Pressure retention issue in the reduction furnace
Thread Content
During normal production in the reduction workshop, there may be issues of a sudden increase in pressure inside the furnace. Please share the reasons why this phenomenon occurs in your daily operations! Additionally, the exhaust gas recovery system can also cause pressure buildup in the reduction furnace due to operational issues!
Issues such as the compressor shutting down due to recycling, and the abnormal operation of the outlet control valve (automatic shutdown) occur from time to time. However, what people encounter most frequently is the compressor shutting down, and in such cases it is necessary to evacuate the system urgently
1. The instrument air supply for the control valves in the subsequent process suddenly lost pressure. 2. The equipment is leaking, which triggers an immediate reaction and results in the production of a large amount of gas. 3. Pulsating fluctuations in the flow rate at the supply workshop.
The issues I encountered were: 1. Malfunction of the inlet and outlet control valves; 2. Shutdown of the CDI hydrogen compressor. The process in the workshop is relatively simple, mainly involving coordination with the raw materials department. The closed-loop design is interlinked, so any problem can affect the entire system
The pressure change in the reduction furnace is generally not significant. .
1. Fault in the reduction exhaust recovery system (caused by various factors: valve failures, hydrogen compressor failures, issues with the air supply for pneumatic control valves, and operational errors, etc.). 2. Fault in the reduction exhaust emission system (caused by various factors: operational errors, issues with the air supply for pneumatic control valves, etc.)
If there is a problem of pressure buildup in the reduction furnace, how should it be handled? Could you explain it in detail? I am extremely grateful!
I have encountered this situation before: first open the vent valve to release the fluid into your company’s venting system, and then close the feed valve
A safety valve should be installed on the exhaust pipeline, so that pressure can be released to the emergency venting system via this valve in case of pressure increases.
It might be that the exhaust pipe is not unobstructed. From your question, I can tell which company you belong to.
