The relative internal efficiency of a stage is the ratio of the effective enthalpy drop of the stage to its ideal energy. The main factors affecting the relative internal efficiency of a turbine include changes in the structure and surface condition of the turbine’s flow passages ； Changes in the dynamic and static clearances of the flow passage section ； Changes in the turbine load, steam inlet parameters, and the opening degree of control valves, etc.
The ratio of the effective specific enthalpy drop of a stage to the ideal energy is called the relative internal efficiency of that stage, commonly referred to as stage efficiency. The main factors affecting the relative internal efficiency of a turbine are: the relative internal efficiency of a turbine reflects the degree of perfection and operating condition of the flow passage section of the unit. The main factors affecting the relative internal efficiency of a turbine include changes in the structure and surface condition of the turbine’s flow passages ； Changes in the dynamic and static clearances of the flow passage section ； Changes in the turbine load, steam inlet parameters, and the opening degree of control valves, etc.
The ratio of the effective specific enthalpy drop of a stage to the ideal energy is called the relative internal efficiency of that stage, commonly referred to as stage efficiency. The relative internal efficiency of a stage indicates the degree of perfection in energy conversion within that stage, and it is an important indicator for assessing the economic efficiency of a stage. Its value depends not only on the type of stage, as well as the blade profile, reaction degree, speed ratio, and blade height, but also on the properties of the steam and the structural characteristics of the stage
The ratio of the effective specific enthalpy drop at a given stage to the ideal energy is known as the relative internal efficiency of that stage, or simply stage efficiency. The relative internal efficiency of a stage indicates the degree of perfection in energy conversion within that stage, and it is an important indicator for assessing the economic efficiency of a stage. Its value depends not only on the type of stage, as well as the blade design, reaction degree, speed ratio, and blade height, but also on the properties of the steam and the structural characteristics of the stage
It refers to the ratio of the effective enthalpy drop per stage to the ideal energy per stage
The ratio of the effective enthalpy drop within the turbine to its ideal enthalpy drop is called the relative internal efficiency. The main factors affecting this value include changes in the structure and surface condition of the turbine’s flow passages； Changes in the dynamic and static clearances of the flow passage section ； Changes in the turbine load, steam inlet parameters, and the opening degree of control valves, etc.
The ratio of the effective specific enthalpy drop of a stage to the ideal energy is called the relative internal efficiency of that stage, commonly referred to as stage efficiency. The relative internal efficiency of a stage indicates the degree of perfection in energy conversion within that stage, and it is an important indicator used to assess the economic efficiency of a stage. Its size is determined not only by the type of stage, the selected blade profile, specific impulse, speed ratio, and blade height, but also by the properties of the steam and the structural characteristics of the stage.
