The biomass solid fuel is prepared by pressing the following raw materials in percentage by weight: 90% of a biomass raw material and 10% of water, wherein the biomass raw material adopts crop derelicts, bamboo-wood processing residues or residual branches and leaves after timber cutting. The biomass solid fuel can replace coal, oil and other primary energy sources and serves as an alternative fuel; because the biomass solid fuel is a renewable energy source, the short supply of energy sources is alleviated; the biomass solid fuel is an environment-friendly fuel, and the combustion emission data reaches the national environmental protection standard, so that the pollution to the air is reduced, and the living environment is improved; and meanwhile, the biomass solid fuel is simple in processing technique, and the production process does not generate toxic substances and can not cause damages to the environment, so that the biomass fuel has an important significance for promoting the construction of a new socialist countryside.
Description
Technical field
The present invention relates to a kind of biomass solid fuel and complete processing thereof.
Background technology
Current, people's topmost fuel in life and suitability for industrialized production is coal, oil and gas, but these fuel the time can discharge objectionable impurities and toxic gas in burning, such as sulfurous gas, oxynitride, carbonic acid gas etc., and the serious natural ecological environment that destroying.China SO
290% of total emission volumn is produced by fire coal, and ecotope has been caused serious pollution.Simultaneously, along with the development of national economy and process of industrialization, the consumption of the energy day by day increases, and these fuel are disposable Nonrenewable energy resources, and long-term immoderate use has made the energy increasingly nervous.
Countries in the world cause enough attention to energy-saving and emission-reduction, constantly research and develop and clean energy is promoted the use of in call.In recent years, China also begins one's study gradually with the biological material new problem of fuel as an alternative, number be 200510076609.8 such as Chinese patent application, the applying date is on June 13rd, 2005, denomination of invention is a kind of economical biomass fuel (environmental protection charcoal) production method, its essence is exactly machine-made charcoal, by discarded biological material (such as sawdust, bamboo bits etc.) and the part ignition dope form, biological prepared material accounts for 95%, remaining is the chemical materials auxiliary agent, composition is that 3% degree Beaume is about 35 sodium silicate solution, and 2% technical grade sodium hypophosphite adds after above-mentioned materials mixed and uses.This product use-pattern is simple, and burning fully be adapted at town and country and utilize, but its ignition dope belongs to chemical products, still can produce poisonous, obnoxious flavour when burning.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of biomass solid fuel and complete processing thereof, take full advantage of China's agroforestry resource, with residual all wastes that can burn such as branch leaf after agricultural abandon, bamboo wood industrial wood waste or the trees felling, the method by the physics moulding is processed into and does not contain any objectionable impurities, reproducible biomass solid formed fuel.
Purpose of the present invention can be achieved through the following technical solutions: a kind of biomass solid fuel is formed by the raw material compacting that comprises following weight percent: 90% biomass starting material, 10% moisture; The biomass starting material adopt farm crop abandon, bamboo wood industrial wood waste or the rear residual branch leaf of trees felling.
