摘要： An apparatus for and method of rapidly detecting a flame out condition. A thermopile receives heat energy from the flame and generates electrical power to enable operation of a microprocessor. This microprocessor periodically measures the output voltage of the thermopile at one second intervals. An average is taken of eight consecutive samples. A running history of eight averages is stored within a FIFO which serves as a history queue. This FIFO thus stores a digitized signature of the flame condition over the previous 64 seconds. Analysis by the microprocessor is able to make an early detection of the flame out condition be utilizing the current voltage measurement sand the FIFO contents.
