Abstract:
An exhaust gas analyzing system makes it possible to determine appropriate maintenance timing of sampling pumps in the system, including sampling pumps and provided in a main flow path in order to sample exhaust gas sent from an introduction port, analysis parts provided on the upstream side or downstream side of the sampling pumps and in the main flow path, flow meters provided on the upstream side or downstream side of the analysis parts in the main flow path, and pump abnormality determination parts and for determining abnormality of the sampling pumps by comparing pump flow rates obtained by the flow meters to a predetermined abnormal flow rate.
