摘要:
A signal processing technique that allows the flame signal from a first source of flame and the flame signal from a second source of flame to be discriminated from each other when only both the first and second flame signals are viewed by the same flame scanner. The signal from the flame scanner is processed to enhance one or more of the attributes associated with the first flame and is simultaneously processed to enhance one or more attributes associated with the second flame.
摘要:
A method, computer program product and a system for preemptively tripping a fossil fuel fired burner of a steam generator before the burner is tripped when amplitude of any of two or more signals that represent a property of temporal combustion of the flame such as intensity or flicker frequency reaches an associated preselected signal strength. The signals that represent a property of temporal combustion are combined in a predetermined manner to give a quality signal that is used to preemptively trip the burner when the quality signal reaches a preselected signal strength.
