Description

technical field [0001] The invention belongs to the technical field of measuring combustion and sintering characteristic parameters of fine particle samples. Background technique [0002] Coal is the main energy source in my country, accounting for more than 65% of the total primary energy consumption. With the continuous increase of coal-fired power generation, it is estimated that coal-fired power plants produce more than 500 million tons of coal ash every year. The huge discharge of coal ash not only occupies a large amount of land and pollutes the environment, but also creates great pressure on the construction and development of our national economy. A large part of them have very good properties, and are mainly used in construction materials, road backfilling, chemical industry, etc., and have very broad application prospects and environmental protection value. Therefore, the rapid and accurate measurement of coal ash sintering characteristics and mechanism, and the a...
