Why do we reheat steam?
Why Reheating of steam is used.
Explanation: Work output = work done by turbine – work done by compressor.
Explanation: Since work output increases the steam rate decreases.
Explanation: Efficiency = work output / heat supplied, heat supplied is less in this condition only..
Do Stirling engines explode?
Stirling engines will explode at 250.0C. … In other words, the stirling engine continues to run quite a while after the instant the flame gauge empties and there is no more fuel in the slot to burn (unlike Vanilla machines). Prior to Buildcraft 3.2. 0, Stirling Engines were known as Steam Engines.
Are Stirling engines practical?
Applications of the Stirling engine range from mechanical propulsion to heating and cooling to electrical generation systems. … For example, a Free Piston Stirling Cooler (FPSC) can convert an electrical energy input into a practical heat pump effect, used for high-efficiency portable refrigerators and freezers.
Which type of compressor is used in a gas turbine plant?
centrifugal compressorsCompressor. Early gas turbines employed centrifugal compressors, which are relatively simple and inexpensive. They are, however, limited to low pressure ratios and cannot match the efficiencies of modern axial-flow compressors. Accordingly, centrifugal compressors are used today primarily in small industrial units.
What is the use of re heater in a gas turbine?
In gas turbine, what is the function of Re-heater? Explanation: In order to make a thermodynamic process of larger efficiency, it is shifted towards isothermal behavior.
Can a Stirling engine power a home?
The Microgen Stirling engine produces alternating current (50 Hz) and provides 1 kW of electrical power; ideal for use in domestic homes.
Which one is disadvantages of regenerator type heat exchanger?
The major disadvantage of a regenerator is that there is always some mixing of the fluid streams, and they can not be completely separated. There is an unavoidable carryover of a small fraction of one fluid stream into the other.
Which is a regenerative furnace?
A furnace in which hot gases, usually waste combustion gases, pass through a set of chambers containing firebrick structures, to which the sensible heat is given up.
What is difference between condenser and heat exchanger?
While a heat exchanger can regulate process temperatures independently, a condenser is a component of a chiller system (water-cooled or air-cooled) which functions to remove heat generated by an industrial or commercial process.
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 does regenerator mean?
1 : one that regenerates. 2 : a device used especially with hot-air engines or gas furnaces in which incoming air or gas is heated by contact with masses (as of brick) previously heated by outgoing hot air or gas.
What is regenerator in Stirling engine?
The regenerator in a Stirling engine is an internal heat exchanger for transferring heat between a working fluid and a flow-channel wall (which is also part of the regenerator). The fluid can be helium or another gas that has suitable thermodynamic properties and that does not react chemically with engine components.
How much power can a Stirling engine produce?
It has an overall efficiency of about 90%, thermal power 4.5–10.5 kW and electrical power 1.5–3 kW.
What are the two types of heat exchangers?
Types of Heat ExchangersShell and tube heat exchangers.Double pipe heat exchangers.Plate heat exchangers.Condensers, evaporators, and boilers.
What is ideal regenerative cycle?
This section will introduce one such cycle – the ideal regenerative Rankine cycle, which increases the fluid average temperature during the heat addition process. … 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 the basic principle of regeneration?
1. 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.
Which Stirling engine is the most powerful?
One of the most efficient Stirling engines ever made was the MOD II automotive engine, produced in the 1980′s. It reached a peak thermal efficiency of 38.5%. Compare this to a modern spark-ignition (gasoline) engine, which has a peak efficiency of 20-25%.
Is regeneration a hidden ability?

What is recuperator & regenerators?
Regenerators and recuperators are heat exchange systems that recover heat by cycling through heat sinks (regenerators) or through a high temperature metallic heat exchanger (recuperators). II Applications. The heat recovered by a regenerator or recuperator is most commonly used to preheat combustion air to a furnace.
Why Stirling engines are not used?
Here’s the Short Answer: Stirling engines are not good for applications that need to change their power output levels quickly, like cars for example. … Plus, they tend to be heavier (and more expensive) than gasoline or diesel engines of a similar power output.
Is parallel flow or counterflow more effective?
The exchanger is performing at its best when the outlet temperatures are equal. Counter flow heat exchangers are inherently more efficient than parallel flow heat exchangers because they create a more uniform temperature difference between the fluids, over the entire length of the fluid path.
