From the Horizontally Fired Process Burner Product Line

Sold By Heater Manufacturer Devco Process Heaters

TULSA, Okla.June 26, 2024 /PRNewswire/ — ClearSign Technologies Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), an emerging leader in industrial combustion and sensing technologies that improve energy, operational efficiency and safety while dramatically reducing emissions, announces a burner sale from the horizontally fired process burner product line.

“This sale is meaningful for multiple reasons,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. “First, this is the largest boiler burner we have sold to date, at close to 90 million BTU/hr, or almost two times the size of our previous largest single burner. With this we will have demonstrated products designed for our small, medium and large size ranges in the field. Secondly, this burner was sold in collaboration with another heater manufacturer, Devco Process Heaters, into the midstream market, which will introduce our solutions to new customers and expand our sales channels.”

The burner was sold by Devco Process Heaters of Tulsa, OK and will be going into a new heater in a central Texas gas processing facility. The Company expects to deliver the burner in the third quarter.
