Please contact sales@ClearSign.com. We would love to learn more about your specific use case and determine if the sensor is the solution for you.
Yes, the sensor can be used to detect a plugged nozzle. This is indicated by a drop in the normal operating signal. It is also possible to arrange multiple sensors to detect each nozzle independently, providing a higher fidelity to the burner operation.
The flame signal provided by the sensor is related to the operating conditions of the flame. This includes the equivalence ratio, fuel type, and firing rate. If any of these parameters change, the signal will change. An operator can use the signal as a lifeline signal to see if there are any major deviations in
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, therefore the sensor typically operates at a more useful millisecond timescale.
The sensor can provide standard outputs including an ON/OFF led indicator, dry contact relay, 0-5V, and 4-20ma.
Yes, a pilot flame typically provides a smaller flame intensity signal than the main flame, allowing the sensor to differentiate between the pilot and main flame.
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.
No, unlike a flame rod the ClearSign Flame Sensor does not have to contact the flame. The electrodes are typically positioned upstream near the perimeter of the flame zone.
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.
