Fired heaters use the heat generated from fuel combustion to heat up process fluids contained in the coils of a heater vessel. A heater can be designed to a direct heating type where the process medium flowing in the heating coils is heated directly. For indirect heating, the heater heats up the Heat Transfer Medium (HTM) which is then circulated to heat up the process; like heating coils in the tank or providing heat source for a heat exchanger.
DFINITI’s fired heaters are designed and constructed according to industrial standards such as API 560 (ISO 13705) and DIN 4754.
Subject to design code, a fired heater system may have the following typical components:
