Sepiolite based biomass fuel and preparation method thereof

Abstract

The invention discloses a sepiolite based biomass fuel, which comprises the following components by dry weight: 50-100 parts of agricultural and forestry waste, 50-100 parts of sawdust, 5-9 parts of pulverized coal, 10-20 parts of an anti-slagging agent, 20-40 parts of pine needle, 4-8 parts of potassium chlorate, 3-7 parts of gasoline, and 20-30 parts of a combustion supporting agent. The combustion supporting agent comprises the following components by weight: 60-80 parts of sepiolite powder, 40-60 parts of basic cupric carbonate, 30-50 parts of heavy calcium carbonate powder, 40-60 parts of sodium nitrate, and 10-16 parts of manganese oxide. The low cost and high temperature energy provided by the invention can meet the temperature requirements of most industrial heating and kiln fuels.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a sepiolite-based biomass fuel and a preparation method. Background technique [0002] Agricultural and forestry waste is a large amount of waste generated during the harvesting and processing of agricultural and forestry crops, such as the straw left in the farmland when the crops are harvested, the rice husks and bran left in the agricultural production process, and the branches and leaves in the forestry production process. , wood chips and leftovers from wood processing, as well as residues discharged from the food processing industry. my country is rich in agricultural and forestry waste resources. At present, agricultural and forestry wastes are scattered loosely in a large area. Except for a small part of crop straws used for livestock feed, cooking and heating, most of them are discarded as waste in the fields. There are many ways of utilizing agricultural and forestry wastes, ...

AI Technical Summary

Problems solved by technology

However, 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 The combustion temperature is also difficult to exceed 1000°C, which cannot meet the requirements of industrial fuel quality; the conventional gasification and liquefaction fuels for agricultural and forestry waste are expensive, and cannot meet the requirements of industrial fuel economic indicators

Therefore, the 700 million tons of straw and 200 million tons of forestry waste produced in our country every year cannot enter the market of industrial kiln fuel, which is suitable for the characteristics of biomass dispersion. Most of the straw is burned in the field, causing pollution and accidents, and litter and weeds are allowed to rot, which not only causes environmental pollution, but also cannot utilize resources, resulting in a serious waste of resources
