Hot oil heatingsystem
hot oil heatingsystem diagram
Construction andcontrol
1）oil furnace: heavy duty structure soldered with seamless structural steel,alumina silicate fiber for heat resistant, and high temperature cut-off valveembedded between the furnace and the oil pump.
2）Electric heater: flanged heater with heating tube made of 1Cr18Ni9Ti,heating wires made of Cr20Ni80, and filler of magnesia powder, with high heatand pressure resistance.
3）Professional high temperature hot oil pump, safe guarantee for long timeno leakage working, inside which there are three oil circulation tubes toensure the even heating.
4）Temperature control, PID control system
5）Pressure monitor: there’s pressuregauge on the tubes of the hot oil pump and the heating tube to reflect the realpressure inside the furnace, and it will give alarm to stop the heating whenpressure goes unnormal.
6）Liquid level monitoring: there’s monitoring system for the liquid level,and it will give alarm to stop heating when the liquid levels down.
7）Key alarming system: audible and visual alarm for overheating, lowpressure, low liquid level, etc.
8）Overall protection system: the protection system is based on chainreaction for the key parameters like liquid level, temperature, etc., anyunnormal figure will trigger off the alarming system and react to stop theheating for overall protection.
