Failure diagnosing apparatus for combustion systems
First Claim
1. In a combustion system wherein a fuel jetted out from a burner is ignited and caused to produce flames in a predetermined sequence, an apparatus for diagnosing failures in the combustion system in its entirety or in some of component devices of the combustion system, the failure diagnosing apparatus comprising:
- means for measuring different items of measurement data representing the behavior of each component device of the combustion system during the operation of the system in the predetermined sequence,a diagnosis knowledge base having stored therein as knowledge data the causal relation of different kinds of failures to causes which failures can occur in one or a plurality of component devices to be inspected for diagnosis, in connection with the different items of measurement data to be obtained from the measuring means, andknowledge base drive means for driving the diagnosis knowledge base based on the measurement data obtained from the measuring means and deriving diagnosis data as to the causes of failures.

Abstract
An apparatus 9 for diagnosing failures in the combustion system to be installed in the regenerator of an absorption chiller is adapted to automatically prepare quantitative diagnosis data from a plurality of items of measurement data. The apparatus comprises an abnormality degree calculating circuit 2 for calculating degrees of abnormality serving as indexes for discriminating failures, from different items of data obtained by a combustion system control unit 1, a binary conversion circuit 4 for converting the abnormality degrees obtained from the circuit 2 to binary data representing "normal" or "abnormal," a condition judging circuit 5 for discriminating types of states of failures from the binary data by driving a diagnosis knowledge base 7, and a diagnosis data calculating circuit 6 for calculating diagnosis data from the abnormality degrees and types of failure states by driving the base 7.
