煤炭在我国作为一次性能源在较长时期内仍占主导地位。但煤炭的燃烧也给环境带来了一定的污染。针对工业燃煤的污染,国家在脱硫脱硝和除尘方面均采取了一系列的处理措施。而生活用煤由于受传统制煤工艺等的约束,所产生的污染依然存在。传统的蜂窝煤制造工艺一直采用粘土作填充剂,但在煤炭燃烧过程中,粘土会吸收大量的热能而起到一定的阻燃作 Coal is still dominant in China as a one-time energy source for a long period of time. However, the burning of coal has also brought some pollution to the environment. For industrial coal-fired pollution, the state has adopted a series of measures in terms of desulfurization, denitrification, and dust removal. However, due to the constraints of traditional coal processing technology, the pollution produced by domestic coal still exists. The traditional honeycomb coal manufacturing process has always used clay as a filler, but in the coal combustion process, clay will absorb a lot of heat and play a certain degree of flame retardant.
