What is meant by regeneration in power plant?
Regeneration or recouperation uses a heat exchanger in which exhaust heat is recovered to preheat the compressed inlet air prior to the combustion chamber as shown in Figure 16-9. The increased combustion air temperature reduces the fuel requirement to maintain power turbine inlet temperatures.
What is regeneration in turbine?
Regenerative is a thermal process that utilizes the remaining heat energy of the exhaust gases leaving the gas turbine. This can be done by exchanging the heat between the exhaust hot gases exit from gas turbine with the compressed air exit from the compressor utilizing shell and tube heat exchanger [1] [2] .
What is regeneration and reheating?
Reheating of steam improved the thermal efficiency of the plant, net work output of turbine, reduction in blade erosion (or quality of steam improve). By regeneration thermal efficiency of the plant can be increased but it does not affect work output from turbine.
What is regenerative cycle in thermal power plant?
: 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 is the principle of regeneration?
What is the basic principle of regeneration? Explanation: In regeneration steam from condenser is circulated through turbine to increase steam temperature before it enters boiler. Explanation: Feedwater is preheated so as to decrease the fuel consumption which increases efficiency.
What is the basic principles of regeneration?
What is the necessity of regeneration in power plant?
Regeneration improves the cycle efficiency by increasing the initial feed water temperature before the water, water enters the boiler and also helps in controlling the large the large flow rate of steam at the turbine exhaust.
What is ideal regenerative cycle?
In an ideal regenerative Rankine cycle, steam enters the turbine at the boiler pressure and expands isentropically to an intermediate pressure. Some steam is extracted at this state and routed to the feedwater heater, while the remaining steam continues to expand isentropically to the condenser pressure.
What is regeneration in power plant engineering Mcq?
Explanation: In the process of regeneration, energy is exchanged internally between the expanding fluid in the turbine & the compressed fluid before heat addition. Explanation: Here heaters are assumed to be adequately insulated, & there is no heat gain from or heat loss to, the surrounding.
What is plant regeneration?
Plant regeneration refers to the physiological renewal, repair, or replacement of tissue in plants.
What is the regenerative system in a power plant?
The regenerative system in a utility power plant is the go-between that allows operation of the turbine and boiler as a single unit. The major control loops of this system are discussed in the following [5].
Is there any direct way to regenerate a plant?
Widespread success using different culture conditions has since led to the production of a large variety of plant tissues and much information regarding plant regeneration. Regeneration can involve direct or indirect organogenesis ( Hicks, 1980 ).
What happens when you add regeneration to the gas turbine cycle?
It was found that adding regeneration to the simple gas turbine cycle results in an increase in the thermal efficiency of cycle. It was also found that including regeneration in gas turbine cycle results in an increase in the output power of the cycle, and it results in a decrease in the exhaust gas temperature.
How is plant regeneration used in micropropagation?
Types of plant regeneration system used in micropropagation. Plant regeneration involves the in vitro culture of cells, tissues, and organs under defined physical and chemical conditions. Critical for in vitro plant propagation and biotechnology, this phenomenon is also applicable to studies of plant developmental regulatory mechanisms.
