摘要： In a cleaning system for heat conductive conduits of a heat exchanger, a great number of balls are circulated through the conduits for mechanically removing incrustations formed on the inner surfaces of the conduits. In order to automatically operate the cleaning system, there are provided with ball counters, one of which counts the number of balls actually circulating the system and the other count the number of balls to be withdrawn out of the system or replaced with new balls because of worn out or breakage. The number of balls circulating is always maintained at a certain level necessary for effective cleaning by a controller which actuates various valves to maintain the number of balls in response to the signal generated by the ball counters.

摘要： A method of monitoring the performance of a condenser and a system for carrying such method into practice, wherein a cooling water temperature, a cooling water flow rate, a condenser temperature and/or a heat flux through walls of cooling water tubes of the condenser are sensed by sensors to obtain values representing the operating conditions of the condenser, and an overall heat transmission coefficient or a heat transfer rate of the cooling water tubes is calculated at an arithmetic unit from the values representing the operating conditions. The cleanness of the cooling water tubes is calculated by an arithmetic unit from the value of the overall heat transmission coefficient or the 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.

摘要： A foreign matter removing apparatus for removing foreign matters from cooling water such as sea water taken as the cooling water for the condenser of, for example, a power generating plant. The apparatus has an inversed frusto-conical barrel, a filter of a substantially same form as the barrel and disposed in the latter, a cooling water inlet pipe connected to a side portion of the barrel, a cooling water outlet pipe connected to an upper portion of the barrel, a foreign matter discharge pipe connected to a lower side portion of the barrel, and a butterfly valve disposed in the cooling water inlet at which the cooling water inlet pipe is connected to the barrel. The foreign matter discharge pipe is periodically opened while varying the opening degree or angular position of the butterfly valve thereby to remove and discharge foreign matters from the filter surface. The filter is provided at an upper portion thereof with a cover plate or, alternatively, non-perforated portion which effectively enhances the foreign matter removing ratio while eliminating the clogging of the filter and reducing the pressure drop.

摘要： Method and apparatus for removing extraneous matters from cooling water used in a tubular heat exchanger such as a condensor is disclosed. When a pressure difference between the portions upstream and downstream of a filter element exceeds a predetermined threshold value set in advance in accordance with the flow rate of the cooling water, a blow-down operation is started to remove the extraneous matters scraped off of the outer peripheral surface of the filter element by a turning flow. The extraneous matters are removed at a rate of clogging of the filter element of 50%, irrespective of the flow rate of the cooling water. The clogging rate can be sensed accurately, and the blow-down operation is effected with necessary and sufficient frequency.

摘要： An apparatus for collecting cleaning bodies in a tubular heat exchanger capable of collecting the cleaning bodies with a high collection efficiency against the temporary introduction of a large amount foreign matter such as falling tools in a cooling water system and against the deflected flow of the cooling water from the upstream side. A rectifying member rectifies or regulates the deflected flow of the cooling water from the upstream side whereby it is possible to collect the cleaning bodies without any adhesion and stagnation of the cleaning bodies in the cooling water on V-shaped collection lattices. 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 opens toward the downstream side to thereby prevent the clogging of the port with the foreign matter or the like.

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