【 摘 要 】

Based on the equivalent heat drop theory, the calculation method of the influence of the relative internal efficiency change of steam turbine cylinder on heat loss is proposed. The numerical results show that the method can more accurately evaluate the effect of efficiency change of each cylinder on heat loss, and provides a theoretical basis for the thermal economic diagnosis of steam turbine.
