The efficiency of power plant based on the Rankine Cycle can be calculated from the Temperature-Entropy (Ts) Diagram.
Area on the Ts Diagram represents energy. The efficiency of the cycle can be calculated by dividing WorkOut (the area enclosed by the cycle) by HeatAdded. Note that HeatAdded - WorkOut = HeatRejected.
Increasing the steam temperature and pressure improves the ratio of these areas.
Where the pressure is increased to above the Critical Point, the steam plant is described as Super Critical.
Increasing the degrees of superheat in the steam also reduces the wetness of the steam in the last row of blades in the turbine.
What else can I help you with?
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.
The business cycle is measured by the?
production and number of people employed
What is a Binary Vapour Cycle?
A binary vapour cycle is a representation of a mercury cycle and a steam cycle on a same scale.In this vapour cycle there is comparison between the mercury cycle and steam cycle. In mercury cycle there occurs isothermal expansion of saturated water from boiler into dry saturated steam followed by isentropic expansion followed by condensation of steam and at last heating of steam and thus mercury has completed the cycle in 4 way process. In steam cycle first ther is isothermal expansion which results in converting of saturated water into dry saturated steam followed by superheated process where the steam is superheated followed by isentropic expansion of superheated steam followed by condensation of exhaust steam and at last heating of steam thus completing the cycle.
Why dual combustion cycle is called as limited pressure cycle?
In dual combustion cycle heat is added at constant volume which increases the efficiency of cycle, whereas heat addition at constant pressure limits the maximum pressure of the cycle.
Why not super heated steam used in nuclear power plant?
Superheated steam is not used in nuclear power plants because it can cause corrosion in the turbines. Additionally, using saturated steam allows for better control over the temperature and pressure in the system, enhancing safety and efficiency. Nuclear power plants typically operate with saturated steam to avoid these issues.
Which is constant pressure cycle?
diesel cycle is not called constant pressure cycle constant pressure cycle is Brayton cycle and there is hell of a difference with diesel cycle. you surely misunderstood the question man
When do auroras occur most frequently?
Auroras occur most frequently during the mostintense phase of the 11-year sunspot cycle.
What are the two methods employed for lubricating 4 cycle engines?
splash system and pump system
The maximum arterial pressure during each cardiac cycle is the?
systolic pressure
What is the purpose of heat and pressure in the water cycle?
Heat and pressure help in changing the state of matter. Water exists in different state in water cycle.
What is a brief description of the basic refrigeration cycle?
Starting at the compressor;Low pressure vapor refrigerant is compressed and discharged out of the compressor.The refrigerant at this point is a high temperature, high pressure, superheated vapor.The high pressure refrigerant flows to the condenser by way of the "Discharge Line".The condenser changes the high pressure refrigerant from a high temperature vapor to a low temperature liquid and leaves through the "Liquid Line".The high pressure refrigerant then flows through a filter dryer to the Thermal Expansion valve or TXV.The TXV meters the correct amount of liquid refrigerant into the evaporator.As the TXV meters the refrigerant, the high pressure liquid changes to a low pressure, low temperature, saturated vapor.This saturated vapor enters the evaporator and is changed to a low pressure dry vapor.The low pressure dry vapor is then returned to the compressor in the "Suction line".The cycle then starts over.
What is pressure cycle?
Pressure cycle refers to the fluctuation of pressure within a system over a period of time. It typically involves a repetitive variation in pressure levels, such as in a compressor or pump operation. Pressure cycles are important to consider in engineering applications to ensure proper functioning and efficiency of systems.
