The manufacturing method
of coke is
in the field of raw materials for chemical production. Coke is an important carbon material, which is widely used in iron and steel, non-ferrous metal smelting, chemical industry, electric power and other industries. The manufacturing method of coke mainly involves the high temperature dry distillation process, by controlling the ratio of raw materials, heating speed and temperature and other factors, can obtain stable quality coke products. In this paper, the manufacturing method of coke will be discussed in detail.

1. Feedstock Selection and Processing
The first step in
coke manufacturing is to select the appropriate feedstock. Generally speaking, the main raw material of coke is coal, which requires high volatile matter, low ash and sulfur, and good caking. In order to meet the production requirements, it is necessary to pretreat the raw coal, including crushing, screening, coal blending and other processes to ensure that the particle size and composition of the raw material meet the process requirements.

2. charging and heating

pretreated raw coal is charged into the coke oven. Coke ovens generally adopt continuous production mode, and the furnace body is divided into heating chamber, carbonization chamber and coke quenching chamber. The raw coal is loaded into the carbonization chamber from the top of the furnace and heated by the high-temperature gas in the heating chamber. In this process, the coal is subjected to high temperature, gradually softening, melting, gelation, and finally form coke.

3. dry distillation and coking

In the heating process, the volatile matter in the coal is gradually separated out, and the remaining fixed carbon is fused with the colloid at high temperature to form the main structure of coke. This process is called retorting or coking. In the coking process, it is necessary to control the heating speed and temperature to ensure the quality and yield of coke. After the coking is completed, the coke is pushed out of the carbonization chamber and enters the quenching chamber for cooling.

4. Coke Quenching and Screening

During the coke quenching process, the coke is in contact with water or air for cooling and extinguishing. The coke after coke quenching needs to be screened to separate the coke of different particle sizes to meet the needs of different users. The sieved coke product is packaged and stored for further use.

5. production control and optimization

In order to ensure the quality and yield of coke, it is necessary to monitor and optimize the production process comprehensively. By adjusting the ratio of raw materials, heating speed, temperature and other parameters, the quality of coke can be controlled. In addition, regular maintenance and overhaul of the equipment is required to ensure the stable operation of the production line.

6. environmental protection and resource utilization

coke production process will produce a certain amount of waste gas, waste water and solid waste. In order to protect the environment and improve the utilization rate of resources, it is necessary to take corresponding measures. For example, desulfurization and denitration treatment of waste gas to reduce the emission of air pollutants; purification treatment of waste water to achieve recycling; resource utilization of solid waste to improve resource utilization. Summary of

: The manufacturing method of

coke involves many links such as raw material selection and processing, furnace loading and heating, dry distillation and coking, coke quenching and screening. By controlling the production process parameters, optimizing the process and equipment maintenance, the quality of coke can be stabilized and improved. At the same time, strengthen environmental protection and resource utilization to promote the sustainable development of the coking industry.
