Burner Noise Abatement TRIZ Cases
- Concentric Air Supply Silencer for Compact Premix Heaters
Concentric pipe sections deflect combustion air to cut heater intake noise while fitting compact housings and supporting stable combustion.
- Heating Air Inlet Check Valve Layout for Exhaust Backflow
Placing the check valve upstream of the venturi avoids heat and condensate exposure while the control line offsets pressure drop.
- Perforated Burner Surface for Stable Hydrogen Combustion
Varying through-hole diameters and lengths in a perforated burner surface damp thermoacoustic pulsing and stabilize hydrogen-rich heating flames.
- Heating Device Silencer for Waste Heat Recovery and Component Protection
This heater uses a cylindrical silencer to recover combustion waste heat in the air supply while shielding heat-sensitive components.
- Flare Burner Noise Suppression via Packed Bed and Swirling
A flare burner uses a packed bed of granular material to reduce gas velocity and suppress noise while maintaining stable combustion.
- Fuel Nozzle Rotation Element Balances Flow and Reduces Acoustic Resonance
A rotation element with turning vanes pre-rotates fuel flow upstream of a sharp bend to achieve balanced distribution.
- Wing Vaned Flame Shaper for Heat Exchanger Impingement
Turning vanes induce swirl in the flame path, reducing turbulence and heat exchanger impingement while lowering noise.
- Combustion Plate Flame Hole Arrangement Stability
Bottomed holes at hexagon centers stabilize premixed gas flow, resolving high-load resonance while maintaining low passage resistance.
- Burner Distribution Diaphragm for Uniform Fuel Gas Flow
A burner distribution diaphragm creates a tentacular opening to guide fuel gas across the diffuser wall.
- Burner Hatch Baffle for Uniform Fuel Distribution
- Conical Burner Heat Distribution and Noise Reduction
A conical burner directs heat evenly toward the heat exchanger through its protruding taper design.
