Saw dust compound environment-friendly fuel slug and preparation method thereof

Abstract

The invention provides saw dust compound environment-friendly fuel slug which is prepared from ingredients in parts by weight: 15 to 25 parts of saw dust, 25 to 35 parts of ethyl alcohol, 4 to 12 parts of potassium nitrate, 1 to 3 parts of manganese dioxide and 35 to 45 parts of paraffin. The invention further provides a preparation method of the fuel slug. According to the fuel slug, the saw dustis utilized to adsorb the ethyl alcohol; meanwhile, an oxidizing agent of the potassium nitrate and a catalyst of the manganese dioxide are added to support combustion. The fuel slug has the advantages of inflammability, high combustion heat, full combustion, long combustion time, small ash content, good combustion performance and use performance, no potassium nitrate generation after combustion,energy conservation and environmental friendliness; furthermore, residual ash after combustion can be recycled to prepare potassium fertilizer, and an effective cycle of waste saw dust-fuel-fertilizer is achieved. The invention further discloses the preparation method of the fuel slug. The preparation method has the advantages of simpleness, easiness in implementation and suitability for wide popularization.

Description

technical field [0001] The invention relates to a solid fuel, in particular to a sawdust composite environment-friendly fuel block and a preparation method thereof. Background technique [0002] With the development of the national economy and the increase in the number of automobiles, the problem of energy shortage has become increasingly prominent. The measures to develop new energy sources and realize multi-distance energy have attracted widespread attention from countries all over the world. The increasing tension of fossil energy has made the research and application of new energy more and more highly valued by various countries, and a large amount of funds and scientific researchers have invested in the research of these projects. Solid fuel is a substitute or supplement for conventional fuel, and it is a new type of fuel that emerges with the convenience and other special requirements of people for fuel. At present, my country's current annual output of agricultural ...

Problems solved by technology

At present, my country's current annual output of agricultural waste (straw, fruit shells, branches, wood chips, etc.) is about 600 million tons, equivalent to 300 million tons of standard coal, of which 53% is used as fuel, equivalent to about 159 million tons of standard coal, and these raw materials have not been effectively developed and utilized

[0003] The invention with the Chinese application number 2014102316757 discloses a biomass wood pellet fuel and a preparation method thereof, which includes 5 to 15 parts by weight of pine wood chips and 60 to 100 parts by weight of hard miscellaneous wood chips, and the hard miscellaneous wood chips are Two or more of oak wood chips, ash wood chips, ash wood chips, birch wood chips, elm wood chips, jujube wood chips, and oak wood chips. The biomass wood chip pellet fuel uses agricultural waste to improve resource utilization and meet energy conservation requirements. Environmental protection, but the fuel component is only wood chips, no oxidant and catalyst are added to support combustion, resulting in insufficient fuel combustion, low combustion calorific value, short combustion time and low thermal efficiency
