OIT Times: New Burner Cuts NOx While Improving Boiler Efficiency
June 23, 2001
Demonstrating 9 ppm NOx performance, the Combustion program Forced Internal Recirculation (FIR) burner is a revolutionary advance in burner technology. ypically, low emission burners sacrifice efficiency, but this burner provides increased heat transfer efficiency in boiler applications,said program manager Bob Gemmer (202-586-5885). The burner is applicable to a wide range of boilers, and near-term commercialization is expected.
The Industrial Materials of the Future program has helped solve a major problem long plaguing the paper industry, according to program manager Charlie Sorrell (202-586-1514). omposite tubes have had a high failure rate in Kraft recovery boilers, sometimes leading to explosions,he said. OIT sponsored a project to determine the cause and develop a set of new operating procedures and materials suggestions. everal companies have already adopted these insights and solved the problem,he said.
The Sensors & Controls program in partnership with the Steel Team is demonstrating laser ultrasonics technology at a Timken steel plant. Laser pulses instantly determine steel tube wall thickness and other parameters, allowing real-time adjustments and saving a large chunk of the $234 million in waste attributed to inadequate process controls. A separate Timken effort is using laser ultrasonics to measure grain size. hese are pioneering applications demonstrating the vast potential of laser ultrasonics in an industrial setting,said program manager Gideon Varga (202-586-0082).
