Complying with increasingly tough emissions requirements is a continued challenge for the boiler industry. Conventional ultra-low NOx burners have been pushed to their limits; they have become increasingly complex and costly and in some regions, still, fail to meet current NOx requirements. SCRs can meet these new emissions regulations, but they come with significant capital and operating cost and the need for additional training to handle required catalysts and reagents.

ClearSign Technologies offers a superior solution– the ClearSign CoreTM Fire Tube Boiler Burner. Simply put, this product delivers SCR-level performance in a compact burner that is both cost-effective and simple to operate and maintain. Thoroughly tested in a variety of boiler configurations, the ClearSign Core Fire Tube Boiler Burner can yield sub 2.5 ppm NOx without costly catalysts, hazardous chemicals, extra ducts or controls.
