What are the points of petroleum coke powder

Petroleum coke can be used as fuel, its calorific value is higher than that of coal; its volatile matter and ash are less than that of coal, but its moisture and sulfur are higher than that of coal, so it is often used to replace coal in cement kilns. According to statistics, about 38% of petroleum coke produced worldwide is used in the cement industry, and about 12% is used as fuel for industrial boilers. Taking a cement plant with an annual production capacity of 850,000 tons as an example, comparing the economic analysis of using 100% coal as fuel and using 50% of coal and 50% of petroleum coke each as fuel, the annual fuel cost can be saved by 18.6%, and the investment required for handling dual fuel can be recovered in about one year.
  
The combustion temperature of petroleum coke powder on the glass melting furnace reaches or is close to the flame temperature of heavy oil burning at 1650-1730 degrees. The ash content is the same as heavy oil and the sulfur powder is lower than coal tar. Then its petroleum coke is a product made from crude oil after separating light and heavy oil by distillation, and then heavy oil is converted by thermal cracking process. Petroleum coke components are hydrocarbons, which contain 90-97% carbon and 1.5-8% hydrogen, and also contain nitrogen, chlorine, sulfur and heavy metal compounds. Petroleum coke is the by-product of cracking the raw oil of the delayed coking unit at high temperature to produce light oil, the yield is about 25-30% of the raw oil, the low level calorific value is about 1.5-2 times of coal, the ash content is not more than 0.5%, the volatile content is about 11%, the quality is close to anthracite. If petroleum coke slurry is used as fuel in industrial production, because petroleum coke slurry contains about 30% water, 30% of the water should be absorbed and vaporized first when burning, which will greatly reduce the furnace temperature and increase the difficulty of fuel ignition; while the greatest advantage of petroleum coke powder and petroleum coke slurry is that petroleum coke powder fuel does not contain water, when burning, the calorific value of petroleum coke powder is much higher than that of petroleum coke slurry, which makes ignition easier and combustion It makes ignition easier and combustion more stable.
