无热网背压机组试运方法的研究

Research on the Trial Operation Method of Backpressure Turbine without Heat Supply Network

背压发电供热机组热效率高,近年来逐步为中小城市热电联产所青睐。而供热机组在建设过程中普遍存在热网建设滞后于机组建设的问题。对于背压机组来说,无热网对机组试运带来了更多的难题。本文从无热网对于机组试运带来的影响入手,分析了机组无热网所产生的一系列问题,提出了合理的试运方案。该课题的研究成果对于同类型机组的试运具有借鉴意义。

The back pressure turbine has high thermal efficiency, and it has been popular in recent years in small and medium-sized city cogeneration. But the heat supply network construction always lags behind the unit construction. To the back pressure turbine, it has some troubles on trial operation of the unit. In this paper, the study began with the effects of no heat supply network to the back pressure turbine, and analyzed a series of problems produced. Finally some reasonable trial op-eration schemes have been proposed to solve these problems. The research result has reference significance to the trial operation of the same type of unit.
