In the case of a thermal oil heater that is in a high-temperature operation state, how should it be handled correctly in the event of a sudden power failure?

06 Dec 2019

In the case of a thermal oil heater in a high-temperature operation state, if it encounters an emergency situation of power failure, its correct treatment is:

When the circulating oil pump cannot operate normally due to power failure, the heat transfer oil in the furnace tube will exceed the allowable value in a short time due to the residual heat of the furnace. At this time, the cold oil switching valve should be opened to release the cold oil in the expansion tank. And sent to the oil storage tank. At the same time, wet coal pressure or emergency shutdown is required and needs to be completed within 5 minutes.

In addition, we need to pay attention to not to put the oil in the expansion tank clean, otherwise the system will inhale air and cause problems. An oil level mark can be made on the oil level of the oil storage tank. When the cold oil is replaced, the valve can be closed in time to avoid the expansion of the expansion tank and the oil storage tank.
