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 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
ClearSign Core process burners are well suited to both heater configurations. Also, the ClearSign Core process burner can meet challenging applications whether it is short flame lengths or increasing capacity without opening the heater floor or refractory.
Please contact us and we can arrange a demonstration either in a test facility or at one of our customer locations.
In most cases no modifications will be needed. ClearSign Core burners will fit directly into existing heater cutouts and connect directly to typical fuel gas piping.
The burners are fitted with an industry standard pilot, typically with electric ignition, and light up just like a standard industry burner.
Yes, full technical support is provided through the proposal process. We cover burner supply from start to finish, including testing and CFD modelling as required.
Yes, our technology is developed to handle up to 100% hydrogen. We also control NOx emissions to avoid the NOx increase usually associated with adding hydrogen to the fuel gas blend.
Absolutely. Unlike current ultra-low NOx burners, ClearSign’s technology does not achieve low NOx emissions solely on flue gas entrainment. Our burner generates extremely now NOx due to its well mixed fuel and air stream.
