Could someone explain what the fundamental difference is between one furnace with two towers and two furnaces with three towers in coking? Apart from being more flexible and having higher efficiency, what are the differences in terms of coke quality and process control?

It is recommended to consult the proceedings of the 2010 China Delayed Coking Energy Conservation and Emission Reduction Technology Symposium: Advances in Delayed Coking Production Technology, 2010 edition, page 179; as well as Questions and Answers on By-product Production in Coking Plants (Second Edition), pages 179 and 180
Thank you! Do you have an electronic version? Could you send me one? 1505639210@qq.com
The main difference between the one-furnace two-tower method and the two-furnace three-tower method is that the one-furnace two-tower method uses a low-temperature coke oven to convert the heat absorbed by the coal powder into flue gas. The two-furnace three-tower process adds an additional tower, in which one of the high-temperature coke ovens is used to reheat the flue gas, thereby reducing the amount of heat absorbed by it and achieving higher overall efficiency. Furthermore, the two methods also have different effects on the quality of the coke produced: the one-furnace two-tower method and the two-furnace three-tower method involve distinct operating conditions for coke production; in particular, the two-furnace three-tower method allows for more effective control of the airflow in the coke oven, reducing the emission of pollutants from it and thereby improving the quality of the coke produced. If it’s useful, please like it; it would be even better if you gave money
