摘要： An improved multi-section heat exchanger unit for use in combination with a radiant furnace unit or direct fired heaters which comprises a first heat exchange section having a plurality of bare heat exchange pipes positioned therein and in fluid communication with a first heat exchange fluid inlet and a first heat exchange fluid outlet to provide fluid flow through the bare pipes; and a second heat exchange section having a plurality of extended surface heat exchange tubes positioned therein in fluid communication with a second heat exchange fluid inlet being in fluid communication with the outlet of the first heat exchange section, the second heat exchange section being further characterized as having a gradually reduced internal cross section towards its upper portion so that the velocity of gas flow therethrough is maintained substantially constant.In one embodiment a third heat exchange section having a plurality of extended surface heat exchange tubes positioned therein is provided wherein the tubes are in fluid communication with the tubes of the first and second heat exchange sections.

摘要： A method for killing zebra mussels from a bottom surface of a waterway and from the surfaces of watercraft, docks, pilings and similar facilities located within a waterway. The surfaces to be treated are isolated in a batch of water enclosed within a chamber. The isolated batch of water is thereafter heated to a temperature lethal to the zebra mussels and held at that temperature for a sufficient time to kill the zebra mussels. The isolated batch of water and the treated surface are thereafter released from the chamber and the isolated state.

摘要： A method and apparatus for controlling zebra mussels in the inlet cell of a utility power plant by isolating a batch of water in the cell from the water supply of a lake or river and the equipment plant by shutting an inlet gate and shutting outlet valves from said cell. The batch of isolated water is thereafter heated to a lethal temperature which is maintained for a sufficient period of time to ensure 100 percent mortality to the zebra mussels within the cell. The water may be maintained in a static condition and heated by a heat exchanger disposed within the cell. Alternatively the water may be fed to a heat exchanger, heated outside the cell, and returned to the cell. The water is heated to a range of approximately 95.degree. F. to 100.degree. F. and held at the heated temperature within the cell for approximately 30 minutes.
