Consider the Rankine cycle below with steam flow rate of 5kg/s. The steam receives heat from the combustion gases in the furnace of the generator; assume the combustion gases change temperature from 2000°K to 425 K in flowing through the steam generator. The cooling water enters the condenser 20°C and leaves at 40°C. Assume the flow in the pump and the turbine is adiabatic and internally reversible. Also assume the combustion gas has the properties of air. If To is...

A combined gas-steam power plant uses a simple gas turbine for
the topping cycle and a simple Rankine cycle for the bottoming
cycle. Atmospheric air enters the compressor at 101 kPa and 20 °C,
and the maximum gas cycle temperature is 1100 °C. The
compressor pressure ratio is 8. The gas stream leaves the heat
exchanger at the saturation temperature of the steam flowing
through the heat exchanger. Steam enters the heat exchanger at a
pressure of 6 MPa and...

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a shell-and-tube heat exchanger consisting of a single shell and 30,000 tubes, each executing two passes (see figure below). The tubes are of thin wall construction with D=25mm, and steam condenses on their outer surface with an associated convection coefficient ho=11,000W/ m K The heat transfer rate that must be effected by the heat exchanger...

3-40 In the condenser of a steam power plant the steam from the turbine enters the condenser at 0.10 bar with a quality of 95 percent and leaves at the same pressure as a saturated liquid. The steam is condensed by transferring heat to a stream of cooling water which enters at 1.3 bars and 5°C and leaves the heat exchanger at 1.2 bars and 25°C·The environmental temperature is 5°C. Determine a. the change in stream availability (exergy) of the...

Flue gas from a sugar mill furnace burning bagasse fibre in air contains 8.35% CO2, 15.5% H2O, 0.55% O2 and 75.6%N2. 130 kmol/min of the flue gas exits the furnace at 1300 C and 1atm and is used to generate steam in an adiabatic boiler (i.e. well-insulated heat exchanger). After exchanging heat with the steam, the flue gas leaves the boiler at 350 C and 1atm. Saturated liquid water at 75 C enters the adiabatic boiler tubes where it is...
