ClearSign Completes Testing of 100% Hydrogen Capable Burner
ClearSign Technologies announces that, in conjunction with the U.S. Department of Energy's National Energy Technology Laboratory, under its Small Business Innovation Research program, it has completed the testing of its ClearSign Core Flexible Fuel, 100% Hydrogen Capable process burner branded as ClearSign Core 2. "We are very pleased to publicly report the success of this flexible fuel burner development project," said Jim Deller, CEO. "We are thankful for the SBIR program funding that allowed us to develop and demonstrate a technology designed to meet the real-world needs of U.S. refineries and chemical processing facilities. This technology enables compliant and cost-effective use of fuels ranging from 100% hydrogen, the full gamut of petrochemical and refinery hydrocarbon fuel gas blends, and natural gas in industrial heating operations. We believe that these ultra-low NOx results and ease of use are unmatched by any other burner that we know of in the market." ClearSign's "Flexible Fuel Ultra-Low NOx Process Burner" project, which is nearing its scheduled completion and marking a significant 2.5-year effort, resolves this issue by facilitating fuel flexibility without compromising emissions compliance with the simple replacement of burner technology. This innovative technology allows industrial facilities to enhance operational flexibility, reduce costs associated with fuel procurement and regulatory emissions compliance, and reduce disruptions to operations - all of which may provide Americans with more affordable energy. The ClearSign Core burner, scaled to 8 million British thermal units per hour, has demonstrated consistent performance across a range of fuel compositions, including 100% hydrogen, natural gas and various intermediate blends. This technology has also achieved NOx emissions that are consistently below 5 parts per million across this entire range of fuel gas blends. This is accomplished through integrated features such as internally induced flue gas recirculation, fuel-lean premixing and a patented distal flameholder, all contained within a compact burner head designed for easy retrofitting into existing heater infrastructure.
