About ClearSign Technologies
Industrial Instruments For Measurement, Display, and Control, SIC 3823
ClearSign Combustion Corporation designs and develops industrial technologies focused on decarbonization, operational efficiency, and emissions reduction for combustion systems.

The company provides process burners, boiler burners, and flaring systems, while also engineering the ClearSign Eye non-contact flame sensing device for industrial pilot ignition. Its solutions target customers across energy sectors, including upstream crude oil production, midstream natural gas processing, petroleum refining, and petrochemical facilities, as well as institutional, commercial, and industrial boiler operators.
