Problems solved by technology

However, there is no good method for drying coal briquettes to solve this problem.
Moreover, drying will also increase the production cost of large coal, resulting in waste of energy.
If the operation is not careful, it is also very easy to cause a fire hazard during the drying process
[0004] Moreover, the existing industrial briquette products have low sulfur fixation efficiency, and certain sulfides will still be released during the combustion process.

Abstract

The invention provides a sulfur-fixing type clean coal briquette which contains the following components by weight percent: 73%-80% of semi-coke, 4%-6% of coal briquette binder, 2%-3% of dehydrating agent, 0.3%-3% of coal briquette additive, 1%-2% of potassium manganate and 1%-3% of potassium permanganate, wherein the coal briquette additive is a mixture of potassium nitrate, potassium chloride, quick lime, sodium chloride and potassium perchlorate.

Description

technical field [0001] The invention relates to the field of molded coal processing, in particular to a sulfur-fixing clean molded coal and a preparation method thereof. Background technique [0002] Coal has been recognized as the cheapest energy source. The energy waste and environmental pollution caused by the direct combustion of raw coal are obvious to all. In order to change this situation, burning briquette coal, which is both energy-saving and environmentally friendly, is a must. Simple yet effective method. [0003] The use of briquette is a reform of the existing coal combustion. Compared with other coal fuels, it has advantages in all indicators, but the use of briquette has not been well promoted because it has a production bottleneck problem- -drying. In the process of briquette production, drying technology has become one of the important factors limiting the output of briquette. And the drying of coal briquettes does not have a good method to solve this pro...
