Background

Petroleum coke is black solid coke which is formed by cracking and coking vacuum residue of crude oil at 500-550 ℃ through a delayed coking device, and is a byproduct in the production of light oil products. The volatile content of the petroleum coke is about 10-18%, and the low-level heating value is more than 8000 kcal/kg. Therefore, the petroleum coke as a solid fuel has higher application value in the production practice of inorganic nonmetallic material products such as glass, cement, refractory materials and the like.

Generally, petroleum coke after delayed coking needs to be cooled by water spray, and the cooling process directly causes the moisture content of the petroleum coke to be as high as 8-12%. The conventional drying equipment can only reduce the moisture in the petroleum coke to about 3 percent, and the high moisture in the petroleum coke is not beneficial to the grinding of the petroleum coke powder-making process and the pneumatic transmission of the petroleum coke powder in a fuel pipeline.
