Problems solved by technology
In the chemical fertilizer industry, industrial boilers and civil fields, due to the inability to solve the thermal stability, a large amount of heat-wasting coal powder and coal ash are formed, and the anti-carbon rate is as high as about 30%, which pollutes the environment and wastes energy.

Embodiment
[0016] Embodiment: Get 25 kilograms of kaolin, 25 kilograms of silicate, 15 kilograms of aluminate, 15 kilograms of bentonite, 5 kilograms of gypsum, after pulverizing the above-mentioned raw materials at normal temperature, stir and mix with a mixing mixer to make a powder additive, It is added to 900 kg of coal dust, crushed, stirred, and finally shaped. The clean briquette produced does not need to be dried or aired, and is not afraid of rain and blisters. The finished product is kept the same as lump coal and can be used after 48 hours of curing.

Abstract
The present invention relates to a forming method of clean shaped briquet, its operation is simple and convenient, and the shaped briquet made by said method is high in thermal stability, good in activity, low in carbon-returning rate, and its cost is reduced, and the environmental pollution due to said briquet can be eliminated. Its process includes the following steps: using kaoling 25 kg, silicate 25kg, aluminate 15 kg, bentonite, 15 kg and gypsum 5kg, pulverizing them at normal temp., stirring and mixing them, and making them into powdered additive, and adding it into coal powder 900 kg, them stirring, and finally forming so as to obtain the invented clea shaped briquet.
Description
1. Technical field: [0001] The invention relates to a molding method of clean briquettes, which is mainly used in the fields of chemical fertilizer industry, industrial boilers, restaurants, canteen tea stoves and the like. 2. Background technology: [0002] my country is a large coal-producing country, and coal is the main energy source in the country. During the mining process of coal, 70% is coal dust, 30% is lump coal, and 20% to 30% coal dust is formed during the loading and unloading of lump coal, which not only wastes energy but also pollutes the environment. Therefore, people have been working on the development of fine coal briquettes for many years. The existing fine coal briquettes, such as carbonized briquettes, humic acid briquettes, pulp briquettes, and white peat briquettes, all have complex processes, low fixed carbon, and low cost. Problems such as large consumption and thermal stability cannot be solved. For example, the production process of carbonized b...
