Where does the raw coal used in briquette production come from at present? How is it working?
I have tried it – using raw coal from Ningxia, Jincheng and Yangquan in Shanxi, Leiyang and Youxian in Hunan, Pingxiang in Jiangxi, and Liupanshui in Guizhou. The performance was worst with the coal from Yangquan in Shanxi, as its thermal stability did not meet the requirements. The lower the volatility of the raw coal, the better the quality of the briquettes. The coal from Youxian has a volatility level of only about 2%, which results in low gas production when used for gas generation. When choosing raw coal, it is necessary to take into account factors such as shipping costs and the intended use.
We’re from Jincheng, and the results are good.
The anthracite from Yangquan is of good quality; I’m not sure about the others
The fine coal of Jincheng, Shanxi, still has the best quality; we use the fine coal from there.
How is Pingxiang in Jiangxi? We are planning to go there to purchase goods

There is not much anthracite available in Pingxiang, Jiangxi; it has a calorific value of over 6,000 kcal/kg, a volatility content of around 6%, an ash content of 18%, and a sulfur content of 0.8%. The price is 730 yuan per ton. Anthracite with a calorific value of around 5,500 kcal/kg costs 670 yuan per ton; it has good reactivity and is easy to crush.
