Direct fired heaters can either be used in radiant or convection heat exchanges and adopt different configurations according to their applications.
Direct fired heater applications.
A direct fired heater or an industrial furnace uses the hot gases of combustion to transfer the heat to the liquids flowing in the heat exchange coils.
These units operate much like a gas stove or grill and push air through an.
A convection style heater offers the benefits of a direct fired heater while eliminating some of the drawbacks associated with radiant heat transfer.
Radiant heat transfer can be undesirable in certain temperature sensitive applications as radiant heat transfer tends to be more intense and unevenly distributed around the coil surface.
Direct fired heaters are used for specific applications.
Direct fired heaters are great for use in a variety of environments especially in warehouses construction sites and outdoor spaces.
