CRE TB Terms and Others #1

Automated sequence for starting up and preparing the Turbine for steam admission and loading up to normal operation during the startup procedure.

A rotating machine utilizing the controlled expansion of steam, and to change the thermal energy of the steam into speed energy, and convert to mechanical energy through a turbine rotor

supports and encapsulates internal steam turbine components, including the rotor, and acts as a pressure boundary containing the high-pressure steam within the steam turbine.

forged shaft containing blades to which high pressure steam is directed from nozzles onto the blades causing shaft rotation and converting thermal to mechanical energy.

Impulse __ onto which high velocity steam is directed causing the blades to move and impart rotational energy onto the rotor

outlet to convert thermal energy to have of the steam into speed energy effectively.

Controls axial movement of the turbine rotor.

turbine steam supply isolating valve with an internal bypass valve for prewarming the turbine

valve which modifies the quantity of steam, and coordinates the output of the turbine

device that operates should the turbine reach 111 percent of rated speed and prevents an inflow of the steam to a turbine.

device installed for the purpose of the backup protection of an emergency governor, the backup overspeed governor mainly operates at approximately 112 percent of rated speed.

main pump to supply for control and pressure oil for bearings to during turbine driving.

pump which supply oil to Hydraulic Control Valves (Main Valves)

oil pump for automatic emergency protection to start by a bearing oil pressure drop.

tank which holds quantity of oil necessary for a circulation system of the bearing oil.
