In the countryside, almost no one is willing to burn smokeless coal for heating, but in the cement factory, coal is not a rare commodity.
Whether it's the rotary kiln using bituminous coal or the vertical kiln using smokeless coal blocks, both have strict requirements for the calorific value of the coal, as well as for the coal's ash content, volatile content, moisture, and sulfur content.
Every day, large trucks come and go from the cement factory, loaded with coal.
For this reason, Chen Zhou is not unfamiliar with high-quality smokeless coal.
This kind of coal has a much higher ignition point than lignite. If used at home, one needs to add wood to the furnace first, wait until the wood burns vigorously, and then add the coal.
