Apparatus for recovering floating hard-body tube cleaning elements from cooling water downstream of a heat exchanger. The floating hard-body tube cleaning elements are removed from the water flowing through a cooling tower distribution header and recovery from a modified distribution header vent.

An apparatus for cleaning heat exchanger tubes and in particular an improved collection system for nuclear generator cleaning and blasting media and deposit material. A suction line having a downwardly directed suction inlet is effective to vacuum airborne media and debris in said chamber and vacuum media and debris deposited on the bottom of said chamber below said suction inlet. A hopper, air jet and shaker means are provided to transport deposited media and debris toward the suction inlet. Br...

A system for cleaning the inside of tubing, as of a heat exchanger, which is made up of a number of balls entrained by a liquid flowing through the system, a separator for separating the balls from the liquid downstream of the tubing, an accumulator for accumulating the balls downstream of the separator, a storage tank for storing a volume of injection liquid, and a mechanism for injecting the balls upstream of the tubing by displacement of the injection liquid from the storage to upstream of th...

The present invention relates to a heat exchanger comprising a plurality of parallel-oriented plates or layers securely fixed between two outer walls or frames to define between adjacent plates an area of sealed passages for two heat exchanging fluids, channel or duct means for conducting a hot medium and a cold medium respectively over the layers such that the flow of hot and cold medium takes place in an in-line and a counter-flow fashion, and an external return bend means providing a transfer...

The present invention relates to a method for more efficiently operating a heat exchanger wherein heat is exchanged between a scale-forming and a scale-cleaning liquid. The scale-cleaning liquid is passed periodically into the region of the heat exchanger wherein scale from the scale-forming liquid has accumulated, and the effluent is flushed from the heat exchanger.

An apparatus removing material accumulated on the exterior surfaces of adjacent heat exchanger plates arranged side-by-side in a spaced relationship in a bulk material heat exchanger and a bulk material heat exchanger incorporating the apparatus is provided. In one aspect, the apparatus develops vibratory shock waves through each coil to dislodge material that has accumulated on the surfaces of the heat exchanger plates. In another aspect, the apparatus translates each heat exchanger plate in a ...

A method and an apparatus are provided for the operational monitoring of a condenser including a steam chamber through which steam to be condensed flows and at least one configuration having a plurality of tubes in the steam chamber through which a coolant fluid passes from an inlet to an outlet end. The steam pressure and/or temperature is measured at least at one measuring point in the steam chamber. In addition, the inlet temperature of the coolant fluid at the inlet end, the outlet temperatu...

A recuperator-type heat recovery apparatus may have a configuration for passing hot waste gases through an elongate, extended cyclone-type circulation path within a constricted area effecting the flow of the gases against a heat transfer surface and providing an extended retention time for radiating and conducting heat into this heat transfer surface and concurrently for changing the velocity of the gases resulting in a separation or fallout of heavier particles of dust and other matter entraine...

An apparatus for measuring a fouling resistance and a cleanliness factor of heat-transfer surface and which is capable of continuously and accurately monitoring a build-up degree of deposits on a heat-transfer surface of a heat exchanger includes a fouling sensor having a given length of metal wire wound inside the heat-transfer surface for measuring an average temperature of the heat-transfer surface, a direct current voltage supply member for supplying a voltage to a heating wire of the foulin...
