The biomass fuels such as the various crop materials that have a large capacity and a wide range, faggot, biologic garbage are burnt because not reaching correct utilize
Burning or being embedded in the main reason for underground causes Heavy environmental pollution and resource significant wastage, produces this phenomenon is：Thermal power generation
Factory is higher than using above-mentioned matter fuel power generation function cost uses coal cost of electricity-generating, it is impossible to actively uses.Mai Chai specialists are because of stalk ratio
Heavy and light, volume is big, remote away from thermal power plant road, and cost of transportation is high, removes pickup, crushing, bundling and storage charges and uses, contributes not
Earn money.
600,000,000 tons of the annual output whole nation of stalk, only 100,000,000 tons to be used effectively.The straw-returning of makeshift, because not having
Two conditions of moisture content and temperature can not become organic fertilizer, and particularly northern drought, causes disconnected ridge and insect pest.Height extrusion block system
High temperature is needed into bar-shaped, block, granular.The conditions such as high pressure, adhesive, of high cost, price is higher than coke, and calorific value is only coke
1/3rd, user is difficult to receive, therefore the brand that boiler is turned on fired biomass fuel occurs, actually burn dissipate coal, be used for
Dosage is few at present for feed, gas making etc..
Should usage amount it is maximum be Industrial Boiler and the direct burning straw of heating hot water boiler, because of its convenient transportation, agriculture
The dispersible storage in family, is handled nearby, and plant ash is first-class environment-friendly fertilizer again.But because existing boiler combustion mode is restricted,
Direct combustion stalk does not reach completely burned, is also easy to produce blue smoke, tobacco, and environmental protection cannot be up to standard and cannot be used.Therefore crops straw
Stalk peasant does not have to burn in field on the contrary, and during three summer jobs three autumn jobs as harvesting, tilling and planting, county, small towns two-tier government are almost crew and set out, cadre
Village's fire prevention is wrapped, the time is every year for two months.
