Hello!
The coal utilization efficiency is generally 25-35%, and the coal utilization efficiency is only about 45%.
From the point of view of the article, it is about how to improve its utilization rate, make it burn completely and use its combustion heat.
1. Crush it to bring it fully into contact with air or oxygen.
2. Use waste heat to heat the air entering the combustion chamber
3. . Insulation;
4. Add oxygen.
etc.
The document also takes into account the increase in energy consumption of the equipment in order to improve its use efficiency. It is also necessary to eliminate the damage caused to the environment by coal burning.
