摘要： A thermal power plant having multi-staged steam turbines and heat exchangers therebetween, each heat exchanger extracting heat from the supply to an upstream stage for adding heat to the supply of the next successive downstream stage; a portion of the supply to the last downstream stage being diverted through a heater for adding heat to the feedwater flow to a boiler. Additional heat exchangers may be provided between stages for utilizing the feedwater to cool the working steam. One form of heat exchanger is provided with a plurality of axially spaced annular chambers having vortex flow producing means adjacent the inner peripheries thereof; whereas another form of heat exchanger is provided with a helically finned interior chamber in fluid communication with upstream guide vanes for inducing vortex flow.

摘要： A multitubular heat exchanger used in a power plant is provided with a bundle of U-shaped heat transfer tubes and a vent tube. The vent tube is located between an upper portion and a lower portion of the bundle of U-shaped heat transfer tubes. A steam flow guide plate is located above a hole of the vent tube and below the upper portion of the bundle of U-shaped heat transfer tubes. The steam flow guide plate obstruct a downward steam flow from the upper portion of the bundle toward the vent tube.

摘要： In a steam engine, an intermediate phase is provided for preheating the feedwater before it enters the boiler. The preheating is achieved by means of the reapplication of the otherwise dispensable exhaust steam in a simple feedback operation in which the exhaust steam is introduced directly into the feedwater. By means of electronic controls the operation of the system at the highest possible point of preheat (up to 210.degree. F.) is achieved thus assuring both high efficiency of the machine and cumulative economy in fuel consumption as well. The latter is further augmented by generous application of insulation to prevent wasteful dissipation of thermal energy as well as to effect protection of the system against the elements.

摘要： A feedwater heater for use in a power plant system in which steam from another unit in the system is introduced into the shell of the heater and the latter discharges condensate to another unit in the system. Feedwater to be heated is circulated through tubes in the shell in heat exchange relation to the steam whereby a portion of the steam is condensed. Another portion of the steam is directed to an area of the shell where it warms the condensate to a degree that maintains the condensate at or near its saturation temperature. An additional inlet is provided in the shell for receiving condensate from another unit of the system along with means for breaking up the flow of the latter condensate to promote deaeration as a portion of the condensate flashes into vapor. The vapor produced as a result of the flashing is directed in the same flow path as the above-mentioned steam, and vent means are provided for permitting the removal of the non-condensibles and associated water vapor from the shell.
摘要翻译： 一种用于发电厂系统的给水加热器，其中来自系统中的另一单元的蒸汽被引入加热器的壳体，而后者将冷凝物排出到系统中的另一个单元。 待加热的给水以与蒸汽热交换的方式循环通过壳中的管，由此蒸汽的一部分被冷凝。 蒸汽的另一部分被引导到壳体的一个区域，在那里它将冷凝物加热到将冷凝物保持在或接近其饱和温度的程度。 在壳体中设置另外的入口，用于从系统的另一个单元接收冷凝物，以及用于分解后者冷凝物的流动以促进脱水的装置，因为冷凝物的一部分闪蒸成蒸气。 由于闪蒸而产生的蒸气被引导在与上述蒸汽相同的流动路径中，并且设置排气装置以允许从壳体去除不可冷凝物和相关联的水蒸气。
