A steam generator is needed in the design of new mini-power
plant. This generator can
be purchased with two different specification proposals, A or B.
Proposal A has life
of 15 years, a first cost of RM45,000 to buy with estimated an
annual saving of
RM3,500 per year and estimated for an annual operating &
maintenance cost of RM750
per year. A salvage value of RM10,700 and one-off overhaul in year
9 that cost RM
1,500. Proposal B has a life 15 years, a first cost of RM50, 000 to
buy with estimated
an annual saving of RM1,700per year and estimated for an annual
operating &
maintenance cost of RM800 per year. A salvage value of RM25, 000
and one-off
overhaul in year 12 that cost RM1, 500. Propose which specification
should be chosen
using multiple attribute present worth, PW if a firm use an
interest rate of 0.25%? Stated
the preferred proposal based on this analysis.

Superheated steam at 8 MPa and 480°C leaves the steam generator
of a vapor power plant. Heat transfer and frictional effects in the
line connecting the steam generator and the turbine reduce the
pressure and temperature at the turbine inlet to 7.7 MPa and 440°C,
respectively. The pressure at the exit of the turbine is 10 kPa,
and the turbine operates adiabatically. Liquid leaves the condenser
at 8 kPa, 36°C. The pressure is increased to 8.6 MPa across the
pump....

Design a steam power plant that works as an ideal Regenerative
Rankine cycle with 2 closed feedwater heaters cascaded backwards by
selecting their extraction pressures to optimize cycle efficiency.
The available steam conditions at the exit of the boiler are 3 MPa
and 590 °C and the condenser pressure is 20 kPa. The steam flow
rate at the inlet of the turbine is 80 kg/s. A T-s diagram for the
cycle should be provided along with a table showing the...

A proposed steam power plant design consists of an ideal Rankine
cycle with reheat and regeneration. Steam enters Turbine 1 at P1
and T1 at the rate of m1 and exits at P2. A fraction (y') of the
steam exiting Turbine 1 is diverted to an open feedwater heater
while the remainder is reheated to T3 before entering Turbine 2.
The condenser operates at P4. Saturated liquid exits the condenser
and is fed to Pump 1. The outlet of Pump...

Consider a coal-fired steam power plant that produces 175 MW of
electric power. The power plant
operates on a simple ideal Rankine cycle with turbine inlet
conditions of
7 MPa and 550°C and a condenser pressure of 15 kPa. The coal has
a
heating value (energy released when the fuel is burned) of 29,300
kJ/kg.
Assuming that 75% of this energy is transferred to the steam in the
boiler
and that the pump has an efficiency of 80% and the...

At a steam power plant, steam engines work in pairs, the heat
output of the first one being the approximate heat input of the
second. The operating temperatures of the first are 770 ∘C and 460
∘C, and of the second 435 ∘C and 280 ∘C.
A) If the heat of combustion of coal is 2.8×107J/kg, at what
rate must coal be burned if the plant is to put out 860 MW of
power? Assume the efficiency of the engines...

A steam power plant operates on a practical Rankine Cycle. The
steam enters the turbine at 3 MPa and “648” K and is condensed in
the condenser at a pressure of 46 kPa. You are assigned on a
project to improve the thermal efficiency of this plant. a) Draw
the schematic of the plant and determine the thermal efficiency of
the practical cycle assuming that the efficiencies of pump and
turbine are 0.75 and 0.7, respectively. ( b) Draw a...
