There is a two fold answer the first one is that without condensing the steam back to water you could not recycle the condensate (unable to pump steam)therefore large capacity generators could not operate as production of suitably pure water for boiler feed could not be produced
The other great advantage is that by creating a near perfect vacuum in the condenser the steam will remain a gas until around 33 deg C (approx saturation temperature at 50mb ) enabling more work to be used by the removal of more latent heat from the steam and then pumping the water at the same temperature but now under pressure of course, on its cycle back to the boiler
What else can I help you with?
What is the reason of vacuum dropping in steam turbine?
Vacuum dropping in a steam turbine can be caused by air leakage into the system, inadequate steam supply, malfunctioning condenser or cooling system, or excessive steam flow rate. This drop in vacuum can reduce the efficiency of the turbine and impact its performance. Regular monitoring and maintenance of the system are essential to prevent issues leading to vacuum drop.
How TO generate electricity from steam?
To generate electricity from steam, a steam turbine is typically used. High-pressure steam is directed onto the turbine blades, causing the turbine to spin. The spinning turbine is connected to a generator, which converts the mechanical energy into electrical energy.
What are the key components and processes depicted in a Rankine cycle diagram?
A Rankine cycle diagram typically shows four main components: a boiler, a turbine, a condenser, and a pump. The process involves the heating of water in the boiler to produce steam, which then expands through the turbine to generate power. The steam is then condensed back into water in the condenser before being pumped back to the boiler to repeat the cycle.
How do you increase the efficiency of rankine cycle?
To increase the efficiency of a Rankine cycle, you can: increase the boiler pressure to increase the temperature of the steam entering the turbine, lower the condenser pressure to improve the quality of the exhaust steam, and use regenerative feedwater heating to reduce heat losses. Additionally, using superheated steam can also improve the efficiency of the cycle.
What is the condensation point of steam?
The condensation point of steam is when it changes from a gas to a liquid at 100 degrees Celsius.
What type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
Why deaerator is placed at a higher level than turbine?
Your question is very Bad should you know the dearator in water cycle and turbine in steam cycle
What are the parts of steam turbine?
Steam turbine is a machine that extracts thermal energy from pressurized steam. It is made up of casing essential to which the blades are attached onto it and a rotor that carries the moving blades.
What is the definition of combined cycle turbine technology?
Using waste energy in a gas fired electricity generation plant to run a steam turbine
What are reasons for over speed tripping of steam turbine genarator in a combined cycle power plant?
wHAT??
What should be the possible reasons of vacuum drop of turbine?
In the low pressure side of a steam turbine, the vacuum is maintained by the condensation of steam in the condenser. At high loads, the condenser may not satisify the demand, allowing steam to remain gaseous for a longer period of time. This can cause pressure to rise.
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
What are thermal energy advantagaes?
its in a cycle. water is heated to produce steam which spins the turbine. and when steam condenses it forms water which can be evaporated again
Why extraction taken from steam turbine?
Why extractions are taken out from steam turbine.
What is the reason of vacuum dropping in steam turbine?
Vacuum dropping in a steam turbine can be caused by air leakage into the system, inadequate steam supply, malfunctioning condenser or cooling system, or excessive steam flow rate. This drop in vacuum can reduce the efficiency of the turbine and impact its performance. Regular monitoring and maintenance of the system are essential to prevent issues leading to vacuum drop.
How do you produce electricity from biogas?
You can use the bio gas to fuel either a steam cycle generator or a gas turbine.
Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
