OUR CHANNEL TO MARKET

A team of experienced technicians, control experts, and leading-edge combustion theory scientists chose to “Go Rogue” by starting from basic principles rather than modifying existing low NOx burner design which had already been pushed beyond their limits. The partnership became Rogue Combustion, LLC and the result is the Rogue Burner and Control Series with ClearSign Core™ technology.

Firetube Boiler

A firetube boiler is a type of boiler in which hot gases pass from a combustion zone through one or many tubes running through a sealed container of water. The heat from the gases is transferred through the walls of the tubes by thermal conduction, heating the water and creating steam. Such boilers can be further classified as single pass, two, three or even four pass to denote the number of loops or passes the flue gases make prior to exiting via the stack.

Watertube Boiler

A watertube boiler is a type of boiler in which water circulates in tubes heated externally by the combustion process. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. The heated water then rises into the steam drum where saturated steam is drawn off the top of the drum. In some services, the steam will reenter the furnace through a superheater to gain additional enthalpy/energy.

FAQ

Q – How does the ClearSign Core™ technology compare with respect to legacy equipment?2021-11-15T16:22:46+00:00

The technology provides unprecedented emissions levels (~2.5ppm NOx at 3% O2) compared to traditional equipment without the use of reagents, high excess air conditions or degradations in thermal efficiency

Q – Do I need to operate the boiler any differently with ClearSign Core™ installed?2019-11-18T20:36:02+00:00

No, the Clearsign technology can be operated in exactly the same manner as a legacy burner with regard to start up, ramp rate and shut down protocols.

Q – What fuels do boilers use?2019-11-18T20:23:37+00:00

Natural gas, coals, liquid distillates and biofuels

Q – What modifications do I need to make on my equipment?2019-11-24T02:30:34+00:00

Basically none. The Clearsign Core™ technology is a retrofittable technology that is easily inserted through the same boiler burner openings as the OEM burner.

Q – How can I buy the ClearSign Core™ Technology?2019-11-18T20:26:26+00:00

Clearsign sells its technology through its channel partners or equivalently through Clearsign itself for retrofit applications.

Q – How does ClearSign Core™ Technology Work?2021-11-10T15:25:39+00:00

A distal metallic flameholder and continuous pilot are located downstream of the conventional burner location. Fuel pokers inject fuel downstream and entrain FGR. The cold charge thoroughly mixes as it approaches the flame holder. Thorough mixing of all gas streams, a continuous pilot, and robust flame anchoring ensure excellent combustion stability and superior emissions performance over the operating envelope.
