DESIGN OF A STEAM POWER PLANT IN THE AGE OF CARBON TAXATION, Due: Aug. 15, 2018...
Please summarise below in a concise way. Alternative energy is studied as a result of the increasing costs of energy, the harm that fossil fuel may be costing the planet and the fact the energy demand is going up and the supply of fossil fuels may be going down. Energy and economic growth have always been going up, the more energy we consume, the more wealth we create as seen in the GDP of developed nations such as the USA,...
A fossil-fuel steam power plant operates at about 50% of Carnot thermal efficiency. It has been suggested that the air pollution from a plant that operates at 1000 F would contribute 1/2 the pollution (per ton of coal burned) that the present system that operates at about 1500 F. The heat rejection temperature is 70 F. For the same electrical output what is the percent difference in the pollution resulting from the combustion? Assume that the thermal energy released by...
Design of a Solar Thermal Power Plant The scheme of the solar thermal power plant is depicted in Figure 1. It features a Rankine-cycle based solar thermal power plant using tower technology. Technical data and assumptions: • = net electrical power output (turbine - pump) = 12 MW • Working fluid: water. • Condenser: outlet temperature = 320 K, outlet steam quality = 0%; no pressure drop through condenser. • Pump: adiabatic, outlet pressure = 170 bar; outlet temperature =...

A power plant taps steam superheated by geothermal energy to 421 K (the temperature of the hot reservoir) and uses the steam to do work in turning the turbine of an electric generator. The steam is then converted back into water in a condenser at 321 K (the temperature of the cold reservoir), after which the water is pumped back down into the earth where it is heated again. The output power (work per unit time) of the plant is...
Design a steam power plant of 1 MW using a rankine cycle. Describe the rankine cycle with additional modifications e.g reheat, regeneration (feedwater) to improve efficient and it's T-S diagram. In your analysis, write down state equations and consider the losses associated with each component to calculate overall thermal efficiency. Also perform a cost analysis for all the equipment for a period of 10 years.
A natural-gas-fired steam power plant produces 50 MW of net work while consuming natural gas at a rate of 500 MMBTU/hr (five- hundred million BTUs of heat emitted by the combusting natural gas per hour). (a) Determine the thermal efficiency of this facility (b) Determine the rate of heat rejection from this facility (c) If the flame temperature of the natural gas were 800°C and the heat rejected by the facility was into a nearby lake at 15°C, determine the...
Please answer Questions e-f-g-h: (a) The boiler of a power plant operates at a maximum temperature of 750oC. The condenser of the power plant draws in cooling water at 20oC. What is the theoretical maximum efficiency of the plant? (b) Now suppose that a real power plant is built to have an efficiency that is 80% of the theoretical efficiency. The power plant needs to generate 1GW (giga-watt) of power. How much energy (per second) needs to be supplied by...

4. Consumers Energy Inc (CSI) operates a coal fired power plant in Michigan, which has to come in compliance with nitrogen oxide (NOx) standards by reducing its NOx emissions to 50 tons per year from its current level of 150 tons/year. It is considering the following options to come in compliance. A) Install Selective Catalytic Reactor (SCR) on its boiler. SCR reduces NOx emissions by absorbing NOx in exhaust flue gases. SCR requires a capital investment of $600,000 in year...
