Hazard of coking in thermal oil heater

2019-01-08     Hits:3

  (1) Heat transfer oil due to pollution, thermal degradation and polycondensation reaction, leakage of oxidation system, residue, corrosion products, overheating, colloid deposition, small molecule volatilization and other factors lead to viscosity, total acid value, moisture and acetone insoluble matter increase, low boiling The material and high boilers change and the rate of change is large, causing poor heat transfer rate, pump cavitation, high vapor pressure, system overpressure and pump seal wear, which reduces the oil delivery capacity of the oil pipeline and increases the frictional resistance. Large transmission energy consumption, and sometimes even lead to accidents such as initial condensation and stoppage.

  (2) A small amount of light components in the heat transfer oil system are discharged through the exhaust line. Light components will cause low pump discharge and interlock shutdown. Heavy components can cause coking of the inner wall, increase the temperature difference between the inside and outside of the furnace tube, and burn through the furnace tube to cause serious safety accidents. Pipes that are cokeed or clogged must be cleaned.

  (3) Insufficient heat conduction will directly affect the quality of the product.

  (4) The heat transfer oil boiler must be cleaned before changing the oil. If the boiler is not cleaned, it will pollute the new oil, reduce its quality and shorten its service life.

  The heat-conducting oil boiler manufactured by Zhongzheng Boiler effectively prevents the coke deposits of the heat-conducting oil boiler through various technical means, and can be used by the users with confidence, and is highly praised by customers. Learn more
