Direct fired heaters are used for specific 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.
Direct fired heaters can either be used in radiant or convection heat exchanges and adopt different configurations according to their applications.
A convection style heater offers the benefits of a direct fired heater while eliminating some of the drawbacks associated with radiant heat transfer.
Fired heaters designed for refinery applications are generally designed for allowable average radiant heat flux q r which is one of the most closely watched design factors of fired heaters for given process application for determination of average radiant heat flux it is necessary as a first step to determine the radiant heat duty q r all of existing well established 1dquasi theoretical.
Direct fired heaters are great for use in a variety of environments especially in warehouses construction sites and outdoor spaces.
These units operate much like a gas stove or grill and push air through an.
