Abstract

The invention discloses renewable green biomass fuel. The biomass fuel is prepared from, by weight, 30-50 parts of wood processing residua, 5-18 parts of crop straw, 2-7 parts of bentonite compounds, 2-4 parts of methyl alcohol, 2-8 parts of isobutanol, 1-2 parts of ammonium nitrate, 1-2 parts of nonionic surfactant and 1-3 parts of fuel additive. The bentonite compounds are prepared as the following process: mixing and stirring bentonite and water, adopting a sulfuric acid solution to adjust pH value of the system to 3.4-4, adding a poly(diallyldimethylammonium chloride), stirring, filtering and cleaning the mixture, adding potassium carbonate and water, continuing to stir, filter and clean the mixture, drying the mixture to constant weight, grinding the dried mixture, adding and evenly blending soy protein and water, adding and evenly stirring sodium hydroxide at room temperature, adding maleic anhydride and then raising temperature and stirring the final mixture to obtain the bentonite compounds.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a renewable green biomass fuel. Background technique [0002] At present, coal-fired boilers dominate my country's industrial boilers, and low fuel costs are a major advantage of industrial coal-fired boilers. According to decades of practical experience, coal-fired boilers have two unavoidable disadvantages: first, the thermal efficiency of the boiler is low, generally around 70%, and the fuel combustion is insufficient; second, the blackness of the flue gas is large, and the SO 2 , NO x High content, serious environmental pollution. As the country and the government's energy-saving and emission-reduction measures are strengthened step by step, biomass briquette fuel, as a clean, pollution-free, renewable and environmentally friendly green fuel, is a high-quality fuel suitable for the continuous development of enterprises. How to prepare a biomass fuel with low nitrogen ...
