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.
The main sectors in which industrial steam boilers are used are:
Food, in industrial bakeries or baby food (as an example)
Textile, in rotary dryers
Chemical, for reactors or storage
Pharmaceutical, for the manufacture of medicines
Cosmetics, for the production of perfumes and creams
Stationery and printing, in drying tunnels
The cement industry, for the manufacture of cement parts
Oil, for the storage and distribution of heavy oils
Wood, involved in the process of melanin production
Hospitals and hotels, especially in the laundry and kitchen areas
Automotive and surface treatment, for the final metal finishing.
Question details (Performance):The steam pipe vibrates violently and has a dull impact sound.Answer: fault reason: There is air in pipeline ; automatic air vent valve is not turned on; or it is out of order. Troubleshooting: Check all the air release valves on the water supply pipe and the air release valves on the top of the boiler tube for gas storage. If the valve fails, it should be replaced immediately.
