Abstract

PURPOSE: To improve reliabilities without requiring skill by predicting future values of thermal stress of a heat exchanger outlet header and a gas-water separator by respectively appliying heat transfer rates corrected by the use of temperature distribution in thickness directions to obtain heating-up rates, pressure-rising rates and command values thereof respectively at the present time in an operation support apparatus of a steam generator etc.
CONSTITUTION: On receipt steam temperature present value signals 17 and valve-opening signals at the present time 10, 13, 18, a first arithmetic means 27 outputs steam temperature future value prediction signals 37. Based on these signals 37, arithmetic means 28, 30 successively predict quantities of heat transfer and thermal stress, whereby an arithmetic means 31 outputs heating-up rate limiting value signals 41 to an optimum control variable computing means 32. The means 32 determines deviations between heating-up target temperature signals 38 and the signals 17 to output, based on the deviations, excessive steam, discharge valve actuation signals 10, fuel flow control valve actuation signals 13 and excessive steam feed valve actuation signals 18 within the range of the signals 41. In this manner, reliability can be improved without requiring skill.
