It is known that the temperature of combustion flames should be less than 3,272 F to prevent NOx generation. Generally, combustion flames will have some high temperature areas generating NOx. Miura engineers calculated the temperature distribution in the combustion and the heat exchanging areas. From theoretical analysis and rigorous testing, the designed temperature distribution is homogeneously less than 3,272 F. The burner surface is made as large as possible and the furnace volume as small as possible to optimize the combustion process. As a result, with no efficiency loss at 3% O2 and 85% efficiency, the LX has NOx emissions of less than 20 ppm (lower NOx available for California).       For availability of models with low NOx ratings for your area, including California's SCAQMD, contact your Miura Representative   © 2006 Miura Boiler Co., Ltd.
