Seeking data on Klauss fans and controls

This post was last edited by ylb913 on 2016-7-3 06:36. For centrifugal fans, an anti-surge flow rate is usually set, which is controlled through venting. This is not a problem with the fan data itself, but rather an issue with the approach to process control. 1. There is a flow meter at the outlet of each fan, from where the flow goes either to the sulfur production furnace or to the vent; a valve is used to control this flow. It’s fine even if the valve leading to the sulfur production furnace is completely closed. In this way, if the air supply to the furnace is suddenly cut off in a chain reaction, the fan will not stop functioning. 2. Then, there is also a flow meter before the air-fed sulfur furnace, which is controlled by the flow control valve feeding into the furnace. 3. The other aspect is the setting of the chain valve. We have a interlock valve at the outlet of each fan (after the blowdown valve mentioned earlier), with the only interlock condition being a power outage of the fan. Then, there is also a interlock valve before the sulfur furnace; this is used for shutting down the plant, and there are quite a few interlock conditions.
