Quick Answer: What Is The Basic Principle Of Regeneration?

What is the mean temperature of heat addition what is its effect on cycle efficiency?

4.

What is the effect of the increase in the superheat at constant pressure.

Explanation: As there is an increase in superheat at constant pressure, the cycle efficiency increases & hence there is an increase in the mean temperature of heat addition..

What is specific steam rate?

Specific Steam Consumption is defined as the steam consumed by a locomotive’s cylinders per unit output of power. It is typically measured in kg/kWh or kg/KJ.

Which of the following has highest operating cost?

Which of the following have highest operating cost? Explanation: Operating cost of hydroelectric and Solar Power Plant are very low because they don’t need fuel. In nuclear power plant fuel required is of very small quantity as compared to coal required by thermal power plant.

What is a blastema mean?

Regeneration BudBlastema, also called Regeneration Bud, in zoology, a mass of undifferentiated cells that has the capability to develop into an organ or an appendage. In lower vertebrates the blastema is particularly important in the regeneration of severed limbs.

What are the types of regeneration?

Types of regeneration : Regeneration is of two main type – Reparative and Restorative. (1) Reparative regeneration : In this, multicellular organism has the power only to repair certain damaged cells of the body. It is a common phenomenon observed in both invertebrates as well as the vertebrates.

What is the function of regenerator Mcq?

What is the function of regenerator? Explanation: Regenerator is usually of shell and tube construction. Regenerator uses the heat of exhaust gas to heat compressed air before it is sent to combustion chamber. This reduces the fuel consumption and improves the cycle thermal efficiency.

What is the effect of increase in regeneration on steam rate?

Explanation: Increase in steam rate increases by regeneration, i.e., more steam has to circulate per hour to produce unit shaft output. Hence, it increases boiler size.

What is an example of regeneration?

Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method of budding. … Echinoderms (such as the sea star), crayfish, many reptiles, and amphibians exhibit remarkable examples of tissue regeneration.

What is the function of regenerator?

As an exhaust-gas heat exchanger, a regenerator recovers heat from the exhaust and uses it to preheat the compressed air before the compressed air enters the combustor. Preheating of the compressed air permits a small heat input to the combustor for a given power output of the engine.

What is the air standard cycle for a gas turbine called?

Joule cycle5 Joule (or Brayton) Cycle. The Joule cycle is the air-standard cycle which describes the processes in the gas turbine. The Joule cycle has constant pressure combustion and constant pressure heat rejection.

What is the efficiency of Rankine Cycle?

Thermal efficiency of a practical Rankine cycle, The performance of an actual turbine or pump is usually expressed in terms of isentropic efficiency. Isentropic efficiency of turbine (hT) is defined as the ratio of Work delivered by actual turbine to Work delivered by an isentropic turbine .

What type of process is the ideal Rankine Cycle?

The Rankine cycle is the ideal cycle for vapor power plants; it includes the following four reversible processes: 1-2: Isentropic compression Water enters the pump as state 1 as saturated liquid and is compressed isentropically to the operating pressure of the boiler.

What is meant by the term regeneration?

1 : an act or the process of regenerating : the state of being regenerated. 2 : spiritual renewal or revival. 3 : renewal or restoration of a body, bodily part, or biological system (such as a forest) after injury or as a normal process.

What is regeneration and its types?

Regeneration is one of the processes in which if an organism is cut into several pieces, each of its parts regrows to the original state. This process is carried out by specialized cells called stem cells. … Each cell undergoes changes to form various cell types and tissues.

What is power plant regeneration?

To save fuel, efforts are constantly made to improve the efficiency of the cycle on which steam power plants operate. … This process is called regeneration and the heat exchanger where heat is transferred from steam to feedwater is called a regenerator, or a feedwater heater.

What is a regenerative cycle?

: a cycle in a steam engine using heat that would ordinarily be lost: such as. a : a multiple-expansion steam-engine cycle in which the receivers are used as successive feed-water heaters.

What animals can grow back limbs?

Axolotl. The axolotl (say “ax-oh-lot-el”), a Mexican species of salamander also known as a Mexican walking fish, is able to regenerate, repair or replace its arms, legs, tail, lower jaw, brain and heart!

Why both reheating and regeneration is used together?

Explanation: When vaporization pressure is high, the reheating of steam is adopted. 2. Why both reheating and regeneration is used together? Explanation: Thus a modern steam power plant has both reheating and regeneration.
