介绍了蒸汽喷射泵的结构和性能,分析了几种不同的评价方法,并且试用的分析方法,构造出该装置的流图并进行装置的热力经济性分析,在该装置的性能分析计算中尚属首次,该方法简洁、直观、结论正确,最后以某电厂的具体工程运行中的装置为例,对其性能进行了分析,并且比较了改造前的换热器系统性能,为热力系统中的设备、装置的选用提供了理论和现实的依据和实例。 The structure and performance of the steam jet pump are introduced. Several different evaluation methods are analyzed, and the analysis method of the steam turbine is analyzed to construct the flow chart of the steam turbine and to analyze the thermal economy of the steam turbine. In the performance analysis of the device, For the first time in calculation, the method is concise and intuitional, and the conclusion is correct. Finally, taking a plant in a specific project as an example, its performance is analyzed, and the performance of the heat exchanger before reform is compared with that of the heat The selection of equipment and devices in the system provides theoretical and practical basis and examples.
