The SER combustion system of ESA-PYRONICS is a complete unit combining the burner, the radiant tube and the recuperator into a single compact device. As it passes through the SER’s recuperator section, incoming combustion air is preheated by the hot exhaust gases. Burner ignition is achieved by a direct spark ignition electrode (Wand) which may be easily installed from outside without disassembling the burner. A micrometer type valve, air and gas orifices allow for accurate combustion control.
