Direct Carbon-Dioxide Mitigation TRIZ Cases
- Tubular Oxygen–Flue Gas Nozzle Assembly for Legacy Plants
Nested inner and outer nozzles mix pure oxygen with recirculated flue gas to support low-nitrogen CO₂ capture in legacy plants.
- Oxygen Preheating in Oxyfuel Combustion via Indirect Heat Exchange
Indirect heat exchanger preheats oxygen using recirculated flue gas, eliminating steam preheaters and preventing oxygen leakage into the carbon dioxide stream.
- Recirculated-Suspension Pre-Calciner for High-Concentration CO2 Capture
A recirculated-suspension pre-calciner system utilizes vortex cyclone separation and oxy-combustion to concentrate flue gas.
- Regenerative Rotary Preheater Oxygen Leakage Prevention
An oxygen flow passage positioned between primary and secondary combustion support fluid channels prevents direct leakage to the flue gas side.
- Dynamic Measurement Cycle for CO2 Sensor Battery Life
A carbon dioxide concentration circuit adjusts measurement intervals based on predicted gas levels to extend primary battery operation.
