However, above about 650oC various forms of metal fatigue become significant due to very high temperatures and pressures that the walls of the boiler tubes have to withstand. • A typical 500 MW coal-fired plant consumes around 250 tonnes of coal an hour. Efficiency of Thermal Power Plant • The efficiency of a Rankine cycle is usually limited by the working fluid. Without the pressure reaching super critical levels for the working fluid, the temperature range the cycle can operate over is quite small: turbine entry temperatures are typically 565°C (the creep limit of stainless steel) and condenser temperatures are around 30°C. This gives a theoretical Carnot efficiency of about 63% compared with an actual efficiency of 42% for a modern coal-fired power station. • The power output or capacity...

A generating system has two basic components, a turbine, which produces rotary motion and a generator, which convert s the rotational energy into electrical energy. A generator has ‘rotor’ which is rotated by a turbine and a ‘stator’ which has the sets of coils in which electricity is generated when the rotor rotates. The difference between various modes of production lies in the techniques used to generate steam, which in turn will rotate the turbine. Based on various modes of rotating the turbine, we can classify the modes of power generation in broadly four categories 1. Hydro Power Plant 2. Thermal Power Plant 3. Nuclear Power Plant 4.

...Quarterly of the Royal Academy of Engineering Ingenia 18, February/March 2004 Concentrating solar power A review of the technology Is solar power the answer to the ever-growing problems of global warming and depleting fossil fuel supplies? In the first of two articles Hans Müller-Steinhagen and Franz Trieb explain the principles and development of concentrated solar-thermal power and outline its considerable potential for alleviating the constant pressure on our existing resources. Three main technologies have been identified during the past decades for generating electricity in the 10 kW to several 1000 MW range: ● he limited supply of fossil hydrocarbon resources and the negative impact of CO2 emissions on the global environment dictate the increasing usage of renewable energy sources. Concentrated solar power (CSP) is the most likely candidate for providing the majority of this renewable energy, because it is amongst the most cost-effective renewable electricity technologies and because its supply is not restricted if the energy generated is transported from the world's solar belt to the population centres. T dish/engine technology, which can directly generate electricity in isolated locations parabolic and Fresnel trough technology, which produces high pressure superheated steam solar tower technology, which produces air above 1000°C or synthesis gas for gas turbine operation. ● ● While these technologies have reached a certain maturity, as has been demonstrated...

As biofuels are renewable, abundant and has domestic usage, the sources of biofuels can help the world reduce its dependence on petroleum products and natural gas. Biofuels can be converted into liquid, solid and gaseous fuels with the help of some physical, chemical and biological conversion processes. The conversion of biofuel material has a precise objective to transform a carbonaceous solid material, which is originally difficult to handle, bulky and of low energy concentration, into fuels having physico-chemical characteristics that permit economic storage and transferability through pumping systems. The use of biofuel products provides substantial benefits as far as the environment is concerned. A simulation study has been carried out to arrive at the power output under limiting conditions as well as perform changes in the fuel gas system for the augmentation. The simulation study...

...Electricity: What Powers Our Planet To Whom It May Concern: It’s dark and you are trying to sign paperwork. You want to turn on the lights so you can see better. With one flick, the whole room illuminates. But, congressman, let me ask you. Have you ever wondered how electricity works? What is it that makes electricity possible? What did it take for light to have the ability to stream out of the light bulb? We take electricity for granted, but not many of us actually look into it. People often do not know how electricity is the way it is, but instead they see electricity as something that is very accessible and plentiful. So, congressman, you have the money, and I have the brains. You want to know how to spend the 200 billion? I’ll tell you. Let’s start off with what electricity really is. You hear that word so many times in your daily life, but few have heard the scientific definition. Electricity is a type of energy produced from the existence of electrons or protons, either statically as a build-up of charge, or dynamically as a current. It is usually categorized into two different currents: alternating current (AC) and direct current (DC). Alternating current is a constant flow of electric charge that reverses its course from time to time. Direct current is the opposite; it only runs in one direction. Within those two currents are things such as volts, watts, amperes (or amps), and ohms. Volts are the SI unit of electromotive force, the distinction of potential that would...

...proven solar thermal electric technology. This is primarily due to nine large commercial-scale solar power plants, the first of which has been operating in the California Mojave Desert since 1984. These plants, which continue to operate on a daily basis, range in size from 14 to 80 MW and represent a total of 354 MW of installed electric generating capacity. Large fields of parabolic trough collectors supply the thermal energy used to produce steam for a Rankine steam turbine/generator cycle. Figure 1. Solar/Rankine parabolic trough system schematic [1]. Plant Overview Figure 1 shows a process flow diagram that is representative of the majority of parabolic trough solar power plants in operation today. The collector field consists of a large field of single-axis tracking parabolic trough solar collectors. The solar field is modular in nature and is composed of many parallel rows of solar collectors aligned on a north-south horizontal axis. Each solar collector has a linear parabolic-shaped reflector that focuses the sun’s direct beam radiation on a linear receiver located at the focus of the parabola. The collectors track the sun from east to west during the day to ensure that the sun is continuously focused on the linear receiver. A heat transfer fluid (HTF) is heated as it circulates through the receiver and returns to a series of heat exchangers in the power block where the fluid is used to 5-24 SOLAR PARABOLIC TROUGH generate high-pressure superheated steam.

...EMM 516 course (power plant engineering) we under took several field trips to relate what has been taught in class and how the power generation objective is achieved out there. This report is to be submitted in partial fulfillment of the mentioned course. | Introduction Kenya’s energy sector faces daunting challenges, characterized by high cost and insufficient supply. Nearly 80% of Kenyans are living without access to basic Energy services; a top priority for the government is to improve access to adequate and affordable energy supply. The existing energy supply is heavily dependent upon hydroelectric power thus due to the rapid growth in demand for energy means that Kenya must find new ways to provide crucial energy services to its people. The available options include Renewable energy resources like geothermal. Kenya has nearly 7,000 MW geothermal potential, yet it remains largely undeveloped due to economic and financial limitations, insufficient technical and human capacity, and various social constraints. However the government has now turned around and is aiming at producing about 16000MW of power by 2030. The country currently produces about 1500 MWs primarily from hydro stations (57%-hydro power, about 32%-thermal and the rest comprises geothermal and emergency thermal power). To bridge this huge deficit in the short time, courses as EMM 516 were developed to provide man-power needed to sustain the projected growth. First we visited the Kiambere power station the Tana...
