Seeking advice on the gas temperature before the primary cooler

This post was last edited by LQ198619 on 2017-11-10 at 18:31. Dear experts, I’m not very skilled, but I have a question that has been bothering me recently; I hope someone among you can help answer it. The gas temperature before the primary cooler is generally specified to be around 82°C – so what is the lowest temperature it can reach? Won’t a lower temperature reduce the cooling load on the primary cooler? How about keeping it at 75 degrees? Is it harmful from aspects such as ammonia spraying and tar clarification?
If anyone knows, please help answer
What are the opinions of the DAPS experts?
Do you even charge a fee for asking such a stupid question? Is the OP mentally defective?
I’m sorry; I’m not very good at posting. I originally wanted to post a reward, sorry about that. But since you say the question is nonsense, that means you’re an expert on this topic. Could you please give me the correct answer? Ignoring the issue of ammonia temperature, I just want to ask whether it’s feasible to simply lower the temperature of the gas before the primary cooler
Low temperatures affect the fluidity of tar

The cooling of the gas is first carried out using circulating ammonia water in bridge pipes, gas collection pipes, etc., reducing the temperature from 700–800°C to around 85°C. If the cooling temperature is lower, it will increase the viscosity of the mixture of ammonia water and tar, making it easier for deposits to form within the pipes and cause blockages.
