What are the methods to improve Rankine cycle efficiency?

There are three ways to increase the efficiency of the simple ideal Rankine cycle.

• Decreasing the condenser pressure. The effect of lowering the condenser pressure on the Rankine cycle efficiency is illustrated on a T-s diagram on the left.
• Superheating the steam to a high temperature.
• Increasing the boiler pressure.

Which of the following contributes to Rankine cycle efficiency improvement in a steam power plant?

Thermal efficiency of Rankine cycle can be improved by increasing the mean temperature of heat addition, by using of high pressure steam. The mean temperature of heat addition can be increased by using super heat, reheat and regeneration.

Which is used to increase efficiency of steam power plant?

Solar energy is one of the most available source of renewable energy and could be used to increase the effectiveness of steam power plants.

What is Rankine efficiency of a steam power plant?

In a good steam power plant, the Rankine cycle efficiency varies from 35 to 45 \%.

Which of the following methods is more effective to improve the efficiency of the Rankine cycle used in thermal power plant?

The thermal efficiency of the Rankine cycle can also be increased by: Increasing the average temperature of the working fluid at which heat is added to the cycle. Decreasing the average temperature of the working fluid at which heat is rejected by the cycle.

How can the efficiency of Rankine cycle be improved Mcq?

The thermal efficiency of the Rankine cycle can be increased by the use of a regenerative heat exchanger. In this way, the amount of heat added at the low temperatures is reduced and the mean effective temperature of heat addition is increased, thus cycle efficiency is increased.

How can efficiency of plant be improved?

Identifying, improvising, and monitoring problems can enhance productivity and efficiency. Hence, these factors play an important role in order to find the issues and rectifying issues in your manufacturing plant.

Which one is used in boiler to improve the efficiency?

Much like the return of condensate to the boiler, recovering the heat from the boiler blowdown can increase boiler efficiency. The blowdown valve is used to remove boiler water which contains soluble and insoluble solids. It helps reduce the level of dissolved solids in the boiler water to prevent the boiler scale.

Which one of the following modifications to a Rankine cycle would upgrade enhance its efficiency so as to approach that of Carnot cycle co2 *?

Explanation: Area under P-V curve for Rankine will be more as compared to Carnot cycle. Explanation: In winters, the temperature of cooling water is low, which increases Condenser’s efficiency.

How can we improve plants?

What is preferable method to find boiler efficiency?

Basically Boiler efficiency can be tested by the following methods: 1) The Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel. 2) The Indirect Method: Where the efficiency is the difference between the losses and the energy input.

How can I increase the efficiency of the Rankine cycle?

There are three ways to increase the efficiency of the simple ideal Rankine cycle. 1. Decreasing the condenser pressure The effect of lowering the condenser pressure on the Rankine cycle efficiency is illustrated on a T-s diagram on the left.

How does steam temperature affect the thermal efficiency of Rankine cycle?

Thermal efficiency of the rankine cycle increases on account of increase in steam temperature. One desirable effect of increasing the increasing the steam temperature is that it doesn’t allow to the last stage mositure \% of steam to increase. This effect can be easily seen on the T-s diagram (Fig:2) above.

What is the difference between Rankine cycle and Carnot cycle?

Rankine cycle is nothing but a modification of Carnot cycle. Ideal Rankine cycle is very useful in steam power plants and gas power plants. To improve the efficiency of Rankine cycle in the steam power plant, there are some changes in Rankine cycle which differs from the Carnot cycle.

Does lowering the condenser pressure affect the performance of Rankine cycle?

With the help of the T-s diagram, the effect of lowering the condenser pressure on the performance of the cycle can be seen and understood. Positive Effects of Lowering the Condenser Pressure To milk the advantage of higher efficiency, the Rankine Cycle has to operate on lower condenser pressure usually below atmospheric.
