Coke oven gas flows from the coke ovens to the chemical production section; after being cooled by the primary cooler, its temperature remains above 35°C. What causes the poor cooling effect? Are there any good ways to lower the temperature of the gas after the primary cooler?
There may be several reasons for the poor cooling effect of the primary cooler. One possibility is that the heat transfer tubes inside the primary cooler are blocked or corroded, preventing heat from being effectively transferred to the cooling medium and thus reducing the cooling efficiency. Another possibility is that the flow rate of the cooling medium is insufficient, preventing it from removing enough heat, which also results in poor cooling performance. Solutions to this problem include: 1. Inspecting and cleaning the heat transfer tubes inside the primary cooler to ensure they are unobstructed, and carrying out any necessary repairs or replacements. 2. Adjust the flow rate of the cooling medium; increasing the fluid velocity can enhance heat transfer efficiency. This can be achieved by changing the flow rate of the cooling medium or increasing its velocity. 3. Add a secondary cooler behind the primary cooler to further reduce the temperature of the gas. The secondary cooler can use different cooling media or other technical methods to enhance the cooling effect. 4. Examine and optimize the design of the primary cooler to ensure that its structure and dimensions enable effective cooling. The above are some common solutions; the specific one to be chosen and implemented should depend on the actual circumstances. .
