Combustion Regulation TRIZ Cases
- Gas Grill Bus Bar Design for Parallel Flame Sense Connection
See how a bus bar replaces daisy-chained burner wiring with parallel connections, simplifying w
- Flame Temperature Sensor Drift Compensation for Hydrogen Heaters
Compensates flame temperature sensor drift by scaling off-state resistance, enabling stable combustion air ratio control in hydrogen heaters.
- Flame Detection Signal Modulation for Intrinsically Safe Self-Testing
A modulated carrier and bandpass filter let a photodiode flame detector self-test its evaluation circuit and reject false positives.
- Furnace Stage Control Based on Heating Cycle Duration
By adjusting the furnace’s initial stage from prior cycle duration, the control approach cuts energy waste and improves heating response.
- Heating Burner Ignition Detection Using Air-Fuel Flow Recovery
Flow-rate analysis during startup detects irregular burner ignition from target-flow deviation and recovery time, helping prevent damage and noise.
- Flame Sensor Moisture Purge Before Ignition in Heating Appliances
Moisture in the combustion cabinet can trigger false flame signals, so airflow purges it before ignition to verify reliable sensing.
