Exhaust gas analyzing apparatus, exhaust gas analyzing system and method of operating the same

摘要

An exhaust gas analyzing apparatus includes analyzer main bodies, exhaust gas introducing parts for guiding the exhaust gas from an exhaust pipe, through which the exhaust gas passes, to the analyzer main body, heaters for heating the analyzer main bodies and the exhaust gas introducing parts, respectively, and a temperature regulating mechanism for controlling the heaters to regulate temperatures of the analyzer main bodies and the exhaust gas introducing parts, and a first mode which has the temperature regulating mechanism regulate the temperatures of the analyzer main body and the exhaust gas introducing part to an analyzable temperature that is a predetermined temperature allowing a start of analysis of the exhaust gas, or a second mode which has the temperature regulating mechanism regulate the temperature of the analyzer main body to the analyzable temperature and turning off the heater for the exhaust gas introducing part can be selected.

主权项

1. An exhaust gas analyzing apparatus comprising:
an analyzer main body for analyzing exhaust gas; an exhaust gas introducing part for guiding the exhaust gas from an exhaust pipe passing the exhaust gas therethrough to the analyzer main body; a heating arrangement for heating the analyzer main body and for heating the exhaust gas introducing part; a temperature regulating mechanism for controlling the heating arrangement to regulate temperatures of the analyzer main body and the exhaust gas introducing part; and a mode control part configured to select between a first mode which has the temperature regulating mechanism regulate the temperatures of the analyzer main body and the exhaust gas introducing part to an analyzable temperature that is a predetermined temperature allowing a start of analysis of the exhaust gas, and a second mode which has the temperature regulating mechanism regulate the temperature of the analyzer main body to the analyzable temperature and turning off a portion of the heating arrangement arranged to heat the exhaust gas introducing part.
