Chimneys TRIZ Cases
- Omnidirectional Vent Cap for Low-Wind Tank Gas Extraction
A 360-degree venturi channel creates low pressure above the exhaust port, extracting tank gases even under low air movement.
- Exhaust Port Structure for Preventing Acid Drain Scattering
A closed side space routes hot exhaust gas to heat the partition wall early, reducing acid drain formation and scattering at startup.
- Telescoping Chimney Shroud for Variable Chase Fit
Telescoping side panels let one chimney shroud fit different chase sizes on-site, cutting custom fabrication and misfit risk.
- Pulley-Operated Chimney Damper Sealing for Heat Retention
A pulley and tether let users open or close a sealed chimney damper more easily, improving ventilation control and reducing heat loss.
- Precast Concrete Chimney Cleanout Door With Removable Arc-Slot Closure
Arc-shaped slots and a removable precast concrete door create a tight, corrosion-resistant chimney cleanout that stays accessible for ash removal.
- Chimney Termination Intake Structure for Reverse Flow Prevention
Constricted intake openings create a positive-pressure zone in a chimney termination to stop exhaust backflow and maintain combustion air supply.
- Flue Gas Channel with Removable Catalyst and Dust Separator Access
A flue gas channel uses wall openings and closing devices to remove catalysts and dust separators for cleaning and reconditioning.
