of biomass molding fuel, hemicellulose and xylogen, combustion processes can be divided into following several stages:
(1), dehydration: the moisture in fuel is heated carburation by evaporation, overflows from fuel.
(2), the precipitation of volatile matter and burning: after fuel is heated, low-molecular-weight material first decomposition gasification, namely generates gas phase flame after arriving kindling temperature.
(3), transitory stage: now cellulosic thermal decomposition rate declines, and volatile matter material still can keep combustion flame.
(4), the surface combustion of coke: all carbonizations of the xylogen in fuel, the flame that Surface Creation radiance is hot.
Beneficial effect of the present invention:
1, biomass molding fuel fixed carbon content is low easily lights fast, and hydrogen, oxygen level are high, and volatile matter can reach more than 50% and be conducive to burning; In biomass molding fuel, sulphur content, nitrogen content seldom, need not arrange flue gas desulfurization (FGD) unit during burning, both reduce equipment cost, additionally reduce SO in flue gas
x, NO
xemission concentration, is conducive to the protection of atmospheric environment.
2, biomass molding fuel ash content only has about 5%, 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, bamboo bits, stalk and straw to prepare biomass raw material particle, the biomass fuel coagulation that with the addition of high clay is strong, be very significantly improved in pelletizing forming, finished particle is fine and close, not loose, can long-term storage, shaping biomass fuel pellet quality is closely knit, and the burning carbonate time is elongated, the structure of charcoal is also corresponding relatively tight, and the waste heat of charcoal burning also can fully be utilized.
