Hot oil heating system
hot oil heating system diagram
Construction and control
1）oil furnace: heavy duty structure soldered with seamless structural steel, alumina silicate fiber for heat resistant, and high temperature cut-off valve embedded 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 heat and pressure resistance.
3）Professional high temperature hot oil pump, safe guarantee for long time no leakage working, inside which there are three oil circulation tubes to ensure the even heating.
4）Temperature control, PID control system
5）Pressure monitor: there’s pressure gauge on the tubes of the hot oil pump and the heating tube to reflect the real pressure inside the furnace, and it will give alarm to stop the heating when pressure 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, low pressure, low liquid level, etc.
8）Overall protection system: the protection system is based on chain reaction for the key parameters like liquid level, temperature, etc., any unnormal figure will trigger off the alarming system and react to stop the heating for overall protection.
