A removable inlet tube feeds dual burner ports at different fuel-air rates to lower flame temperature and cut water heater NOx emissions.
A removable inlet tube sets different fuel-air flow rates in dual burners, lowering flame temperature and NOx in tankless water heaters.
Targeted weld spots on a metal mesh burner head raise local airflow resistance to prevent flame separation and cut NOx emissions.
Welded mesh and partitioned fire ports raise airflow resistance to prevent flame separation and cut NOx in gas burners.
Segmented gas inlets eliminate flow interference between inner and outer rings, maintaining flame stability during high heat cooking.
Deforming the tube end creates a mechanical lock that eliminates threaded connections, resolving installation precision issues and gas leak risks.
Perforating the cover and aligning it with a pre-formed recess guides welding, preventing gaps that cause dangerous flame channels.
An adjustable gas grill burner uses two tubular members to adapt length and block outlet holes.
A U-shaped combustor pipe uses a reduced section to deliver gas evenly to the burner tray.
