Power Generation through Steam.
A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power
The objective of this project is to demonstrate a prototype of steam power plant. In this prototype we produce electric energy using a turbine, that rotate using a stream of steam produced by heated water and this produce electricity further used for house hold appliances.
All steam power systems are To improve the operation and efficiency of these systems a number of other
components are added which include reheaters, additional turbines, open feedwater
heaters, and closed feedwater heaters. During the tour of the T.B. Simon Power Plant
at MSU, the student will note the power plant layout and operating conditions. With
this information, the student will use the software package RANKINE V3.0 to model
the power plant and investigate additional optimization of operating conditions. A
copy of the RANKINE V3.0 Users Guide is included with this handout. The program
itself is available on the Heat Transfer Lab computers.
The objective of this laboratory is to offer students hands-on experience with the operation of
a functional steam turbine power plant. A comparison of real world operating characteristics
to that of the ideal Rankine power cycle will be made.
The apparatus is scaled for educational use and utilizes components and systems similar to
full-scale industrial facilities. Students will be able to operate and analyze this system in
detail, allowing them to determine the efficiency of the facility and suggest possible
modifications for further improvement. The turnkey laboratory system carries the trade name
of RankineCycler™.
Fluid mechanics is concerned with the behavior of liquids and gases at rest and in motion. The
RankineCycler™ applies two main topics of fluid mechanics: viscous pipe flow and turbo?machinery.
Viscous pipe flow will either be completely filled or it will be partially filled open channel. It should
be assumed that the steam moving through the pipe is completely filling the pipe. Determining
how the flow is moving through the pipe is also important. Laminar, transitional, and turbulent flow
could show up each of these cases has a different governing set of equations.
Q =V * A Equation 8
If the cross-sectional area, A, and the velocity, V, is known the volumetric flow rate, Q, can be
found. It is also essential to find the Reynolds Number
µ
?VD Re = Equation 9
Where: r, is the density of the working fluid, V, is the average velocity in the pipe, D, is the pipe
diameter, and m, and is the dynamic viscosity of the fluid. The Reynolds Number will help
determine the type of flow. If the Reynolds Number in a round pipe is less than ~ 2100 the flow is
laminar. If the Reynolds Number is greater than 4000 in a round pipe is determined to be
turbulent. The transition region is between Reynolds Numbers of 2100 and 4000, respectively.
When a fluid enters a pipe with a near uniform velocity profile viscous effects cause the
fluid to stick to the pipe wall. A boundary will form so the velocity profile changes with distance
from the entrance region till the end of the entrance region, the boundary layer has completely
filled the pipe. The entrance length is defined for laminar and turbulent flows as:
= 0.06

After the entrance region fully developed flow might be obtained depending upon the length of the
pipe.
The pressure difference across a section of pipe:
?p = p1 ? p2 Equation 12
This is the force that moves the fluid through the pipe.
Fully developed laminar horizontal pipe flow can be described as the difference in
pressure acting on the end of the pipe and the shear stress acting on the walls of the pipe. Thus:
