Fired Heater

Product Introduction.

A fired heater is aspecialised process heater typically used in industries including:

●   Petroleum Refining.

●   Petrochemical Production.

●   Coal Chemical Industries.

●   Tar Processing.

●   Crude Oil Transportation.

The exhaust temperature of a fired heater can be as low as 100oC.This low temperature can achieve partial condensation of the water vapourpresent in the flue gas. This condensate will be acidic and must be treatedfurther.

As well asrecovering the low temperature sensible heat in the flue gas, it is alsopossible to recover the latent heat of vaporization of the water vapour. Thissignificantly improves the thermal efficiency of the heater with its resultingsaving in energy.

Product Features.

A fired heatertypically has the following features and requirements：

●   The heated product flows through the heater tubes soit is therefore limited to heating liquids or gases.

●   The heated product is not water and steam but oils andgases that are flammable, explosive, easily cracked, prone to coking and oftenhighly corrosive.         

●   The heating process is the direct fire type, requiringthe furnace tubing to be able to withstand high temperatures, high pressuresand a corrosive medium.

●   Fuel can only be a combustible liquid or gaseous fuel.

●   These heaters typically operate on long, continuouscycles with uninterrupted operation.

Thesefeatures require a specialised design, material selection and manufacturingprocesses. BSS have extensive experience in all of these requirements for firedheaters in many applications.
