Automatic shutoff for sulfur melter apparatus |
摘要 |
A device for automatically shutting off a sulfur melter when its supply of sulfur is exhausted or when sulfur bridging has occurred is disclosed. The shutoff uses a temperature value sensed at the top of the melter's sloping melter bottom and shuts the heat off when the sensed temperature exceeds a preset value related to sulfur's melting temperature. The device avoids jamming and maintenance problems inherent in the use of mechanical level controls in a powdered/molten sulfur environment.
