浅析U形管高加过热段出口汽温迭取与传热面积优化

Primary Analysis to Optimized Design of the Heat Transfer Surface and Iteration of the DSZ Outlet Steam Temperature of U-Tube High Pressure Heaters

U形管高压加热器在国内外火电机组中已得到广泛应用,高加的传热面积优化具有重要技术经济意义。本文仅就顺流传热面布置下过热段出口汽温(即过热段与凝结段分界点蒸汽温度)对于计算传热面积的影响做一初浅分析。

The U-Tube High Pressure Heaters have already been widely used at home and abroad heat-engine plant and the optimized design of the HP heat transfer surface gets important significance on technology economy.This article just gives out primary analysis about the influence of DSZ outlet steam temperature（which at the cut-off point between DSZ and DCZ） on the calculating of the heat transfer surface when it adopts downstream heat transfer surface layout.If there is anything wrong please point out.
