Hydrogen/Oxygen Torch Ignitor

Abstract

Reliable device used to ignite variety of fuels. Used as general-purpose ignitor in other applications, or as hydrogen/oxygen torch. Operation of device straight-forward. Hydrogen and oxygen flow through separate ports into combustion chamber in device, where they ignite by use of surface-gap spark plug. Hot gases flow from this combustion chamber, through injector tube, into larger combustion chamber containing fuel-oxidizer mixture to be ignited.
