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 heater applications.
Direct fired heaters are used for specific applications.
We ve put together a video with some of our most common direct fired heater applications which you can see below.
A convection style heater offers the benefits of a direct fired heater while eliminating some of the drawbacks associated with radiant heat transfer.
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.
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.
