Abstract
The invention discloses a cornstalk pellet fuel and a preparation method thereof. The preparation method comprises the following steps: 1) crushing the external soft shell of cornstalk into slurry and smashing the internal hard layer of the cornstalk and wood shavings into powder; and 2) fully mixing 5 to 10 wt% of the powder of the internal hard layer of the cornstalk, 60 to 65 wt% of the slurry of the external soft shell of the cornstalk, 15 to 20 wt% of wood shaving powder and 10 to 15 wt% of sawdust and carrying out extrusion so as to form cylindrical particles, wherein the powder of the internal hard layer of the cornstalk has water content of 10 to 12% by mass and a particle size of less than 5 mm, the slurry of the external soft shell of the cornstalk has water content of 15 to 25% by mass, and the cornstalk is the stalk of sweet corn, waxy corn, glazed corn or glass gem corn. According to the invention, the slurry obtained after crushing of the external soft shell of the cornstalk is mixed with the internal hard layer of the cornstalk, wood shavings and sawdust, so the pellet fuel is easy to shape and has a compact granule structure and high calorific value.
Description
Technical field
The present invention relates to the efficient utilization of the cornstalk quality of biomass energy, more particularly to a kind of cornstalk matter granular fuel and
Its preparation method.
Background technology
With expanding economy, the mankind are continuously increased for the demand of the energy, and the fossil energy such as coal, oil, natural gas
Source resource is just constantly reduced.Meanwhile, with the utilization of a large amount of fossil energies, pollution aggravates.Develop low stain, biomass can
The renewable sources of energy are into the focus of global concern.China all plants substantial amounts of cornstalk class plant, the combustion of cornstalk quality of biomass every year
Material extremely enriches, but fails for a long time to be utilized effectively.Shell arbitrarily abandons, rots, and has both caused biomass energy to waste, has made again
Into soil and pollution of waterhead.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of cornstalk matter granular fuel and its preparation side
Method.
Cornstalk quality of biomass granular fuel component be the cornstalk internal layer duricrust powder that percentage by weight is 5%～10%,
60%～65% cornstalk outer layer soft shell mud, 15%～20% wood shavings powder, 10%～15% wood sawdust.
The step of preparation method of cornstalk quality of biomass granular fuel, is as follows：
1) cornstalk outer layer soft shell is smashed into into mud first, cornstalk internal layer duricrust and wood shavings break into powder；
And then will be the cornstalk outer layer of cornstalk internal layer duricrust powder that percentage by weight is 5%～10%, 60%～65% soft 2)
Shell mud, 15%～20% wood shavings powder, 10%～15% wood sawdust are sufficiently mixed, and are squeezed into cylindrical particle.
Described cornstalk internal layer duricrust powder water content mass percent is 10%～12%, granularity<5mm；Described jade
Rice bar outer layer soft shell mud water content mass percent is 15%～25%.Described cornstalk be corn bar, waxy corn bar,
Coloured glaze corn or jewel corn.
The present invention is adhesive using cornstalk outer layer soft shell mud, it is not necessary to added binding agents, makes grain forming easily,
Closely, production cost is reduced grain structure.Made granular fuel caloric value reaches 17400J/g, during for gasification furnace, ash content
Few, gas production is big, and in combustion gas, tar content is few.Additionally, can be used for boiler instead fire coal, CO2 and SO2 discharges are reduced.
Specific embodiment
Cornstalk quality of biomass granular fuel component be the cornstalk internal layer duricrust powder that percentage by weight is 5%～10%,
60%～65% cornstalk outer layer soft shell mud, 15%～20% wood shavings powder, 10%～15% wood sawdust.
The step of preparation method of cornstalk quality of biomass granular fuel, is as follows：
1) cornstalk outer layer soft shell is smashed into into mud first, cornstalk internal layer duricrust and wood shavings break into powder；
And then will be the cornstalk outer layer of cornstalk internal layer duricrust powder that percentage by weight is 5%～10%, 60%～65% soft 2)
Shell mud, 15%～20% wood shavings powder, 10%～15% wood sawdust are sufficiently mixed, and are squeezed into cylindrical particle.
Described cornstalk internal layer duricrust powder water content mass percent is 10%～12%, granularity<5mm；Described jade
