Description
Technical field
The present invention relates to bio-fuel technical field, more particularly to a kind of compound biomass granular fuel.
Background technology
Bioenergy due to its high energy, environmental protection, it is inexpensive, easy to use, renewable the features such as turned into the popular energy and ground
Field is studied carefully, by the common concern of countries in the world government and scientist.In states such as the U.S., Sweden and Austria, bioenergy
Using accounting for 4%, 16% and the 10% of the disposable energy-output ratio of the state respectively.Also the exploitation of bioenergy is attached great importance in China
And utilization, but current research emphasis is concentrated mainly on methane engineering technology, gasifying stalk central gas supply technology and garbage loading embeading
Generation technology etc., research and development, production for biomass fuel product and the research such as utilizes just to start to walk.
Biomass fuel is typically referred to by agriculture and forestry organic waste material, such as stalk, sawdust, bagasse, rice chaff, straw, rice husk, peanut
Shell, corncob, oil tea shell, cotton seed hulls etc. and " three surplus things " strip made from processing or block environmentally friendly new energy.Relative to biography
System fuel, biomass fuel have many technical advantages as a kind of regenerative resource：Purity height, small volume, burning-point are low, heating
Measure big, high combustion efficiency, cost is cheap, be readily transported, be easy to use, sulphur phosphorus content is extremely low, does not corrode boiler, will not cause acid
Extracting rate that rain, harmful gas emission are few, environmentally friendly, production environment sanitation and hygiene, ash are cut is low, the ashes after burning can be used as organic potassium
Fertilizer recycles, suitable for coal-burning boiler etc..
The above-mentioned advantage of biomass fuel obtains being widely recognized as energy field, and part research institution and enterprise are also right
It has been carried out the research of correlation and has achieved certain progress.For example, patent application " a kind of biomass fuel and preparation method thereof "
(CN201611207595.3) one kind biomass fuel made of corn stalk, straw, soybean straw, rice bran, sawmilling face is disclosed；
In another example patent application " a kind of biomass fuel and preparation method thereof " (CN201710411862.7) discloses one kind by fruit
The biomass fuel that skin, edible fungi residue, wood chip, attapulgite clay, straw, Chinese tallow seed slag composition are formed, has burning
The characteristics of efficiency high.
But also there are some problems during the promoting the use of of biomass fuel, due to the original of biomass fuel
Expect that burning-point is relatively low, and purity is higher, so its efficiency of combustion is universal very high, but incident problem be exactly burning velocity very
It hurry up, substantial amounts of heat can be discharged in a short time, for most of users, this feature of biomass fuel does not interfere with
Normal use, however, for being engaged in the user of finishing industry, often the thermal source lasting with greater need for stable exports, greatly
Calorimetric amount short time quick release can cause to produce the drastically rise of temperature, have a strong impact on the normal operation of its production technology, no
