用于低温再热器的“H”型鳍片受热面及其换热方法
摘要：
用于低温再热器的“H”型鳍片受热面及其换热方法。现有的电站锅炉水平低温再热器受热面均采用光管形式。该种布置结构型式，导致低温再热器受热面布置空间偏大，不利于锅炉尾部烟道区域空间的利用并影响其他设备的布置空间，空间利用率低。本发明的组成包括：低温再热器蛇形盘管（1），所述的低温再热器蛇形盘管上焊接“H”型鳍片（2），所述的“H”型鳍片按等节距排列。本发明用于低温再热器的“H”型鳍片受热面及其换热方法。
摘要（英）：

The invention discloses an H-shaped fin heating surface applied to a low-temperature reheater and a heat exchange method of the H-shaped fin heating surface. An existing heating surface of a horizontal low-temperature reheater of a power station boiler adopts a light tube way; due to this type of structure arrangement, the heating surface of the low-temperature reheater is relatively large in arrangement space; disadvantages are caused to utilization of the area space of a tail flue of the boiler; the arrangement space of other equipment is affected as well; the utilization rate of space is low. The H-shaped fin heating surface disclosed by the invention consists of low-temperature reheater coil tubes (1), wherein H-shaped fins (2) are welded on the low-temperature reheater coil tubes and are arranged at equal pitches. The invention discloses the H-shaped fin heating surface applied to the low-temperature reheater and the heat exchange method of the H-shaped fin heating surface.
