The technology provides unprecedented emissions levels (~5ppm NOx at 3% O2) compared to traditional equipment without the use of reagents, high excess air conditions or degradations in thermal efficiency
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.
Natural gas, coals, liquid distillates and biofuels
Basically none. The Clearsign Core™ technology is a retrofittable technology that is easily inserted through the same boiler burner openings as the OEM burner.
Clearsign sells its technology through its channel partners or equivalently through Clearsign itself for retrofit applications.
A distal porous ceramic flameholder is located downstream of the conventional flame holder/burner location. Fuel pokers inject fuel towards the ceramic body and entrain FGR as the cold PREMIX thoroughly mixes as it approaches the flame holder. A small burner near the module ensures flame stability and continuous ignition. High radiant heat transfer is ensured
