- [Q - My heater has a floor fired heat intensity greater than 300,000 Btu/hr/ft2. Can ClearSign’s burner technology still meet low NOx emissions?](https://clearsign.com/faq-items/q-what-kind-of-fuel-pressure-is-required/) - 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.
- [Q - Can ClearSign Core handle high hydrogen fuel gas?](https://clearsign.com/faq-items/q-does-the-burner-require-a-warmup-period-for-operation/) - 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.
- [Q - Does ClearSign provide full services for a burner order?](https://clearsign.com/faq-items/q-my-heater-has-a-floor-fired-heat-intensity-greater-than-300000-btu-hr-ft2-can-clearsigns-core-burner-technology-still-meet-low-nox-emissions/) - 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.
- [Q - How do you light and start up the burners?](https://clearsign.com/faq-items/q-what-kind-of-turndown-range-can-i-control-my-nox-and-co-emissions/) - The burners are fitted with an industry standard pilot, typically with electric ignition, and light up just like a standard industry burner.
- [Q - What modifications are typical to retrofit a heater with ClearSign Core burners](https://clearsign.com/faq-items/q-what-amount-of-hydrogen-in-my-fuel-can-the-burner-be-designed-to-handle/) - 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.
- [Q - Where can I see ClearSign Core™ burners in operation?](https://clearsign.com/faq-items/q-where-can-i-see-clearsign-core-burners-in-operation/) - Please contact us and we can arrange a demonstration either in a test facility or at one of our customer locations.
- [Q - Can I use ClearSign Core process burners in cabin and vertical cylindrical heaters?](https://clearsign.com/faq-items/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/) - 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.
- [Q - Does the ClearSign Core™ flare technology work in natural draft and forced draft applications?](https://clearsign.com/faq-items/q-does-the-clearsign-core-flare-technology-work-in-natural-draft-and-forced-draft-applications/) - Yes! The technology is very robust and has been developed to operate in a variety of applications that are designed to meet a wide range of customer needs.

- [White Papers - Flame Sensing](https://clearsign.com/faq-items/flame-sensing-white-papers/) - CLEARSIGN EYE™: PILOT SENSOR AFRC 2021 Industrial Combustion Symposium
- [Q - How does the ClearSign Core™ technology compare with respect to legacy equipment?](https://clearsign.com/faq-items/q-how-does-the-clearsign-core-technology-compare-w-r-t-legacy-equipment/) - 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 - How does ClearSign Core™ Technology Work?](https://clearsign.com/faq-items/q-how-does-clearsign-core-technology-work/) - 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
- [Videos - Flame Sensing](https://clearsign.com/faq-items/flame-sensing-videos/)
- [Q - What is the output of the sensor?](https://clearsign.com/faq-items/q-do-the-electrodes-need-to-touch-the-flame/) - The sensor control module connects to the customer DIN rail enclosure and provides a dry contact relay output along with the 4-20ma output. The relay output triggers after the set delay time when a "flame off" is detected.
- [Q - Is there a specific brand and/or type of Burner Pilot that is needed for this sensor to be applicable?](https://clearsign.com/faq-items/q-does-the-sensor-pickup-nearby-flames-such-as-in-a-multiburner-furnace/) - This Sensor was developed to be adaptable to specific customer configurations. The sensor is compatible with any industry standard process burner pilot regardless of OEM.
- [Q - How fast is the response time?](https://clearsign.com/faq-items/q-what-is-the-output-of-the-sensor/) - Very fast! The sensor is capable of measuring at a rate of about 10 microseconds. However, this is much faster than the dynamics of a flame. The sensor typically operates at a more useful millisecond timescale.
- [Q - Is the bracket or sensor assembly susceptible to grounding or shorting with wear?](https://clearsign.com/faq-items/q-how-fast-is-the-response-time/) - No. Unlike traditional flame rod and bracket assembly construction, which can wear and crack over time leading to signal issues or shorts, the majority of our components are stainless-steel, including the pilot bracket. This was done to make our ClearSign Eye Pilot Sensor more robust and reliable.
- [Q - Does the sensor pickup nearby flames, such as in a multi-burner furnace application?](https://clearsign.com/faq-items/q-how-can-the-sensor-be-used-as-a-health-monitor/) - No, the sensor only detects a flame locally and will not produce a signal from nearby flames; this includes adjacent burners as well as opposed burners.
- [Q - Do the electrodes need to touch the flame?](https://clearsign.com/faq-items/q-can-the-sensor-detect-a-plugged-nozzle/) - No. Unlike a flame rod, the ClearSign Eye™ Pilot Sensor does not have to contact the flame. The electrodes are typically positioned upstream near the perimeter of the flame zone.
- [Q - How do I see a demonstration of the ClearSign Eye?](https://clearsign.com/faq-items/q-where-can-i-buy-the-sensor/) - Please contact sales@ClearSign.com to schedule a virtual or in person live demonstration of the sensor.
- [Videos - Process Burner](https://clearsign.com/faq-items/process-burner-videos/)
- [Q - What modifications do I need to make on my equipment?](https://clearsign.com/faq-items/q-what-modifications-do-i-need-to-do-on-my-equipment/) - 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 does the technology work?](https://clearsign.com/faq-items/q-how-does-the-technology-work/) - The ClearSign Core technology principles are consistent across the different product offerings. A continuous pilot provides an ignition source to a well-mixed fuel and air stream that stabilizes on a bluff body downstream from the injection plane. The bluff body acts to stabilize the combustion process and help radiate the energy into the combustion environment
- [Q - How does the ClearSign Core™ technology operate?](https://clearsign.com/faq-items/q-how-does-the-clearsign-core-technology-operate/) - The ClearSign Core™ technology is simple to operate, each module has a main pilot and a waste gas fuel connection. Similar to other technologies, the pilot is lit first and confirmed. After confirmation, the waste gas can be introduced. Simple as that!
- [Q - Do I need to operate the boiler any differently with ClearSign Core™ installed?](https://clearsign.com/faq-items/q-do-i-need-to-operate-the-boiler-any-differently-with-clearsign-core-installed/) - 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.
