WebSteam consumption may be determined by direct measurement, using flowmetering equipment. This will provide relatively accurate data on the steam consumption for an existing plant. However, for a plant which is still at the design stage, or is not up and running, this method is of little use. Thermal rating. The thermal rating (or design rating ... Weband the process heat transfer will become limiting. These equations show that the duty of a reboiler is con-trolled by varying the ﬂ owrate, W, of the heating medium (steam or thermal ﬂ uid). Alternatively, for a condensing medium, the duty may be controlled by back-ﬂ ooding the heat exchanger, thereby varying the area, A. The latter is how to stop keloid growth
