ClearSign Technologies Corporation (ClearSign) announced that it has received a purchase order from a Fortune 500 national refiner in connection with the first phase of the project to retrofit two process heaters with eight ClearSign Core burners each to be installed in their Midwest refinery.

The project consists of three phases.  The first is the receipt of the purchase order, which includes the fabrication and demonstration of a single burner.  The second phase is planned to be an order for the remaining seven burners to complete the first heater.  The anticipated third and final stage will be an eight-burner order for the second heater.

"We are proud to announce the start of this multi heater project comprised of a total of sixteen ClearSign Core burners," said Jim Deller, Ph. D, CEO of ClearSign.

"While this our largest process burner project to date, and also our first order from this major USA refiner, what is also encouraging is that this customer was driven to our solution to increase the process throughput of these heaters while also being able to benefit from our best-in-class NOx emissions reduction.  We are pleased to see our technology become more recognized and known in the prominent companies of the industry, and continue to look forward to its ongoing adoption, and the benefits we can provide for refining productivity and reduced air borne emissions."
