Operating a hot oil heat transfer fluid system is not too hard when you know the basics

摘要

Operating a hot oil heat transfer fluid system can be easy if one understands the components of a system, how to start-up and shut-down the system properly and general operational procedures. Some other things that one should know are how to drain a hot oil system, how to recharge the system and the proper start-up procedure after recharging with new heat transfer fluid. This article will provide the basic knowledge needed to operate a hot oil heat transfer fluid system. System components and their function - The system is made up of a pump that pushes the heat transfer fluid though an insulated ridged or flexible piping system to a heater and to the process equipment. There is an expansion tank on the system to allow for the expansion and contraction of the hot oil as it heats up and cools down. To remove particulate from the system, some systems have in-line or side stream (preferred method) filtration units. The in-line filters 100% of the flow, where the side stream takes 10% or less of the system flow rate.
