The international organization for standardization stipulates that dust is defined as a solid suspension having a particle size of less than 75 μm. The presence of dust in the atmosphere is one of the main causes for maintaining the earth's temperature, and too much or too little dust in the atmosphere can have a catastrophic effect on the environment. However, in life and work, productive dust is a natural enemy of human health and is a major cause of various diseases.
Dust has some energy as does other substances. The surface energy of the dust is also increased due to the small particle size and large surface area of the dust. One coal with the weight of 1g has the surface area of only 5-6 c square meters, while 1g of coal dust can float, and the surface area can reach 2 square meters. The dust is mixed with air to form combustible mixed gas, if the dust meets open fire or high-temperature objects, the dust is easy to catch fire, the burning process is finished in a tilting room, a large amount of heat energy is released, the burning gas is suddenly raised, the volume is violently expanded, and high expansion pressure is formed.
