The Theoretical Calculation of Heating of Rail Oil Tank Car in Its Hydraulic Cleaning

The heat transfer processes, in which hot air, hot water and steam are utilized to heat up oil rail tank car respectively, are studied in the hydraulic cleaning of rail oil tank car. Formulas that describe the variation of temperature of rail oil tank car with time are inferred. These formulas provide a theoretical basis for the making out of heat technique of using portable cleaning equipment to carry out cleaning process.
