Abstract

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.
