What is the reason that the temperature difference between the inlet oil and the outlet oil in thermal oil heater exceeds the given value?
(Question details) Specific performance:
The temperature difference between the inlet oil and the outlet oil temperature of the boiler exceeds the given value.
Answer:Cause of failure:
(1) The oil supply of the heat oil circulating pump is insufficient.
(2) The boiler operates overload.
(3) Thermal oil metamorphism.
(4) The boiler does not match the heating equipment.
(5) Bad insulation effect.
(6) There is gas or steam in the thermal oil.
Troubleshooting:
(1) Remove the faults of oil pump and pipeline.
(2) Operate at normal load.
(3) Change new oil.
