摘要

在电厂中，再热器出口汽温一直低于设计值。对电厂两台亚临界、中间再热和自然循环锅炉进行了再热汽温调节试验。通过对试验数据的分析，找出了再热汽温过低的原因。提出了三种再热器增能改造方案并进行了比较，选出了最合理的方案。本文的研究为解决同类型锅炉的类似问题提供了有益的经验。

Scheme analysis of capacity-increasing transformation for reheaters of 300MW boilers in a power plant

The steam temperature at the outlet of the reheater has always been lower than the designed value in a power plant. A reheat steam temperature adjustment test was conducted on the two subcritical, intermediate reheat and natural circulation boilers in the power plant. By analyzing the test data, reasons of the low reheat steam temperature have been discovered. What's more, three schemes about capacity-increasing transformation for reheaters have been proposed and compared, after which the most reasonable one is selected. What is studied in the paper provides helpful experiences in solving similar problems for boilers of the same type.
