SEATTLE, April 18, 2017 /PRNewswire/ -- ClearSign Combustion Corporation (NASDAQ: CLIR), an emerging provider of industrial combustion technologies that help to reduce emissions and improve efficiency, today announced that it has secured a follow-on commercial order from a California-based refinery following Duplex™ technology's successful pilot with the company late last year.

The installation marks the first installation of the Duplex technology into a new heater rather than a retrofit into a heater with an existing burner.

In the pilot project, ClearSign had previously retrofitted the company's vertical cylindrical refinery heater with its unique, patented, Duplex technology to ensure compliance with California's strict air emissions requirements. After the retrofit, independent testing conducted by a third party on behalf of the refiner confirmed NOx (oxides of nitrogen) single digit emissions, performance that would qualify as Best Available Control Technology (BACT) in any jurisdiction within the U.S.  

"We're pleased with the company's continued vote of confidence as they've been an excellent partner in applying our technology to their refinery," said ClearSign Chairman and CEO Steve Pirnat. "We look forward to working with them to achieve their future emission goals as we've done so in the past."
