摘要:
对正压浓相气力输灰系统的输灰管道的管径选择进行了研究。分析了影响输灰管道的管径选择的众多因素，采用理论与实际工程相结合的方式，利用理论上的公式推导和60个工程的实际统计数据进行研究，确定了关键参数的计算方法。并建立了相关的数学模型，最终得出了可用于指导工程设计的管径计算经验公式。为以后燃煤电厂正压浓相气力输灰系统的输灰管道管径选择提供了设计选型依据，填补了这方面的空白，具有重要的借鉴参考意义。 Abstract:This paper researches on pipe diameter selection of dense phase positive pressure pneumatic fly ash handling system. The influencing factors are discussed, and an approach based on theoretical analysis and data of 60 running projects is taken to determine several key parameters. A mathematical model is built to develop an empirical formula for pipe diameter selection. The paper, which fills in a gap on this area, has an important reference significance for engineering design.
