Combustion Apparatus TRIZ Cases
- Gas Heater Flame Detection Using Temperature After Sensor Failure
Temperature sensing backs up failed UV or ionization flame detection in hydrogen gas heaters to prevent unburned fuel leakage.
- Optical Burner Flame Detection for Safe Hydrogen Ignition
UV flame sensing and pre-ignition spark detection help a burner controller prevent unignited hydrogen buildup and loud ignition bangs.
- Heater Flame Presence Control During Power Modulation
Activating the ignition device during heater modulation enables rapid reignition and avoids false shutdowns from delayed flame detection.
- Electric Field Flame Actuation for Thermoacoustic Instability Suppression
Replacing mechanical actuators with electric fields stabilizes lean combustion by suppressing thermoacoustic instabilities and reducing NOx emissions.
- Electric Field Flame Stabilization and Heat-Release Modulation
Applying an electric field to the combustion process stabilizes lean flames and suppresses thermoacoustic instabilities without complex mechanical actuation.
- Burner Control Device Ionization Current Correction
A burner control device interpolates ionization currents to adjust air volume flow without abrupt changes.
- Ionization Electrode Flame Monitoring via Dual Voltage Cycling
A voltage generator supplies an ionization electrode with alternating voltage levels to measure flame currents for heating device control.
- Flame Monitoring via Thermal Gas Sampling
Remote thermal gas sampling detects flame status by distinguishing exhaust from ambient air, preventing hydrogen accumulation hazards.
- Fire Tornado Inducer Using Angled Air Nozzles
Angled air nozzles deliver flow to create eddy currents around a flame element, enabling controlled fire tornado observation without natural safety risks.
