The high-pressure inner cylinder is a key component used in steam turbines, mainly to provide high-pressure steam and rotational kinetic energy. The steam turbine is a kind of thermodynamic machinery, which converts heat energy into mechanical energy by inputting the high-temperature and high-pressure steam generated by fuel combustion into the blades in the steam turbine, and using the pressure and speed difference between the steam to drive the impeller to rotate.

13tThe high-pressure inner cylinder is located in the hot end of the steam turbine and is generally installed before the low-pressure inner cylinder and the medium-pressure inner cylinder. Its main function is to receive high-pressure steam from the boiler and convert its pressure and speed into the mechanical rotation energy of the impeller. When the high-pressure steam passes through the inner cylinder, the vane group is subjected to the impact force of the steam, which drives the inner cylinder to rotate and transmits the mechanical energy to the impeller of the next stage.
The design and manufacture of high-pressure inner cylinders are very demanding, as it needs to withstand high temperatures, high pressures, and high-speed rotation. Common internal cylinder materials include high-temperature alloy steel and nickel-based alloys, which have good high temperature resistance and corrosion resistance. The surface of the inner cylinder is usually coated with a special coating or thermal barrier coating to protect the inner cylinder from high temperature corrosion and wear.
