A insert for a staged fuel burner and processes for using a burner with the insert. The insert has a burner tip that injects a mixture of primary fuel and combustion air into a combustion zone to produce a flame. A staged fuel is also injected into the combustion zone. Prior to being injected into the combustion zone, from the burner tip, the staged fuel, is injected into the burner tip and draws combustion air from the mixer of the burner insert into the burner tip with the staged fuel.

An innovative oxyhydrogen (HHO) burner system including one or more burner systems is provided to eliminate emissions through total combustion. Each burner system includes at least one HHO gas supply and an external natural gas supply, both of which are connected to a gas mixer. A controller regulates the amounts of incoming HHO gas and the natural gas through being mixed. The mixed gas is supplied to each burner assembly with a predetermined pressure and flowrate to generate a flame for the total combustion of the exhaust stream inside the exhaust pipe. With feedback from an exhaust measuring system inside the exhaust pipe adjacent the outlet, the controller can adjust the burner system for optimal operations and achieve total combustion. Thus, by passing the exhaust or gases through a substantial cross-section covered by each flame, emissions can be greatly reduced or eliminated.

A gas burner controller adapter for use in adapting a gas burner control device, which is configured to be connected to a flame ionization electrode and a separate ignition electrode, to operate in a gas burner that only includes a single electrode serving as both the flame ionization electrode and the ignition electrode.

A fuel burner includes a tube extending from a first end to a second end and including a central passage and fluid directing structure for directing a mixture of air and combustible fuel radially through the tube. The fluid directing structure collectively defines a total flow area. A blocking member is axially movable within the central passage between a first condition blocking a first percentage of the total flow area and a second condition blocking a second percentage of the total flow area different from the first percentage to control the flow of the mixture of air and combustible fuel through the fluid directing structure from the first end to the second end of the tube to be ignited.
