循环流化床锅炉屏式过热器改造
摘要
针对华电六安发电有限公司2×135MW机组循环流化床锅炉屏式过热器管壁超温和变形问题
提出了在屏式过热器原有耐磨耐火可塑料的基础上呈梯形再包敷不同高度的耐磨耐火可塑料
以减少诸管段的吸热量
降低壁温。改造后
基本解决了屏式过热器管壁超温和变形问题
提高了锅炉的安全性和经济性。
Abstract
Directing against the problems of tube-wall overtemperature and deformation on platen superheater of CFB boilers for 2×135 MW untis in Huadian Lu'an Power Generation Co Ltd
retrofit measures have been put forward as follows:On the basis of abraision-resistant and fire-resistant plasticable material on the original platen superheater
new abraision-resistant and fire-resistant placticable materials with different heights have been cladded according stair rise mode
to reduce the absorbed heat of the tube sections
lowering the tube-wall temperature.After retrofitting
the above-mentioned problems on the platen superheater have been basically resolved
enhancing safety and economic efficiency of the boilers.
