Thermal oil heater in high temperature operation state, how to deal with a sudden power failure correctly?

FAQ

In the high temperature operation state of the thermal oil heater, if encounter the emergency of power failure, its correct handling method is:

When the circulating oil pump can not run normally due to power failure, the thermal oil in the furnace tube will exceed the allowable value in a short period of time due to the residual heat in the furnace chamber. At this time, the cold oil switching valve should be opened and the cold oil in the expansion tank should be released. And send it to the oil storage tank. At the same time need wet coal pressurization or emergency stop, need to be completed within 5 minutes.

Another thing to note is not to drain the oil in the expansion tank clean, otherwise the system will draw in air and cause problems. You can make oil level mark on the oil level of the storage tank. When replacing the cold oil, the valve can be closed in time to avoid the expansion tank and the oil storage tank from expanding.
