Burner to be Installed at Recycling Plant in California


TULSA, Okla., February 21, 2023 — 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, today announces another sale of their fire tube boiler burner technology into the California market to a national service provider of recycling services to the food production and restaurant industries.


“We are pleased to announce this second order of our ultra-low NOx boiler burners on the heels of our first sale just days ago,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. “We believe our industry and the market are taking notice of the solutions we provide.  Our marketing and promotional efforts with Rogue Combustion, a subsidiary of California Boiler, are gaining momentum and we are all encouraged by these initial orders and growing pipeline.”


“This burner is our first commercial boiler burner sale guaranteeing sub 2.5ppm NOx, specifically developed to enable clients like this to operate in compliance with California Central Valley region’s new regulations and without the need for ammonia and the hazards associated with such potent chemicals.  Our burner will be part of a recycling plant upgrade that will increase energy efficiency for one of this customer’s nationwide sites,” concluded Dr. Deller.


The boiler burner will be installed with a new boiler and was sold as a package with our partner California Boiler into the San Joaquin Valley Air Pollution Control District of California. The burner and boiler are scheduled to be installed in the third quarter of 2023.
