How is the cylinder of a steam turbine supported? 2020-03-25


The cylinder of the steam turbine is generally made into a horizontal bisection type, which is divided into an upper cylinder and a lower cylinder.

 

In order to make reasonable use of steel, small and medium-sized steam turbine cylinders are often divided into high pressure section, medium pressure section and low pressure section with one or two vertical joint surfaces.

 

High-power steam turbines are equipped with high-pressure cylinders, medium-pressure cylinders, and low-pressure cylinders according to their operating characteristics.

 

After adopting double-layer cylinder structure for high pressure and high temperature, the cylinder is divided into inner cylinder and outer cylinder.

 

The steam turbine's last stage blade will discharge steam into the condenser later. This part of the cylinder is called exhaust cylinder.
