摘要
Abstract
Along with the great capacity units with high valued parametersdiving into electric power production, a Mitsubishi 700 MW unit, designed for high operating efficiency and maximum reliability, has been installed in Zhuhai Power Station. The rational and optimal start-up procedure of the turbine makes the least need of time for a cold start-up with the least life consuming. Aiming at thermal stresses of the high and intermediate pressure (HP-IP) rotor, the start-up procedure of this unit is introduced. A new conception called gray boundary, concerning the conflict between each experiential formulas of heat transfer coefficient, is presented to obtain the temperature filed and the thermal stress field using finite element method (FEM). It is obvious that the interval value can express the thermal stress in a much better way.关键词
