Oil refining and petrochemical manufacture involves extensive heating of hydrocarbon and other fluids. Depending on the temperature required, this heating is achieved either by steam or direct heating. In the latter case, the fluid under pressure is contained in tubes which are heated from the outside by direct exposure to flames. These heaters commonly take two forms, cylindrical heaters with one central burner, or a ring of burners in the base and the long rectangular type with many burners in a row along the floor, the latter are generally known as cabin heaters. This paper shows the design of one such furnace.
