摘要
Abstract
For the 300-MW subcritical boiler in a power plant, the steam temperature at the outlet of the reheater has always been lower than the designed value after the turbine through-flow transformation. Through the analysis on the data from the reheat steam temperature adjustment test, it is observed that the steam temperature at the inlet of the reheater is much lower than the designed value. Based on the thermal balance calculation, three schemes for increasing the capacity of the reheater are proposed. After comparison, the most reasonable one is selected and put into practice. The performance test after the transformation indicates that the reheat steam temperature at the outlet of the reheater is improved significantly, reaching the designed value of 541℃ with the economic efficiency of the plant also improved greatly.关键词
