摘要： A device for cleaning inner surfaces of heat exchanger tubes (1) according to the present invention is disclosed, in which a pair of main cleaning device bodies (4) each having a moving device (5) and a brush driving device (7) are disposed on opposite tube plates (2) on which each opened end of the heat exchanger tubes (1) is disposed, at least one of the pair of main cleaning devices is provided with a cleaning brush changing device (9), and each brush driving devices (7) is made to correspond to the opened end of the same heat exchanger tube (1) so that pressurized fluid is alternately supplied to each of the corresponding brush driving device (7) from a pressurized fluid supplying unit (11) and thereby a cleaning brush (3) is moved. As a result of this, only one cleaning brush (3) can clean a multiplicity of heat exchanger tubes (1). Furthermore, since a brush changing device (9) is provided, the cleaning brush (3) can be at need replaced by fresh one so that a further number of heat exchanger tubes (1) can be cleaned.

摘要： An apparatus for collecting cleaning bodies in a tubular heat exchanger is disclosed which rectifies or regulates the deflected flow of the cooling water from the upstream side by a rectifying member (5), and hence it is possible to collect the cleaning bodies without any adhesion and stagnation of the cleaning bodies in the cooling water on collection lattices (2) disposed in a V-shape. It is also possible to trap a large article such as a falling tool between a guide member disposed downstream of the collection lattices and the collection lattices, and to introduce only the cleaning bodies into the guide member. Furthermore, the downstream port of a cleaning body discharge pipe (4) is opened toward the downstream side to thereby prevent the clogging of the port with the foreign matter or the like.

摘要： To watch the performance of a condenser, cooling water temperature, cooling water flow rate, condenser temperature and/or heat flux through walls of cooling water tubes of the condenser are sensed by sensors (16,18,19,20,21,22,23,24) to obtain values representing the operating conditions of the condenser. The overall heat transmission coefficient or heat transfer rate of the cooling water tubes is calculated by an arithmetic unit from these values. The cleanness of the cooling water tubes is calculated by an arithmetic unit from the overall heat transmission coefficient or heat transfer rate, and the performance of the condenser is judged by a performance judging unit based on the cleanness of the cooling water tubes. Good and continuous monitoring of the condenser can be achieved.
