How should the pore size of the high-pressure ammonia water nozzle in the coke oven bridge tube be designed? :I’d like everyone to share their opinions on the handshake issue. In our company’s design, smoke guidance is achieved using smoke guide vehicles. For the side furnaces, it’s not possible to use two adjacent smoke guide holes as in the case of the central furnaces; only one hole can be used for this purpose. If the ammonia pressure required for the central furnaces is sufficient to facilitate smoke guidance, then it may not be sufficient for the side furnaces. Personally, I think the diameter of the high-pressure ammonia holes in the side furnaces could be increased to boost the flow rate of ammonia during smoke guidance. But how should this be designed? By how much should it be increased? What impact will the space at the top of the furnace and the air flow resistance of the smoke guide sleeve have? At present, the high-pressure ammonia nozzles used in our company are of the single-spiral type, with a pore diameter of 7 mm. We would appreciate some guidance from experts
