Chimneys TRIZ Cases

A 360-degree venturi channel creates low pressure above the exhaust port, extracting tank gases even under low air movement.

A closed side space routes hot exhaust gas to heat the partition wall early, reducing acid drain formation and scattering at startup.

Telescoping side panels let one chimney shroud fit different chase sizes on-site, cutting custom fabrication and misfit risk.

A pulley and tether let users open or close a sealed chimney damper more easily, improving ventilation control and reducing heat loss.

Arc-shaped slots and a removable precast concrete door create a tight, corrosion-resistant chimney cleanout that stays accessible for ash removal.

Constricted intake openings create a positive-pressure zone in a chimney termination to stop exhaust backflow and maintain combustion air supply.

A flue gas channel uses wall openings and closing devices to remove catalysts and dust separators for cleaning and reconditioning.

A segmented chimney closure device uses an inner lid, insulating element, and outer cover to seal exhaust ducts.

Circular arc pipe bend reduces chimney cross section and weight, resolving installation constraints in existing chimneys.

Segmented internal fitting seal enables single-person installation through wall openings, eliminating external access requirements.

A marine exhaust device channels hot gas around the flue to create a rotating peripheral stream that delays condensation.

Elastic sensing member detects exhaust flue pipe separation from the adapter, preventing toxic gas leakage and enhancing boiler reliability.

Pre-molded UV-stabilized PVC flue cap covers eliminate post-installation painting, resolving color coordination bottlenecks for large buildings.

An air supply and exhaust adapter uses negative gauge pressure to redirect combustion gases through a communication passage.

A modular kit system produces flush-mounted chimney door devices using a common frame structure for inspection and cleaning access.

Alternating solid and perforated sidewall segments in a chimney cap separate exhaust and fresh air intakes, preventing water and debris accumulation.

A chimney termination cap uses a tray and drainage aperture to collect and remove precipitation from the assembly.

Nested tubular parts telescope into each other, reducing packaging volume while maintaining structural integrity for roof installation.

An insulating layer on the central tube limits condensation and bistre formation, maintaining reliable fume evacuation in wood-burning heaters.

An integrated connecting ring joins flue pipe sections while establishing electrical continuity, preventing gas leakage from unstable connections.

An adjustable channel system with base supports and a collar protects protruding chimney pipes from environmental wear without replacing the entire structure.

Universal attachment elements on the orientation body enable multiple configurations, reducing system complexity while maintaining installation flexibility.

Segmented cover elements nest to reduce safety distances from combustibles while accommodating varying duct lengths.

Movable coupling pieces allow pipe segments to expand and contract freely, preventing stress-induced leaks during flue gas temperature changes.

Movable pipe sections with integrated electrical conductors allow adjustable flue lengths while maintaining stable mechanical and electrical connections.

Segmented tubular bodies connect via tabs to adjust stack length, reducing fabrication and shipping costs.

Inclined contact surface prevents resin adhesion, enabling easy disassembly without mechanical aids.

A tubular coupling piece integrates a fluid collection channel to guide condensate along the peripheral wall.

A flue pipe mounting structure uses a flexible EPDM seal to accommodate lateral and longitudinal movement of the conduit.

A gas appliance system uses a switch assembly to verify flue pipe installation.

Nested rainproof segments with downward openings simplify installation while preventing water ingress.
