Description
Technical field
The utility model relates to the steam engine field, particularly relates to a kind of biomass fuel and electric dual-purpose steam generator.
Background technology
The development of BP particle
Biomass molding fuel (BIOMASS PELLET) (hereinafter to be referred as: be to use agriculture and forestry organic waste material (such as stalk, sawdust, bagasse, rice chaff etc.) as raw material the BP particle), by adding the efficient additive prescription, through the techniques such as pulverizing, extruding, oven dry, the high density of making, high-quality fuel particle.Be widely used in the auxiliary fuel of boiler of power plant, the alternative use of fossil fuel of Industrial Boiler in Europe, and home energy source supply and heating system.
The BP particle is to adopt high-quality wood chip, stalk as raw material, by adding efficient additive, through the techniques such as pulverizing, mixing, extruding, oven dry, a kind of Novel clean-fuel that can directly burn of granulation shape.
General agricultural crop straw, wood chip all have the shortcomings such as loose, that density is little, the calorific value of unit volume is low, act as a fuel that it is very inconvenient to use, and this is to cause people to be reluctant the one of the main reasons that acts as a fuel with stalk.The BP grain forming technique can not only address this problem effectively, and can effectively change the combustion characteristics of wood chip, stalk etc., realizes quick, clean combustion.
The BP grain forming technique is pressed into the close structure granular fuel with tangerine bar, agricultural wastes loose, in small, broken bits, before processing, its energy density wants about large ten times, this particle is convenient to storing, the cigarette ash of discharging and SO2 are a kind of high-grade fuel that Industrial Boiler uses that is suitable for far below coal after the burning.The BP particle can be regarded a kind of green coal as, is a kind of novel clean energy.
In the U.S., according to BPA(U.S. biomass power generation association) estimate, from 2010 to 2015, global biomass fuel market estimated to be increased to 6,937 hundred million dollars from 5,729 hundred million dollars, and annual average compound growth rate reaches 3.9%.Biomass fuel will develop into from 45,000,000,000 dollars in 2010 53000000000 dollars of the year two thousand twenty to the contribution of electricity market, the biomass power generation industry can produce 5 trils watt electric power hourly every year, 1.8 ten thousand job opportunities are provided every year, and remove 6,880 ten thousand tons the green rubbish of forest.
Along with the rise of energy prices with realize the target of energy-saving and emission-reduction, European Union promises to undertake the ratio of regenerative resource brought up to 20%, and the amplification in market demand every year of BP particle reached 20% in recent years.The demand that expects the year two thousand twenty BP particle will be brought up to from current 6,000,000 tons 4,000 ten thousand tons in Europe.Some countries of Europe have set up technical support and the project development company of policy, and have obtained the support of European Union's fund.
In European northern territory, the BP particle replaces the trend of traditional energy gradually to form, and substitution rate has reached 5%, and then under the energetically support of policy, substitution rate has reached 7% ~ 10% in the country such as Finland, Sweden, Austria.Biomass fuel pellet is mainly used in power supply and heat supply and cogeneration field at present.As the fuel of clean and effective, also the take like a shot method of supplying of this energy of resident family.The European maximum BP particle VIS NOVA GMBH of the factory production capacity that is positioned at Bremen, Germany reaches and reaches 180,000 ton/years.
Biomass energy is a rich ore of demanding urgently excavating in China.Take stalk as example, the stalk calorific value that China produced in a year is equivalent to 500,000,000 tons of standard coals.Expecting the year two thousand twenty, the discarded amount of national stalk will reach more than 200,000,000 tons/year, amount to 100,000,000 tons of standard coals, be equivalent to the producing coal amount in 1 year in coal Da Sheng Henan.
With biomass power generation with make the mode such as BP particle and can consume in a large number the discarded object that produces in agricultural, the production of forestry process, the ash content after the burning can with the form of fertilizer field also, be a benign circulation process of turning waste into wealth.The approximately 8000 tons of ashes that produce after the annual burning can be used as high-quality potash fertilizer direct returning to farmland.If utilizing the fund that drops into aspect the peasant family living beings with biomass power generation plant equivalent, can also create the nearly job opportunity more than 5 to 10 times for urban residents.
Biomass energy be applied in 11th Five-Year during namely obtained popularization, National Development and Reform Committee requires the year two thousand twenty to realize 20% carbon intensity reduction target and the long-range target that reaches this regenerative resource of 30000MW to the installed capacity of the year two thousand twenty biomass energy sources for generating electricity unit.Although more be subject to encouragement and the policy support of country by extensive investment construction biomass power plant, but because investment is reclaimed slowly, and because prices of raw and semifnished materials rise and expected fixedly raw materials requirement, cause present cost of electricity-generating high, and rate for incorporation into the power network adds subsidy and still can not make most of electricity power enterprise keep profit, the risk that also has simultaneously uncertain the price of international energy fluctuation to bring.
Near the area of the very abundant and reasonable price of 100 kilometer range endogenous substance resources biomass power generation is applicable.And BP particle factory can gather situation according to raw material to set up an office nearby because investment is little, thereby the living beings in the zone that biomass power plant can't relate to are fully developed.The particle of its production can be directly as the auxiliary fuel of power plant, reduce its discharge of poisonous waste, and can be by industrial to periphery, medical facilities make it successfully use biomass fuel with the transformation of boiler, in the rural area, transform the current thermal efficiency and only be traditional firewood range of about 10%, promote efficient high the biomass stove technology, promote household heating system, classified as one of key task of rural area new forms of energy construction by country, the exploitation of this technology mainly concentrates on two large fields, is the technological development of high-density biology matter fuel particle (BP particle) production technology and high-efficiency energy-saving stove on the one hand.
The Subject authority that the BP particle exists
At present domestic existing many enterprises are engaged in the processing business of BP particle, but enterprise comparatively disperses, and production scale is little, not yet forms industry size.And because raw material sources differ, being difficult to form quality standard, the particle processing dust burdening of many handicraft workshop formulas is larger, can not realize the efficiency of combustion of particle.
