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. Sigma Thermal’s convection style direct fired heater utilizes a separate combustion chamber and flue gas recirculation to reduce combustion chamber temperatures to 1,400F, thereby minimizing the impact of radiant heat transfer to the process coil.
