Abstract

The invention discloses a method for producing a high calorific value coal based fuel by using low calorific value coal, which comprises the following steps: taking 3 to 5 parts of potassium permanganate, 3 to 5 parts of potassium chlorate, 3 to 6 parts of calcined lime, 1 to 3 parts of potassium hydroxide and 1 to 3 parts of calcium chloride at the normal temperature and under normal pressure, and crushing the materials into granules of 80 to 150 meshes; and adding 5 to 10 parts of residual oil and 65 to 85 parts of low calorific value coal into the granules, and blending the mixture in a stirrer evenly. The method can effectively save the coal, improve the utilization rate of energy sources, reduce the emission of smoke dust and sulfur dioxide, and reduce environment pollution.

Description

technical field [0001] The invention relates to a method for producing high calorific value coal-based fuel by using low calorific value coal. Background technique [0002] my country is a country rich in coal resources. Coal is the main energy source in our country, accounting for more than 70% of the energy consumption structure. And with the decreasing reserves of petroleum resources and the development of new energy sources needs to be improved, the advantages of coal resources are becoming more and more obvious. [0003] More than 80% of my country's coal is used for direct combustion. Due to the relatively backward combustion technology and equipment, problems such as environmental pollution, low combustion efficiency, unusable part of low calorific value coal, and insufficient resource utilization have been caused. Problems such as acid rain and air pollution caused by coal burning have seriously affected the development and progress of our country and society. [0...
