Convection Recuperators
In convection recuperators the gas to be heated usually flows through the tubes. Channel recuperators are installed in the exhaust gas duct and can be used at temperatures up to approx. 1,000°C. Recuperators with U-shaped tubes are designed for applications in which the thermal process causes extreme variations of the gas volume or the temperature.
Radiation recuperators are most suited for highest exhaust gas temperatures. Due to their particular geometry, it is recommended to install them in systems with exhaust gases containing a high dust load. While the exhaust gas flows through the free cross section of the recuperator with minimal pressure drop, the air to be heated is directed through a narrow gap, formed by two concentric steel cylinders.
Alternatives to this double shell design are the tube basket type that uses tubes, which are welded between two headers or combinations of both systems. |
Clyde Bergemann Senior Thermal, formerly known as Senior Thermal Engineering Australia Pty Limited have been designing and manufacturing a range of tubular recuperators since the early 1960's. The knowledge and experience of our highly qualified team of engineers and technicians, plus our proven equipment designs, backed by a continuing program of research and development through our principals ensures our clients of up to date service and technology solutions.
