In steam turbines, what is the difference between an inner casing and a blade carrier?

In steam turbines, what is the difference between an inner casing and a blade carrier?

(OP)
It is my understanding that both have stationary blades, and both hold the rotor up. Is there a difference in their function in a steam turbine?

RE: In steam turbines, what is the difference between an inner casing and a blade carrier?

Hopefully the link below works. If it does, take a good look at the simplified image of the turbine. You'll see two inner casings (one high pre4ssure, one low pressure) and a blade carrier. The inner casings are between the moving blades (high- or low-pressure section) and the turbine "shell" and act as a seal.

The blade carrier is similar, except it provides the sealing for the non-moving blades (usually the last three or four) in the low-pressure section.
