Abstract
A heating system can include a supply piping assembly configured to supply either a first fuel or a second fuel to at least one main burner, a first pilot burner and a second pilot burner. First and second electromagnetic valves can be operatively connected to an electrical power supply and at least one of the thermocouples. The first and second electromagnetic valves can be configured to permit and prevent the fuel from reaching at least one of the first pilot burner, the second pilot burner and the at least one main burner depending upon thermoelectric potential received from the at least one of the thermocouples.
Claims24
A heating system capable of generating heat when supplied with either a first fuel or a second fuel, the system comprising:
- at least one main burner configured to generate heat, the at least one main burner receiving the fuel through at least one of a first inlet and a second inlet;
- a first pilot burner including at least one thermocouple;
- a second pilot burner including at least one thermocouple;
- a supply piping assembly configured to supply either the first fuel or the second fuel to the at least one main burner, the first pilot burner and the second pilot burner;
- an electrical power supply;
- and
- first and second electromagnetic valves each operatively connected to the electrical power supply and at least one of the thermocouples, the first and second electromagnetic valves being configured to permit and prevent the fuel from reaching at least one of the first pilot burner, the second pilot burner and the at least one main burner depending upon thermoelectric potential received from the at least one of the thermocouples,
- wherein:
- the first electromagnetic valve is operatively connected to the at least one thermocouple of the first pilot burner, the first electromagnetic valve being configured to permit or prevent the fuel from reaching the first pilot burner depending upon thermoelectric potential received from the at least one thermocouple of the first pilot burner;
- and
- the second electromagnetic valve is operatively connected to the at least one thermocouple of the second pilot burner, the second electromagnetic valve being configured to permit and prevent the fuel from reaching the second inlet depending upon thermoelectric potential received from the at least one thermocouple of the second pilot burner.
A method of operating a heating system, the method comprising:
- receiving a first fuel;
- igniting the first fuel;
- receiving thermoelectric potential from a first thermocouple in response to the first fuel being ignited;
- causing a first electromagnetic valve to be maintained in an open position in response to the thermoelectric potential received from the first thermocouple;
- allowing a second electromagnetic valve to move to an open position based on the absence of thermoelectric potential received from a second thermocouple;
- receiving a second fuel;
- igniting the second fuel;
- receiving thermoelectric potential from the second thermocouple in response to the second fuel being ignited;
- causing the second electromagnetic valve to be maintained in a closed position based on the thermoelectric potential received from the second thermocouple;
- and
- allowing the first electromagnetic valve to move to a closed position based on the absence of thermoelectric potential received from the first thermocouple.
