Production and sales of 1.2 million kcal thermal oil boilers in the chemical industry by manufacturers

Description :

　　Thermal oil boilers often indirectly heat the controlled material/heat transfer medium through heat exchangers. Once coking and scaling occur, it will affect the heat exchange of the heat exchanger. If not cleaned, a lot of heat will be lost.

　　If carbon deposits and scaling occur, their harm is significant:

　　A small amount of light components in the thermal oil system are discharged through the exhaust line. Light components will cause low pumping flow and chain shutdown. The restructuring resulted in coking of the inner wall, increased temperature difference between the inside and outside of the furnace tube, burning through the furnace tube, and causing serious safety accidents. Pipeline coking or blockage must be cleaned.

　　Insufficient heat conduction can directly affect the quality of the product. The generation of coking and carbon deposition inside the heat transfer oil boiler can lead to excessive pressure loss in the furnace tube, and in severe coking, it can block the furnace tube; The surface temperature of the furnace tube rises. Due to the much lower thermal conductivity of the coking layer compared to steel, the thermal resistance increases in areas with coking, and the radial temperature gradient of the furnace tube increases. In areas with thick coking layers, hot spots appear on the surface of the furnace tube, affecting its service life; If the surface of the steel pipe is relatively rough, it will reduce the strength of the steel pipe and cause cracking accidents in the furnace tube.

　　⑶ Due to factors such as pollution, thermal degradation and condensation reactions, leakage from oxidation systems, residues, corrosion products, overheating, gel deposition, and small molecule volatilization, the viscosity, total acid value, moisture, and acetone insoluble matter of heat transfer oil increase. Low boiling and high boiling substances change rapidly, causing poor heat transfer rate, pump cavitation, high steam pressure, system overpressure, and pump seal wear, reducing the oil transmission capacity of oil pipelines, increasing frictional resistance, increasing transportation energy consumption, and sometimes even leading to accidents such as initial condensation and flow stoppage.

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

　　Therefore, after coking and scaling of the heat transfer oil boiler, it is necessary to clean it. And it is necessary to conduct regular tests on the viscosity, acid value, residual carbon, and flash point of the heat transfer oil. If the indicators are exceeded, it is important to clean the coking and carbon deposits inside the heat transfer oil pipeline.
