Abstract
A burner control system for controlling the operation of a fuel burner arranged to burn a combination of a supply of fuel and a supply of air is provided. The burner control system is arranged to receive from an exhaust gas analyzer one or more signals, each signal being indicative of the level of an exhaust gas emitted by the fuel burner; receive from a photodetector a signal indicative of a level of electromagnetic radiation output by the flame of the fuel burner; and control at least one of the supply of fuel and the supply of air to the burner based on the one or more signals received from the exhaust gas analyzer and the signal received from the photodetector.
Claims18
A burner control system for controlling the operation of a fuel burner arranged to burn a combination of a supply of fuel and a supply of air, wherein the burner control system is arranged to:
- receive from an exhaust gas analyzer one or more signals, each of the one or more signals being indicative of a level of an exhaust gas emitted by the fuel burner;
- receive from a photodetector a signal indicative of a level of electromagnetic radiation output by a flame of the fuel burner, wherein the signal received from the photodetector is a single value indicative of a total level of electromagnetic radiation output by the flame;
- determine a level of oxygen emitted by the fuel burner from the signal received from the photodetector;
- and
- control at least one of the supply of fuel and the supply of air to the fuel burner based on the one or more signals received from the exhaust gas analyzer and the signal received from the photodetector.
A fuel burner arranged to burn a combination of a supply of fuel and a supply of air, comprising:
- an exhaust gas analyzer arranged to generate one or more signals, each of the one or more signals being indicative of a level of an exhaust gas emitted by the fuel burner;
- a photodetector arranged to generate a signal indicative of a level of electromagnetic radiation output by a flame of the fuel burner;
- and
- a burner control system arranged to:
- receive from the exhaust gas analyzer the one or more signals;
- receive from the photodetector the signal indicative of the level of electromagnetic radiation output by the flame of the fuel burner, wherein the signal received from the photodetector is a single value indicative of a total level of electromagnetic radiation output by the flame;
- determine a level of oxygen emitted by the fuel burner from the signal received from the photodetector;
- and
- control at least one of the supply of fuel and the supply of air to the fuel burner based on the one or more signals received from the exhaust gas analyzer and the signal received from the photodetector.
