Applications

INDIRECT HEATING

• Inert gas roller hearth furnaces
• Inert gas chamber furnaces
• Continuous strip lines
• Use in single-ended radiant tubes, P- and double-P radiant tubes

DIRECT HEATING

• Chamber furnaces for heat treatment
• Bogie hearth furnaces for heating and forging
• Rotary hearth furnaces
• Roller hearth furnaces with open flame

RECUFIRE® recuperative burners are conceived for an application in indirect heating systems such as single-ended radiant tubes, P- and double-P radiant tubes. Heat is transferred to the furnace chamber by temperature radiation of the radiant tube. In combination with the ceramic segment flame tube FIREFLEX®. Maximum temperature uniformity is achieved with the different radiant tube diameters and gas types.

The patented segment flame tube FIREFLEX® allows a considerable deflection range of metallic flame tubes without suffering any damage itself (see picture). We would advise our ceramic single-ended radiant tubes which are laid out for coping with the most exacting thermal stress.

Open Heating Recufire

Due to the IBS exhaust gas ejector the RECUFIRE® recuperative burner technology is also available for industrial' furnaces with open heating. The exhaust gas ejector functions like a jet-pump and draws off the exhaust gases 100 % from the furnace chamber by means of the burner recuperator. The adjustable suction effect of the exhaust gas ejector makes it possible to directly influence the furnace chamber pressure. Thanks to the ceramic recuperator made of SiSiC, the recuperative burner RECUFIRE® is suitable also for exposure to the most exacting thermal stress, for example in forging furnaces.

Energy Saving

The following graphs display the thermal efficiency, the combustion air preheating and the corresponding energy saving of the recuperative burners RECUFIRE®. The stated "exhaust gas temperature before Recu" indicates the furnace chamber temperature in open heated furnace systems. In furnaces heated by radiant tubes the "exhaust gas temperature before Recu" is about 130 -150 K above the furnace chamber temperature. This fact must be taken into account when choosing the burner (ceramic material for higher temperatures). The figures in the graph only serve as guides; please give us the technical data of your application as they form the basis of our design.

Regenerative Burner Systems

REGFIRE®

REGFIRE® is a uniquely compact regenerative burner, which was created by IBS (Industrial Burner Systems) in 2011 in order to obtain the highest air preheatings. This regenerator is an integral part of the burner housing which leads to the small overall dimensions of the burner.

REGFIRE® is available in three sizes for 500 kW, 750 kW and 1,500 kW capacity. For lowest NOx-emissions the burner can be switched to flameless mode when the furnace temperature exceeds 850°C.

Characteristics:

• Burner for operation in pairs on forging and reheating furnaces
• Highest preheating of the combustion air
• Firing efficiency in a forging furnace e.g. 85%
• Different sizes with capacities ranging from 400 kW up to 1,500 kW
• Operating temperature up to 1,350°C
• Uniquely compact design due to the integration of the honeycomb heat exchanger
• Pneumatic driven switch valve for FLUE GAS and AIR as part of the burner
• Low effort for maintenance and cleansing
