I have a question regarding heat loss
Thread Content
For a distillation vessel heated by heat transfer oil, with the temperature of the hot oil at 280°C and that of the material at 230°C, and taking heat losses into account, how many times should the heat provided by the hot oil system be the total heat required for evaporation?
The system has insulation; just give an approximate multiple
The pipeline is not long; it’s probably DN50, made of carbon steel, and 50 meters long

Approximately 70–80% of manufacturers produce heat transfer oil furnaces with low efficiency, while those of higher quality are said to have an efficiency of over 90%. You can calculate the heat load and then select a heat transfer oil furnace with the appropriate efficiency; pipes equipped with insulation result in very low heat losses. If the pipeline is longer, a larger heating device is required, and more heat may be lost; once the useful power is determined, multiplying it by 1.2 to 1.5 should provide sufficient heat. It’s best to ask the manufacturer of the heat transfer oil furnace you intend to purchase.
Thank you. No calculations have been done on the heat loss of the piping equipment, which is why this rather basic question was raised. Thank you for your help
