I am with WS Wärmeprozesstechnik GmbH, a globally leading manufacturer of energy saving gas burner technology. Recognizing the deficiencies of conventional gas burners, WS developed the REKUMAT® high-velocity self-recuperative burner series. REKUMAT® burners use hot exhaust gases to preheat combustion air in counter-flow and can thereby achieve efficiencies up to 75 % or even up to 85 % with the new gap-flow heat exchanger of the REKUMAT® S. The REGEMAT® self-regenerative burners integrate ceramic honeycomb regenerators and switching valves into one compact unit. An efficiency of up to 88% LHV is possible due to the superior heat exchange between exhaust and combustion air. Both burner types are capable of using the FLOX® technology, enabling to achieve low NOx emissions even at high air preheat temperatures. With around 100,000 industrial burners installed worldwide since 1982, WS has proven that energy saving combustion systems have become increasingly important. The potential for emission and fuel savings remains huge and the payback times are short even in case of low energy prices.
