The term “convection” refers to the transport of heat through macroscopic material flows in liquids or gases. Such a heat exchange occurs in the Peiler Convection Recuperator: cooling air streams are passed over the exhaust gas stream through a large number of pipes, ensuring rapid removal of heat. Peiler Convection Recuperators can be used in all types of furnaces, provided that there are no aggressive substances in the exhaust emissions. The Convection Recuperator itself has a relatively favorable level of thermal efficiency if the exhaust gas temperatures are in a low range. The Convection Recuperator can be ideally adapted to the operating requirements by dividing the pipe systems into materials of the same or different quality. The easy replacement of pipe groups or bundles makes repair of this type of recuperator simple. The Convection Recuperator operates economically at exhaust gas temperatures up to 1,000 °C, where air preheating temperatures up to 650 °C and pipe wall temperatures up to 850 °C can be achieved. Peiler Convection Recuperator used

• Rolling Mill Furnaces
• Holding Furnaces
• Batch Ovens
• Aluminum Melting Furnaces
• Post-Combustion Systems

The Peiler Radiation Recuperator removes heat in a single double-walled tube. The robust construction and smooth inner wall of the pipe make it suitable for use with flue gases with temperatures over 1,000 °C and especially flue gases containing aggressive components. Its durability under these conditions is much superior to other types of recuperators. Peiler Radiation Recuperator is used in the following cases:

• Rolling Mill Furnaces
• Holding Furnaces
• Batch Ovens
• Aluminum Melting Furnaces
• Ceramic Kilns
