Abstract
In certain embodiments, an apparatus can comprise a dual fuel pilot assembly. The pilot assembly can comprise a first fuel dispenser, a second fuel dispenser, an igniter and at least one of a thermocouple, and a thermopile. The pilot assembly can be configured to direct heat from combustion of one of either a first fuel or a second fuel to the at least one of the thermocouple and the thermopile.
Claims18
An apparatus comprising:
- a dual fuel pilot assembly, said pilot assembly comprising:
- a first fuel dispenser configured to deliver a first fuel;
- a second fuel dispenser configured to deliver a second fuel different from the first fuel;
- and
- at least one of a thermocouple configured to couple with a feedback line and a thermopile configured to couple with a power line;
- wherein heat from combustion of either the first fuel or the second fuel is directed toward the at least one of the thermocouple and the thermopile;
- and a valve assembly comprising:
- a housing having a first flow path and a second flow path therethrough;
- a valve core positioned within the housing and having a first position and a second position;
- and
- an integral nozzle assembly having a first nozzle outlet and a second nozzle outlet;
- wherein the first position of the valve core allows flow through the valve assembly along the first flow path and through the first nozzle outlet, the second position of the valve core allows flow through the valve assembly along the second flow path and through the second nozzle outlet.

An apparatus comprising:
- a pilot system, said pilot system comprising:
- a first fuel dispenser configured to be in fluid communication with a first pilot delivery line;
- and
- a second fuel dispenser configured to be in fluid communication with a second pilot delivery line;
- an igniter configured to connect to an igniter line;
- and
- at least one of a thermocouple configured to connect to a feedback line, and a thermopile configured to connect to a power line;
- wherein the pilot system is configured to direct heat from combustion of one of either a first or a second fuel to the at least one of the thermocouple and the thermopile, the first fuel configured to flow through the first fuel dispenser and the second fuel configured to flow through the second fuel dispenser;
- and
- a valve assembly comprising:
- a housing having a first flow path and a second flow path therethrough;
- a valve core positioned within the housing and having a selectable first position and second position within the housing;
- and
- an nozzle assembly integral with the housing having a first nozzle outlet and a second nozzle outlet;
- wherein the first position of the valve core allows flow through the valve assembly along the first flow path and through the first nozzle outlet, the second position of the valve core allows flow through the valve assembly along the second flow path and through the second nozzle outlet.
