The required thermal strength for coke is 60–64 or higher, but the results of each experiment are around 59 points, which is a difference of about one percentage point. How can CSR of coke be improved? Relevant professionals say that to increase the CSR of coke, it is necessary to raise the ratio of FM to JM. However, after the increase, the sulfur content in the coke became too high again. How can one have both fish and bear paws?
Improving the CSR of coke requires balancing multiple factors. Here are some suggestions: 1. Ensure the quality of coking coal: Choose higher-quality raw coal to achieve an optimal ratio of volatile matter to fixed carbon, which helps improve the CSR of the coke. 2. Pay attention to the gasification process: Parameters such as temperature, pressure, and gas flow rate during gasification need to be properly controlled to ensure optimal improvement in the physical and chemical properties of the coke. 3. Adjusting coke oven operating parameters: The quality of coke can be optimized by adjusting the operating parameters of the coke oven. For example, increasing the depth of the coke layer or extending the furnace residence time in the coke oven can have a positive effect on the CSR of the coke. 4. Identify and resolve other issues that may affect CSR: There may be other problems inside the coke oven, such as damage to the oven walls or blockages in the gas passages, all of which can impact the quality of coke and CSR. Timely repair and maintenance of these issues can improve the CSR of coke. In summary, improving the CSR of coke requires taking into account various factors such as coal quality, coke oven operation, and equipment condition, and making targeted adjustments and improvements based on the actual situation. At the same time, continuous monitoring and analysis are required to identify and address potential issues in a timely manner. .
The furnace temperature can be appropriately increased to extend the coking time
Is it effective to use lean coal? If so, it is recommended to replace 2-3% of it with lean coal, while raising the furnace temperature accordingly. But uniformity must be ensured
For Liugang, it probably uses a lot of coal from Guizhou, as there is an abundance of high-sulfur coal in the southwestern region. It’s not feasible to use 1/3 coke, gas, and lean coal of high-sulfur variety; instead, more low-sulfur coal, as well as coking coal and fat coal, should be used.
