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.

CLEARSIGN DELIVERS 3 SUCCESSFUL

OTSG Installations To Central California Customer

A Case Study.

A California based customer approached ClearSign interested in applying the technology to meet the area’s strict emissions regulations. The initial field application scaled the bench scale burner with a firing rate of 250,000 Btu/hr to a 62.5 MMBtu/hr production unit with an emissions target of sub 6 ppm NOx (corrected to 3% O2, volume, dry).

FAQ

Q – How does the ClearSign Core™ technology compare with respect to legacy equipment?2019-11-18T20:20:46+00:00

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

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?2019-11-18T20:28:10+00:00

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 via the near black body ceramic tiles, thereby affording the user increased thermal efficiency.
