Abstract

The invention discloses a biomass fuel based on a sepiolite powder combustion improver and a preparation method thereof. The biomass fuel based on the sepiolite powder combustion improver comprises the following components by dry weight: 50-65 parts of sawdust, 20-35 parts of straw, 25-35 parts of returned sludge, 5-15 parts of attapulgite clay, 1-10 parts of a fluxing agent, and 5-15 parts of the combustion improver. The combustion improver, comprises, by weight, 40-60 parts of sepiolite powder, 10-20 parts of activated carbon, 5-10 parts of magnesium oxide, 4-8 parts of lanthanum nitrate, 2-7 parts of potassium perborate, 8-15 parts of fluorite, 2-7 parts of sodium bichromate, 1-6 parts of acetone, 4-8 parts of copper oxide, 5-10 parts of magnesium oxide, and 5-10 parts of calcium permanganate. The biomass fuel provided by the has a combustion temperature up to 1410-1520DEG C, combustion efficiency increased by about 30% than ordinary biomass fuels, a calorific value up to 5100-5200 kcal / kg, combustion tail gas in line with the relevant provisions of the state, a sulfur removal rate up to 94.3%, and a nitrate removal rate up to 94.8%.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a biomass fuel based on a sepiolite powder combustion enhancer and a preparation method thereof. Background technique [0002] For a long time, due to the low energy utilization efficiency and low combustion temperature of the direct combustion of agricultural and forestry wastes, its application range has been limited. The heating of various kilns in industrial production requires a lot of energy, which is a huge utilization market. However, the combustion temperature of the fuel is required to be above 1100 ° C, while the temperature of the traditional combustion method is only 600-700 ° C. The molded fuel of agricultural and forestry waste It is also difficult for the combustion temperature to exceed 1000 ° C, which cannot meet the requirements of industrial fuel quality; the conventional gasification and liquefaction fuels for agricultural and forestry wastes are expensive, and cann...
