再热蒸汽系统
reheating steam system
zolre zhengq一x一tong再热燕汽系统(reheating steam system)汽轮机高压缸的排汽返回锅炉再热器再热后送回汽轮机中压缸的燕汽管道系统。若采用二级再热，则还应包括中压缸排汽再热后返回低压缸的燕汽管道系统。 从汽轮机高压缸(或中压缸)排汽口到锅炉再热器进口的蒸汽管道，称为低温再热蒸汽管道;从再热器出口到中压缸(或低压缸)的燕汽管道，称为高温再热蒸汽管道.低温再热蒸汽温度较低，管道材料通常采用优质碳素钢;高温再热燕汽温度一般与主蒸汽温度相同或略高，管道材料采用耐热合金钢。 燕汽在再热系统中的流动阻力对循环热效率的影响较大，每增加0.1 MPa的流动阻力，循环热效率将降低。.2%~。.3%.增大再热蒸汽管道和再热器的管径，虽可降低再热系统的流动阻力，但增加管道和设备的投资费用。所以，再热燕汽系统(包括锅炉再热器)的流动阻力一般限定在高压缸排汽压力的8纬~10%。 火电厂设计中，为降低再热燕汽管道的投资，通常采用提高高温再热蒸汽管道蒸汽流速的方法来减小管径，以降低耐热合金钢管材的消耗量;高温再热蒸汽管道因减小管径而增加的压力损失，可以用增大低温再热燕汽管道管径以减少压力损失来补偿。再热燕汽系统压力损失给定后，高温再热蒸汽管道和低温再热蒸汽管道的管径应通过优化计算来确定。
