In the Rankine cycle, increasing the pressure raises the boiling point of the working fluid, allowing it to absorb more heat during the heating phase and improve the cycle's efficiency. Higher temperatures lead to greater thermal energy conversion into work, enhancing overall efficiency as well. Conversely, lower pressure and temperature can reduce the cycle's efficiency and output power. Thus, optimizing these parameters is crucial for maximizing the performance of a Rankine cycle system.
What else can I help you with?
Why are you using condenser in rankine cycle?
The condenser is used to lower the temperature of the working fluid. This lowers the pressure and condensates any left over steam, from the turbine, so it will be purely liquid before entering the pump.
What effect does water have in the moss life cycle?
what effect does water have in the moss lifecycle
Is there a wind cycle?
Yes, there is a wind cycle known as atmospheric circulation. This involves the movement of air around the Earth driven by temperature differences, the Coriolis effect, and pressure gradients. It creates global wind patterns such as the trade winds, westerlies, and polar easterlies.
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.
How does erosion effect the rock cycle?
erosion can effect the rock cycle by turning igneouse and metamorphic rocks into sediments and eventualy turn into a sedimentary rock such as sandstone
Difference between rankine and brayton cycle?
Brayton cycle: It is open cycle. Rankine cycle: It's close cycle. Brayton cycle: Mostly used in gas turbine engine. Rankine cycle: Mostly used in power generation plant. Brayton cycle: Resemble less to Carnot cycle. Rankine cycle: Resemble is more to Carnot 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 type of cycle used in steam turbine?
Rankine cycle is used in steam turbine
What is rankin cycle?
The Rankine cycle is the fundamental thermodynamic underpinning of the Steam_engine. It is named after William_John_Macquorn_Rankine
What are the relative advantage of Rankine Cycle over Carnot Cycle in thermal power plants?
Rankine cycle allows for practical implementation with real working fluids such as water, making it more feasible for thermal power plants compared to the idealized Carnot cycle. Rankine cycle also allows for the use of turbines and pumps which are more efficient than isothermal expansion and compression processes in the Carnot cycle. Additionally, Rankine cycle can be modified with reheating and regeneration to improve efficiency further, something the Carnot cycle cannot achieve.
Why are you using condenser in rankine cycle?
The condenser is used to lower the temperature of the working fluid. This lowers the pressure and condensates any left over steam, from the turbine, so it will be purely liquid before entering the pump.
What is the difference between the Carnot cycle and the Rankine Cycle?
carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid rankine cycle is a practical cycle but with a very low efficiency so the main difference lies in the adding and rejecting of heat
How to increase a Thermal efficiency of rankine cycle?
To increase the thermal efficiency of a Rankine cycle, you can: Increase the temperature of the heat source entering the boiler. Lower the temperature of the heat sink exiting the condenser. Improve the insulation of the system to reduce heat losses. Enhance the performance of the turbine and pump by reducing internal losses.
What are four major components of the Rankine cycle?
The four major components of the rankine cycle are as follows: 1. boiler 2. turbine 3. condenser 4. pump i.e. in short (B-T-C-P)
What is modified rankine cycle?
modified rankine cycle basically same as rankine cycle but main difference is inisentropic expansion process.we are nt expanding the styeam completely.steam is expanded up to certain level and after that it dumped in condenser due to high vacuum in condenser.the work losses by restricting the expansion of steam is very less which can be neglected.so that the stroke length of cylinder is reduced and the capitalcost of engine also reduced.engine performance is also good
Why you use condensor in the steam power plant?
The steam exiting the low pressure end of the turbine has to be condensed back to water in order to be pumped back at high pressure to the inlet of the steam raising units. The cycle is called the Rankine cycle and is common to all steam type power plants whether fossil fired or nuclear.
What is super critical technology?
»The supercritical technology is nothing but the thermodynamic where there is no clear distinction between the Water and Steam phase in the Rankine Cycle•Water reaches to steam state at a critical pressure above 22.1 Mpa.
