Replacement will pay for itself
Burner chambers are the heart of a Contiweb dryer, combusting the ink solvents at very high temperatures (800 C). This results in clean air emissions meeting the legal requirements to exhaust. By using efficient heat exchangers and low air flows, Contiweb manages to keep gas consumption low.
Burner chambers operate on high air speed and high temperatures. Heating and cooling lead to expansion of the steel of the burner chambers and give plastic deformation over the years. In average, the lifetime is between 12 and 15 years, which means the burner chambers should be regarded as wear parts that eventually will need to be replaced.
Towards the end of life the number of repairs increase and repair costs rise, CO in the exhaust can increase above legally permitted levels, or the required air flow can no longer be achieved. Most costly of all, unplanned burner downtimes need to be prevented from halting production. Periodical inspections and emission measurements indicate the condition of the burner chambers.
Energy efficient options
Over time Contiweb has improved the design of the burner chambers to be more robust. Contiweb will supply a fully functional replacement burner chamber that complies with the latest legislation. Dryers equipped with Contiweb’s Type C Chamber can be upgraded to Chamber C+ (1460 mm web width) or C++ (1680 mm or wider).
The C+ and C++ combustion chambers have a high-efficiency heat exchanger to save gas by recovering waste heat. In addition, the C++ chamber increases the machine lifetime. New burners and new hot air valves can be installed at the same time. So too can our Gas Reduction Enhancement (GRE) which further reduces gas consumption and reduces carbon footprint.
