PYRONICS - SINGLE-ENDED RECUPERATIVE RADIANT TUBE COMBUSTION SYSTEM(SER)OR (UHF)
Single-ended Recuperative Radiant Tube Combustion System Radiant tube burners are recuperative style and available as single end (SER) or direct fired (UHF). In a furnace operating with a conventional radiant tube combustion system, 65 to 70% of the heat created by combustion is wasted in the ue gas. Single-ended recuperative radiant tube combustion system (SER) reduces that wasted heat dramatically. Because it uses up to 70% of the available exhaust gas heat to preheat incoming combustion air the furnace’s fuel consumption is reduced signicantly (Fig. 1). The result is average fuel savings of up to 50%. The patented SER is a complete system, combining burner, radiant tube and recuperator in a single, compact unit. It comes with all the accessories needed, from adjustable gas cocks to buttery valves to ignition system (Fig. 1). Fig. 1. As the incoming combustion air passes through the SER’s recuperator section, it is preheated by hot exhaust gases. The medium velocity, sealed nozzle mix burner utilizes both gas and preheated air and fires down a center flame tube to provide uniform progressive combustion. Because existing hardware and applications vary from facility to facility, every SER is custom engineered to maximize combustion efficiency. SER users typically experience fuel savings of 40 to 50%. Fig. 2. To determine the fuel savings expected, draw a straight line from flue gas temperature to post-conversion preheat temperature. For example, air preheated to 1200 degrees F from 1900 degrees F flue gas will result in fuel savings of about 37-1/2%. Every SER component is designed to give many years of reliable service. Materials are carefully evaluated to assure component life consistent with the application – generally speaking, FeNiCr or FeCrNi in either a cast or wrought form are used. These materials are fabricated or formed into components engineered for extended reliability. For example, the SER’s medium velocity burner provides delayed mixing and uniform progressive combustion, for even tube heating and temperature uniformity. Its innovative spark system delivers consistently troublefree ignition. Features like these result in reliable performance, year after year. The proof is in the field: thousands of SER’s are already providing dependable service in captive and commercial heat treat shops around the world. Because SER’s are easy to install and service, they reduce conversion downtime to a minimum. Installation is simply a matter of removing existing tubes and burners and re-piping the main gas and air supplies to the SER. Even for untrained personnel, it takes as little as four man-hours per tube. Servicing an SER is simple. The precisely sized and integrated components provide for easy adjustment of gas/air ratios. All of which means furnace efficiency can be maximized with virtually no sacrifice in productivity. Max. air pressure required 1.75” W. C. Max. gas pressure required 1” W.
