Boiler Breakthrough: Near-Zero NOx Emissions
"Miura has developed a technology which dramatically reduces the nitrogen oxide (NOx) concentration in the exhaust gas of gas-fired steam boilers to below 1 ppm at O2 = 0 percent equivalent compared to over 30ppm of conventional U.S. boilers," explained Yuji Takahashi, company president. "This important advance represents a significant step forward in reducing pollution."
Features of the new technology include NOx concentration of 1 ppm and below (at continuous operation); a new combustion control method that makes it possible to reduce heat loss by 20 percent compared to current products; and an environmentally friendly catalyzer that does not use chemicals such as urea and ammonia. It's projected that the technology will be available in North America by 2010.
