Heat transfer tube monitoring apparatus

摘要

According to the present invention, a heat transfer tube monitoring apparatus for use in a heat exchanger including multiple-stage heat transfer tube bundles (11a, 11b, 12a, 12b, 13a, 13b) spaced apart from each other in a flow direction of flue gas includes a differential pressure detecting unit used for detecting a differential pressure between upstream and downstream for each of the heat transfer tube bundles (11a, 11b, 12a, 12b, 13a, 13b). With this configuration, an abnormal heat transfer tube bundle can be specified.
