A medium size power station is used to produce 30 MW net power for a refinery. The station uses steam as the operating fluid and operates according to the Carnot cycle between the pressure limits of 0.4 bar and 35 bar. Steam enters the boiler as a saturated liquid and leaves it as a dry saturated vapour. (x) State the name of the cycle that is used in practice in power stations, along with three key benefits over the Carnot cycle.

An aging boiler in the local provider's facility provides 4 x 108 kg of process steam at 20 bar. Consider the feasibility of a new system to meet the need of the steam and electricity. This system will use turbine to produce the electricity and a heat- recovery steam generator to produce the steam. Write a technical proposal for your proposed system.
A power cycle operates between two thermal reservoirs at 300 K and 800 K. The working fluid of the cycle is air, which can be considered to be an ideal gas. Specific heats are not assumed to be constant. An inventor claims that for a heat input of 250 kJ, the net work from the cycle is 80 kJ. The work generating component in the cycle is a reversible, steady state turbine. The inlet pressure and temperature are 1000 kPa and 600 K and the exit temperature is 550 K. The turbine receives 150 kJ/kg of heat from the high temperature reservoir and loses 10 kJ/kg of heat to the ambient at 298 K.

In a steady-state operating power plant, saturated liquid H2O at 122 deg C is fed to a boiler at 3.756 m/s through a pipe (0.03 m diameter). It leaves the boiler at 9 bar and 88.7 m/s. Then, it enters the turbine through a constant 0.13 m diameter pipe. The exit pipe of the turbine is 0.3 m in diameter and T = 310ºC while P = 1.37 bar. If 2.5 kg/s water is fed and there is change in KE, prove that the fluid enters the turbine at 637.06 deg C.
