Furnaces and Fired Equipment

Abstract

Furnaces or fired heaters are used to raise the temperature of process fluids. There may be more to this than simple heating, as sometimes (as with, e.g., cracking or reforming furnaces) this causes chemical and physical changes to take place in the process streams passing through the heater. Typically the term “fired heater” refers to equipment that simply heats a fluid, while a “furnace” is typically more complex, and usually include a process reaction and/or multiple services. The first consideration in the layout of fired equipment is safety.
