Fuel Stack Combustion gases to stack Boiler AirD Turbine Electric generator Condenser Warm water Feedwater pump Pump Makeup water Cooling tower Cooled water A chemical plant currently purchases 2.4 x 105 MW.h of electricity annually from the local utility provider. 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.

In an ideal open feedwater heater Rankine cycle, water leaves the condenser at 100 kPa and from the boiler at 500 *C and 3 MPa pressure. The water emerges as a saturated liquid at 400 kPa pressure from the open feed water shown in the figure. According to this; a) Show the cycle in a T-s diagram with saturated liquid and saturated vapor curves. b) Find the total pump work (kJ/kg). c) Find the ratio (y) of the mass of steam leaving to heat the turbine feedwater to the mass of steam entering the high pressure turbine.

Q1) How to steam flow control in thermal power plants?

Recommend general considerations when selecting a site for Thermoelectric Power Plant.
A power plant using a Rankine power generation cycle and steam operates at a temperature of 81.25°C in the condenser, a pressure of 5 MPa in the boiler and a maximum boiler temp of 775°C. The cycle operates at steady state with a mass flow rate of 2.5kg/s. Use the steam tables in the appendix of Sandler (p. 917 to 925). a.) Draw out the cycle, calculate the work required for the pump, the work output by the turbine, the heat into the boiler, and the heat out of the condenser. b.) What is the efficiency of this power plant? c.) If the turbine was only 89% efficient but still adiabatic (only generates 89% of the calculated work from part b), what is the overall efficiency of the cycle?
