Ultra Low NOx <5ppm

Cutting edge technology capable of meeting sub 5 ppm NOx guarantees in fielded applications.

No Flame Impingement

Due to the arrangement of the burner and its combustion surfaces, flame dimensions are significantly reduced, making the burner suitable for retrofits in existing heaters that do not meet current API guidelines.

Increase Heater Duty

Due to the burner arrangement, a conventional burner tile is not required, allowing the burner to increase fired capacity without the need to change existing cutouts in the furnace floor. This allows for quicker and less expensive retrofit / burner changeouts.

Low CO Emissions

Due to the burner technology’s reduced need for entraining flue gas within the furnace, CO emissions are greatly reduced over current generation burners in cold furnace environments.

Round or Flat Flame Configurations

The ClearSign Core™ burner technology arrangement is highly adaptable with the ability to shape the geometry of the flame and radiating surfaces to optimize heat flux for different furnace applications.

Natural Draft and Forced Draft Applications

The burner can be operated under natural draft or forced draft conditions.

Why ClearSign Core™

With environmental challenges pushing NOx emissions to lower levels, the intersection between conventional ultra-low NOx burners flame volumes and retrofitting into heaters designed for conventional flames, the only solution for NOx reduction was to add a post combustion SCR system to a heater.

FAQ

Q – What level of airside pressure drop can the burner handle? I have a forced draft application and the pressure drop is utilized to even the air distribution in air ducting to the burners.2019-10-23T16:35:30+00:00

The burners can be designed to operate with an airside pressure drop as high as 12 in. H2O.

Q – Where can I see ClearSign Core™ burners in operation?2019-11-24T02:20:40+00:00

Please contact us and we can arrange a demonstration in our test facility located in Seattle, Washington and also some field installations.

Q – What amount of hydrogen in my fuel can the burner be designed to handle?2019-10-23T16:34:20+00:00

Depending on the range of fuels required for operation, the hydrogen level in fuel can be handled from 0% up to 75% on a volume basis.

Q – What kind of turndown range can I expect to control my NOx and CO emissions?2019-11-24T02:24:54+00:00

A turndown range of 5:1 is possible for controlling pollutants.

Q – My heater has a floor fired heat intensity greater than 300,000 Btu/hr/ft2. Can ClearSign’s core burner technology still meet low NOx emissions?2019-11-18T20:53:14+00:00

Absolutely, unlike current ultra low NOx burners, ClearSign’s technology does not achieve low NOx emissions solely on flue gas entrainment within the furnace.  Due to its well mixed fuel and air stream, the burner generates extremely low NOx.  Even with disruptive furnace currents and reduced flue gas recirculation within the furnace, the burners will still produce industry leading NOx emissions.

Q – Does the burner require a warmup period for operation?2019-11-24T02:24:18+00:00

No.  Once the burner pilot is ignited, the main flame can be brought online and ramped up within your heater’s standard operating procedure.

Q – What kind of fuel pressure is required?2019-10-23T16:31:49+00:00

The burner can be designed to operate with 20 – 35 psig.  The design can work at lower pressures, but it may impact turndown.

Q – If my operators operate the burner with higher than desired levels of O2 will this affect my NOx emissions?2019-11-24T02:21:54+00:00

Yes, if the furnace is designed to operate at 3% O2 and is actually run at higher oxygen levels due to wind or other operating issues, the NOx from the burners will actually reduce.  This is on a raw NOx and a corrected NOx basis.

The initial cost, space constraints and overall project costs to install and maintain the SCR, makes this solution prohibitive in terms of a widespread solution.

ClearSign Core™ technology allows the owner / operator to do an in-kind replacement of existing burners and not only meet stricter NOx regulations but also potentially debottleneck a furnace if higher firing capacity is a limitation.

ClearSign Core™ process burners are ideal for existing heaters where NOx solutions with an SCR are too expensive and current generation ultra-low NOx burners cannot meet the NOx emissions or fit the flame volume into the existing furnace.

CEO Jim Deller met with a few customers to understand the financial impact of reducing NOx emissions.  “It became apparent that ClearSign Technologies could provide a solution to the immense barrier that upfront equipment cost can pose for refineries seeking to reduce their NOx emissions.  We’ve created a path forward, and it’s our goal to help in every way we can to create a future with lower emissions and ultimately a cleaner environment.” said Jim Deller, CEO of ClearSign Technologies Corporation.
