ClearSign Combustion Corporation (NASDAQ: CLIR) designs and develops technologies that aim to solve the greatest challenge facing the energy industry today: capital intensive emissions control requirements which reduce process throughput, consume energy, complicate design and destroy profits. Our technologies offer simple retrofit strategies for superior emissions control and improved performance during combustion for a fraction of the cost of after-treatment methods which can only address part of the problem. Our methods can be deployed anywhere there is an open flame, regardless of the fuel type.

Nearly two-thirds of global energy consumption is accounted for by combustion of hydrocarbon and other fuels in boilers, furnaces, kilns and turbines. These systems are used to generate electrical power, to provide heat for all manner of industrial processes and for building heat. They produce more than 50 quadrillion British thermal units (Btus) of energy annually in the U.S. In order to maximize energy efficiency while keeping pace with regulatory guidelines for air pollution emissions, operators of these systems are continually installing, maintaining and upgrading a variety of costly process control, air pollution control and monitoring systems.

Our Electrodynamic Combustion Control technology introduces a computer-controlled electric field into the combustion zone to improve control of flame shape and heat transfer. This same technique can also be used to optimize the complex chemical reactions that occur during combustion in order to minimize harmful emissions while maximizing system efficiency.

While our technology can be applied at any scale, the potential cost savings and economic benefits to operators of large-scale combustion systems are considerable. ECC is, to our knowledge, the only combustion technology that exists today that has the ability to simultaneously improve emissions control performance and meet regulatory standards, while yielding a significant increase in energy efficiency. ECC can be adapted to various fuel types and multiple system sizes and configurations, and can be deployed on both a retrofit and new-build basis.
