Description

Global warming is one of the biggest threats to our environment. Therefore, energy efficiency measures as well as emission reduction have become a top priority for large energy consuming industrial sectors like the field of industrial furnaces. The change in the European energy police has important significance for the industry in terms of reducing CO2 emissions. Based on these challenges, this paper highlights potential savings, which can be practically implemented today, as well as forward-looking solutions.
In order to detect saving potential a mass- and energy balance was set up for a gas-fired pusher type furnace. Focusing on the exhaust gas losses the burner technology itself, but also alternative energy sources like H2 – even the changeover to electrical heating systems – were discussed in detail. In parallel NOx emissions have to be taken in account. Furthermore, secondary energy saving measures like heat extraction were taken into consideration and incorporated into the evaluation. With respect to maintenance issues the aspect of improving thermal insulation of heat treatment furnaces was analyzed under economic aspects as well.
It has to be pointed out, that modern process control systems already offer numerous options to get an overview of the energy consumption and provide (partly) an energy-saving mode like standby mode and / or opportunities to optimize process parameter in terms of energy saving like adjustment of process gas flow rate for individual parts.
Anyhow, new technological developments are already in the pipeline and changes in the legal resp. political framework will open up many possibilities with a different perspective on ROI.
