Heat form, electrical heating surface temperature are higher, and in cooling medium, long-play easily forms incrustation scale, and the presence of incrustation scale can enter one
Step increases heat transfer resistance, water resistance, deteriorates heat-transfer effect, finally causes electric heater dry combustion method failure；4）When electric heater is arranged on
During tank interior, once electric heater breaks down, need stoppage in transit valve cooling system to be overhauled, directly affect DC engineering operation
Stability and reliability, and heavy economic lossess will be brought；5）When electric heater is arranged on inside pipeline, due to being held by pipeline
Product affects, and heating is extremely uneven, though this kind of heat form is capable of achieving on-bne repair, need to increase maintenance valve before and after heater
Deng increasing and equipment cost and cause certain hydraulic loss.
