Thermal power plants : advanced applications( Book )

1 edition published in 2013 in English and held by 3 WorldCat member libraries worldwide

Thermal power plants are one of the most important process industries for engineering professionals. Over the past few decades, the power sector has been facing a number of critical issues. However, the most fundamental challenge is meeting the growing power demand in sustainable and efficient ways. Practicing power plant engineers not only look after operation and maintenance of the plant, but also look after a range of activities, including research and development, starting from power generation, to environmental assessment of power plants. The book Thermal Power Plants covers features, operational issues, advantages, and limitations of power plants, as well as benefits of renewable power generation. It also introduces thermal performance analysis, fuel combustion issues, performance monitoring and modelling, plants health monitoring, including component fault diagnosis and prognosis, functional analysis, economics of plant operation and maintenance, and environmental aspects. This book addresses several issues related to both coal fired and gas turbine power plants. The book is suitable for both undergraduate and research for higher degree students, and of course, for practicing power plant engineers

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

The study investigates the technologies that have the potential to provide feasible reduction of carbon dioxide (CO2) from a reference power plant. Particular focus has been given to mineral carbonation (at 1 bar) in which magnesium (Mg) and/or calcium (Ca) bearing materials fixate themselves to CO2 molecules to produce Mg and/or Ca carbonates in a solid stable form. The study also involved energy and mass balances of various mineral carbonation systems for simulation in Simulink. Furthermore, the various carbonation systems were incorporated into a model of a reference plants operating efficiency. This allowed for analysis of the impact that the carbonation systems would have on the existing plants performance
Towards energy efficient building assets : review on sub-tropical climate by Ashfaque Ahmed Chowdhury( )

1 edition published in 2006 in Undetermined and held by 1 WorldCat member library worldwide

The energy efficient building asset is the key to the buildings sustainability. To approach the concept of energy efficient building assets in a sub-tropical climate, building assets must adopt a number of innovative strategies to take advantage of subtropical climate. A framework for understanding the climate comfort building relationship was proposed (Olgyay, 1953). This understanding was adapted to the psychrometric chart and was further developed to produce 'building bioclimatic chart' (Givoni, 1969). Milne (1979) elaborated these further and developed boundaries for outdoor conditions in terms of temperature and humidity which could be made comfortable by various energy conservation and management techniques. The importance of energy efficiency improvement in building asset is elaborated. Appropriate energy efficient technologies for building systems particularly Heating, Ventilation and Air Conditioning systems (HVAC) for subtropical/ warm humid climates is presented. The effectiveness of climate-responsive building design and space-conditioning strategies within the building assets in sub-tropical Queensland, Australia is reviewed and discussed

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

The characteristics of moulds in subtropical Central Queensland University (CQU) Rockhampton campus buildings are analysed. The fungal spore concentrations indoors and outdoors are compared and correlations between fungal spore concentrations and environmental parameters such as temperature and humidity are developed. Specific genera of moulds and total spores were identified and recovered colonies were counted from the airborne samples. The SPSS (Statistical Product and Service Solutions) software was used for nonparametric data analysis. Subtropical Central Queensland (Rockhampton) region has two main seasons: wet (December-March) and dry (May-October). Total airborne fungal spore concentrations were found highest in the dry season and lowest in the wet season and were positively correlated with relative humidity and temperature
A numerical model of an electrostatic precipitator by Shah Haque( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

This paper presents a Computational Fluid Dynamics (CFD) model for a wire-plate electrostatic precipitator (ESP). The turbulent gas flow and the particle motion under electrostatic forces are modelled using the CFD code FLUENT. Numerical calculations for the gas flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modelled using the k-Sf turbulence model. An additional source term is added to the gas flow equation to capture the effect of electric field. This additional source term is obtained by solving a coupled system of the electric field and charge transport equations. The particle phase is simulated by using Discrete Phase Model (DPM). The results of the simulation are presented showing the particle trajectory inside the ESP under the influence of both aerodynamic and electrostatic forces. The simulated results have been validated by the established data. The model developed is useful to gain insight into the particle collection phenomena that takes place inside an industrial ESP

Environmental and economic analysis for grid-connected hybrid photovoltaic-wind power system in a hot arid environment by Gang Liu( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

This paper deals with the environmental and economic benefits of hybrid renewable energy (HRE) system in a hot arid environment. This paper focuses on small-scale operations of 100kWh per day energy generation of HRE system as grid-assisted power generation in conjunction with solar (photovoltaic) and wind energy components. A comparison is drawn between a grid-connected HRE system operation and a standard grid operation in focusing on environmental and economic impacts. Emissions and the renewable energy generation fraction (RF) of total energy consumption are calculated as the main environmental indicator. Costs including net present cost (NPC) and cost of energy (COE) are calculated for economic evaluation. To simulate long-term continuous implementation of the HRE system, the hourly mean global solar radiation and wind speed data of 2007, from Alice Spring (23.70°S,133.88°E) of Australia, are used as an example of a typical hot arid climate. The HRE system is implemented at a monthly solar exposure between 13.31 and 21.3 (MJ/m^2)/day and mean wind speed of 7.0 ms. The Micropower Optimization Model software HOMER by the National Renewable Energy Laboratory is used. It is found, for Alice Springs arid climates, the optimum results of HRE system show a 64.4% reduction of emissions including CO_2, NO_x and SO_2. The optimum renewable fraction (RF) is 58%. It also has benefits of cost saving. The reduced COE is only equal to about 81.7% of energy consumption from standard grid. In addition, through a set of sensitivity analysis, it is also found that the wind speed has more effects on the environmental and economic performance of a HRE system under the specific climate

Implementing renewable energy for HVAC systems in entertainment and exhibition centres by Ali Baniyounes( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

Entertainment and exhibition centers are unlike any other commercial property since they have a special energy needs. High heat and electricity loads are the main key elements to face by the design engineers. By implementing renewable energy for heating, ventilating and air conditioning (HVAC) in entertainment and exhibition centers, a significant amount of energy savings can be achieved and this will also contribute in reducing gas emission. All power plants generating the electricity today produce gases and waste that have a negative impact on the environment. During the summer the demand for electricity increases dramatically because of the extensive use of HVAC systems, this increases the peak electric load, causing major problems in the national electric supply system. Acknowledging that global warming is the number one environmental threat, because of gas emission, puts a serious pressure on mankind to reduce carbon dioxide (CO2) emission to the atmosphere. High fuel prices force decision makers to adopt and encourage renewable energy resources. Implementing renewable energy might be a way to reduce the demand for electricity. In addition, most renewable energy systems are being developed in ways that reduce the need for convention fuel. This study presents a thorough review on zero emissions technologies for the built environment. The specific attention is given for subtropical climate in Australia. Both technical and economic feasibility compared to only grid connected HVAC are also discussed. This study contributes to the understanding and process development for implementing solar assisted HVAC systems in buildings in subtropical climates

Macadamia Biodiesel as a Sustainable and Alternative Transport Fuel in Australia( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: The study investigated the prospect of Macadamia biodiesel as a sustainable and alternative fuel for diesel engine in the transport sector in Australia. The crude vegetable oil is converted to biodiesel by the transesterification reaction with potassium methoxide as a catalyst at 60 °C for one hour. The fatty acid composition and fuel properties of the converted biodiesel are tested under the ASTM and EN standards and compared those with the properties of Ultra-low Sulphur diesel (ULSD). A 4 cylinder, four strokes, DI diesel engine performance and emission characteristics were studied using B5 (5% biodiesel + 95% ULSD by vol.) and B20 (20% biodiesel + 80% ULSD by vol.) blends. The experiment was conducted at full load condition by varying engine speed from 1200 rpm to 2400 rpm. The study examined the brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) as engine performance parameters and CO, CO2, HC, PM, NOx, and EGT as emission parameters and compared these with results of ULSD. The study found minimum BSFC and maximum BTE at 1600 rpm engine speed. The result reveals that Macadamia biodiesel has higher BSFC, about 5% (B5) to 10% (B20) and lower BTE, about 4.5% (B5) to 6.8% (B20) throughout the range of engine speed. Significant reduction in CO, HC, and PM emissions were found. More specifically, an average reduction of 26% (B5) to 40% (B20) in CO; about 9% (B5) to 31% (B20) in HC; 15% (B5) to 33% (B20) in PM emission were found compared to ULSD. However, the higher EGT of the biodiesel blends increases NOx emission, about 21% to 27% compared to ULSD. Further study on tribological characteristics of Macadamia biodiesel is recommended before any commercial application can be made
Residential house energy rating in Australia by Firoz Alam( )

1 edition published in 2009 in Undetermined and held by 1 WorldCat member library worldwide

All newly built residential buildings are required to comply with the energy efficiency measures introduced by all the states and territories in Australia since 2003. The measure of energy efficiency is determined using various computer based simulation tools (software) in the form of star rating ranging from 1 to 10. Generally the higher the star rating, the better the efficiency of energy used by the house. A number of simulation software tools are available to predict the energy rating. The primary objective of this paper is to review various computer based simulation tools currently used in Australia and the relative advantages of these tools. A brief description of each software is also furnished. The review revealed that several second generation simulation tools can predict better energy efficiency compared to first generation simulation tools. However, studies are required to evaluate these second generation tools as currently scant information is available to the public domain about their performance

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

Bubble rise through a liquid is an important phenomenon in the engineering practice. Bubbles are used in polymer, metallurgy, biotechnology and especially in process industries for improving the heat and mass transfer. An experimental investigation on the bubble rise velocity and trajectory in a stagnant water column under different pressure and vacuum is presented in this study. The experiments were conducted at water heights of 1 m, 1.2 m, 1.4 m and 1.6 m by introducing different bubble volumes (0.1 mL 15.0 mL) corresponding to each height. The bubble rise velocity and trajectory were measured using a combination of non-intrusive (high speed photographic) method and digital image processing. The parameters that significantly affect the rise of air bubble are identified. The effect of different water heights and bubble volumes on the bubble rise velocity and trajectory is analysed and the influence of two different sizes of tubes on the bubble velocity for various bubble volume is discussed
Performance and Emission Characteristics of Binary Mixture of Poppy and Waste Cooking Biodiesel( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: An experimental study was conducted on a compression ignition (CI) engine using neat diesel and binary mixture of poppy and waste cooking (PWC) biodiesel-diesel blends. Biodiesel-diesel blends of B5, B10 and B20 for PWC were used in this investigation. The experiment was conducted for different engine speed (1200 rpm-2400 rpm) and load (25%, 50%, 75% and 100%). The speed of the engine was varied from 1200 rpm to 2400 rpm with 200 rpm interval. The performance of the engine output is presented in terms of brake power (BP), torque, brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE). The emission characteristics, such as nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbon (HC) and particulate matter (PM) are also presented in this study. The results indicate that BP increases with increase in speed up to the maximum speed of 2400 rpm, whereas, BSFC decreases initially up to 1400 rpm and then increases up to the maximum speed of 2400 rpm at full load condition. On the other hand, torque and BTE initially increases up to 1400 rpm, and then, decreases with increase in speed up to the maximum speed of 2400 rpm. The results revealed that BP, torque, BSFC and BTE are lower in biodiesel blends in comparison to diesel. The engine performance and emission characteristics are compared with diesel. The results revealed that the use of biodiesel-diesel blends led to the significant reduction in carbon monoxide (CO), hydrocarbon (HC) and particulate matter (PM) emissions in comparison to conventional diesel at full load condition. On the other hand, increase in nitrogen oxides (NOx) is observed in using biodiesel blends over the diesel

1 edition published in 2007 in Undetermined and held by 1 WorldCat member library worldwide

This study investigated and analysed a suitable gas-fired power generator set required for producing electricity from waste coal seam methane which is being drained from coal mines in the Bowen Basis area of Central Queensland, Australia. The volume flow rate of waste/drained coal seam methane (CSM) is approximately 2000 m3/h. A literature review on current operations and the processes used in the industry for methane power generation is presented. Design, analysis and calculation required for the selection of major components of a gas-fired power generator, proposed for coal seam methane power generation, is discussed. The generator should be a single unit which is capable of being transported to site to provide a short term or long term solution to waste methane drainage. This study reports that a unit employing an in-line 8 cylinder Caterpillar engine with a Stamford ac generator and a filtration system comprising Nowata and Dungs filtration equipment would make up the major components of a gas-fired power generator suitable for producing electricity from waste/drained coal seam methane
