Boiler Breakthrough: Near-Zero NOx Emissions

Steam, generated from gas and oil-fired burners, remains a primary source of energy for a wide range of industrial applications including food processing and medical product manufacturing. Emissions from these boilers include nitrogen oxide (NOx) and carbon dioxide (CO₂). Reducing these emissions has been the goal of Miura Boiler, a leader in process steam boiler technology. The company recently announced a breakthrough in its effort to achieve 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.
