6 FAQs about [High and low pressure bypass oil station energy storage device]
What are IP/LP bypass stations?
IP/LP bypass stations are a type of bypass station that consists of the main valve with integrated cooling water injection, the cooling water control valve, the cooling system, the positioning cylinders, and the hydraulic supply unit. They provide bypass operation if the turbine is not operating and fast closing if the condenser must be protected for pressure and/or temperature reasons.
How does a high pressure bypass system work?
This bypass system permits stable operation of the boiler when the turbine trips off line or during start-up operations. Steam flowing through the high pressure bypass control valve is throttled and cooled to a temperature slightly above the HP turbine exhaust temperature, by spraying feed water at the outlet of the bypass control valve.
What is a high pressure turbine bypass system?
The high pressure turbine bypass system provides an alternate flow path at the high pressure side of the turbine, taking the steam from the turbine inlet t oh era i nl s c . This bypass system permits stable operation of the boiler when the turbine trips off line or during start-up operations.
What is a low pressure tubine bypass system?
It protects the reheater and quickly unloads the turbine without requiring boiler trip. The low pressure tubine bypass system presents a flow path around the LP turbine, taking steam from the reheater outlet and conditioning it to be fed into the condenser.
What is a high-pressure gaseous storage system?
High-pressure gaseous storage systems are designed with pressure relief devices (PRDs) in direct pneumatic connection to the pressure vessel that meet the requirements of either DOT or ASME code, or as required by the governing CGA standards.
How can a turbine bypass system improve reloading times?
In the event of a load rejection, reloading times can also be improved through the turbine bypass system. The turbine bypass system is designed to provide the quickest startup time by controlling both boiler pressure and temperature.
