Discussion on preheating before mixture feeding
Thread Content
Our company’s 9-bar reduction furnace does not preheat the mixed gas coming from the vaporizer; it enters the reduction furnace directly. I’ve learned that many companies use reduced exhaust gases to heat the mixture, and I think this is a good approach – it makes full use of thermal energy. Preheating the mixture before feeding it into the reduction furnace is also beneficial for the reaction, and it should also result in energy savings. Let’s discuss whether 12-pair and 24-pair systems use this method; can the preheated mixture reach around 130 degrees? Let’s discuss this together.
The temperature of the reduced exhaust gases should not be controlled at too high a level; if it is too high, the amount of silicon tetrachloride will increase. However, this is different if you rely on the STC hydrogenation unit for the conversion process
Is an increase in STC related to reduced exhaust gases? ? ? I’m not quite sure; the reduction furnace is at around 1080 degrees, while the furnace walls are at 180 degrees. There must be some exhaust gas, right?
