Burner to be Installed in CA Market

TULSA, Okla., February 14, 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 the first sale of their fire tube boiler burner technology into the California market.


“We are delighted to announce the first sale of our ultra-low NOx boiler burners,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. “We have been steadily promoting our ultra low emissions, clean air capabilities with Rogue Combustion, a subsidiary of California Boiler who provides the direct customer facing installation and services of this product line in the U.S. We believe this business segment is starting to gain traction and will be meaningful for the company.”


“While this first domestic commercial fire tube boiler order is significant in and of itself, it is also very encouraging because the customer came to us for our solution after competing products failed to meet the new district sub 5ppm NOx emissions requirements.  Additionally, we are excited to translate this sale into a whole new business vertical of medical and business waste services.  This last point helps demonstrate that these boiler burners have a very wide variety of uses in industries in the U.S. and around the world,” concluded Dr. Deller.


The boiler burner order was sold in conjunction with our partner California Boiler into the San Joaquin Valley Air Pollution Control District of California. The burner is scheduled to be installed in the second quarter of 2023.
