ClearSign Texas Refinery Project Successfully Concludes Operational Testing

ClearSign Combustion Corporation announced that it had successfully completed the first installation of its revolutionary product, The Duplex Plug and Play, for industrial process heaters at a refinery in Texas. Unlike traditional burners, Plug and Play uses patented Duplex™ technology to enhance the combustion process ensuring best available, ultra-low emissions while enhancing operational efficiency by increasing the mean time between heater maintenance cycles that require furnace shutdowns.

The Plug and Play product improves heat transfer while eliminating flame impingement on process tubes. Flame impingement avoidance greatly reduces maintenance related shut downs and is a feature unique to ClearSign.

The six burner test heater was chosen by the Texas refinery to demonstrate the Plug & Play’s ability to control flame impingement and improve emission performance. Starting with one burner, and incrementally adding subsequent burners as the customer’s maintenance schedule allows, the first installation of Plug & Play has achieved the project goals. ClearSign is coordinating the subsequent roll out of the follow-on order to conform with the refinery’s maintenance schedule and expects to finish the project by years’ end.

“Needless to say, this is a very significant milestone in our evolution of Duplex Technology into a fully integrated product for industrial process heaters and boilers,” said Steve Pirnat, Chairman and CEO of ClearSign. “We view the global market potential of Duplex Plug and Play as significant due to the fact that it solves unmet needs on both the environmental and operational level in a cost-effective manner that no other burner or environmental control can offer. The interest from domestic and foreign companies continues to grow, especially in China and we expect additional orders in the short to mid-term.”
