  • Modelling of a High Temperature Solid Oxide Fuel Cell

    • Authors: Pankaj Kalra, Rajeev Garg, Ajay Kumar
      Abstract: Solid oxide fuel cell (SOFC) has been considered as one of the most efficient power generation devices for the coming decades. There are various physical phenomena appearing in SOFC in multi-length and -time scales, such as multi-component gas-phase species/charge flow, thermal energy and mass transfer. Meanwhile, generation and consumption of gas and surface phase species together with electric current production are involved at various active sites of different components of SOFC.In this paper, a numerical study of the thermal and electrochemical performance of a single Integrated Planar Solid Oxide Fuel Cell (IP-SOFC) has been performed. The numerical modelling considers internal reforming through the methane reforming and water gas shift reactions in a Ni-YSZ anode. Next to the description of the electrochemical reactions, the methane/steam reforming and shift reactions, the heat-transfer and the mass-transfer processes have also been included in the model. Keywords: Solid oxide fuel cell (SOFC), Integrated Planar Solid Oxide Fuel Cell (IP-SOFC), internal reforming, methane reforming, water gas shift.

  • On Optimization of Air Pollution and Electricity Production of Thermal
           Power Plants of Delhi using Goal Programming

    • Authors: Rajesh Dangwal, Arvind Kumar, Vivek Naithani
      Abstract: Air pollution is a serious problem in today’s rapidly developing world. Burning of fossil fuels has been the source of air pollution since ages. Coal is a major source of electricity production in India. About 56% of total electricity produced is from Thermal Power Plants (TPPs). In Delhi we have taken 5 TPPs producing about 2800 MW of energy catering to the desire of the nation for this study.Sulphur dioxide (SO2), Oxides of Nitrogen (NOx), Total Suspended particulate matter (TSPM) are the main pollutants emitted from TPPs. Due to burning of coal in huge amount in TPPs a large amount of pollutants is emitted in the air. But on the contrary we cannot stop this process completely as coal is efficient as well as easily available resource in this day and other non conventional sources like solar, tidal, wind power etc. are in their infancy in the country. In this paper we are trying to optimize pollutants of air emitted from TPPs and electricity production in aggregate from 5 TPPs working in Delhi using a Goal Programming (GP) model. Keywords: Thermal Power Plant (TPP), SO2, NOx, TSPM, Optimization, Goal Programming (GP)

  • A Reliability Model on an APFC System with Three Stages of Working with
           Respect to Variation in Power Factor

    • Authors: Rekha ., Shilpi ., Gulshan Taneja
      Abstract: The present paper deals with the reliability and profit analysis of an automatic power factor controller (APFC) system with three stages of working with respect to variation in power factor. Power factor may vary and result into three categories: controlled, partially controlled and uncontrolled power factor. Due to poor power factor system, many industries have to face many problems like electric loads, energy loads and fuse replacement like. So, there is need to accurate/ appropriate these problems. Study of APFC system, therefore, is of great importance. In the present study, the system is initially operative with controlled factor, then it may transit to the mode where the power factor is partially controlled and vice versa. Also, from the partially controlled power factor mode, the system may transit to a  mode of uncontrolled power factor and vice versa. If the system fails, there is need to detect the type of failure by inspection. The type of failure may be 'Fuse blown off' or 'Transformer burnt' or 'Programme problem' or 'output relay faulty'. After repair/replacement on failure, the system goes back to the same controlling mode as was existing at the time of failure. Various measures of system effectiveness have been obtained by making use of regenerative point technique. Graphs have been plotted to draw interesting conclusions related to the revenue per unit up time, loss per unit time during which the power factor remains uncontrolled/partially controlled. Keywords:- Automatic Power Factor Control (APFC) System, Controlled/Partial Controlled/Uncontrolled Power factor, Measures of System effectiveness, Regenerative point  technique.

  • Investigation of Temperature and Flow Distribution in a Serially Connected
           Thermosyphon Solar Water Heating Collector System in Minna, Niger

    • Authors: Akanmu; W. P., Bajere, P. A.
      Abstract: Natural circulation solar water heating systems are designed and fabricated with varying collector geometries, materials, storage tank capacities and specifications of individual components. Despite the availability of theoretical and experimental studies including the test procedures, to estimate the performances of these systems, there are few experimental studies showing the temperature profiles of a particular collector geometries and materials with water temperature and flow rates in the units. This paper presents detailed experimental observations of temperature and flow distribution with solar radiations in a thermosyphon solar water heating system with four flat plate collectors, connected in series and using locally available materials, under a wide range of weather conditions of Minna for a whole year, to determine its suitability in meeting the hot water requirement for bathing in residential apartments. Results showed that the system is capable of meeting 70 – 100% hot water requirements and an average of 65.50C water temperatures is obtained daily with high temperatures reaching 90oC on excessive hot days of March to May annually. Water temperatures in the hot water tank are of the range 45oC to 78oC and a mass flow rate averaging 55kg/hr was achieved for the system. Detailed temperature distributions, solar radiations variations and mass flow rate of the system were determined and presented. The experimental results were compared to the results found in the literatures and they showed good agreement. Keywords: Flow measurement; Mean absorber plate temperature; Mean fluid temperature; Radiation measurement; Solar thermal collector system; Solar water heating system; Temperature measurement; Thermosyphon.

  • Comparative Study of Isotherms of Activated Carbons Produced from Mango
           Kernels and Commercial Activated Carbons (ISO 9001:2000)

    • Authors: Kwaghger; Aondona, Edeoja, Alex, Tile, Joseph
      Abstract: Waste handling and management has been a major challenge especially in the developing nations. Mango waste, with an estimated yield of 150,000 to 400,000 tons of wastes worldwide from mango processing, may cause environmental hazards. Exploring the suitability of and subsequent use of waste to replace commercial adsorbents in the area of adsorption refrigeration will address some of the waste management issues. Experimental studies of the isotherms of mango kernel activated carbons (MKAC) and that of commercial activated carbons (CAC- ISO 9001:2000) known to have suitable adsorption properties for both liquid and gas phase adsorption were carried out and compared to explore the potential of MKAC as a possible substitute. An experimental test rig was used to determine the isotherms of both MKAC- methanol and CAC- methanol refrigerant pairs. Desorption and adsorption isotherm for MKAC and CAC were determined and were observed to have same shape of curve (concave downwards). The shape of the isotherms observed from both pairs suggested the type I isotherms which are known to be highly microporous and as such suitable for gas phase adsorption. The isotherms show maximum desorption and adsorption capacities at pressure ranges of 2.5- 3.0 bar and 0.230- 0.240 bar respectively for MKAC and 2.7- 3.0 bar and 0.227 - 0.229 bar respectively for CAC. It was concluded that MKAC could be good substitute for commercially manufactured activated carbons for the design of gas phase adsorption cooling systems. Keywords: Activated carbons, Desorption; Adsorption, Isotherms, Mango kernels.

  • Energy Conservation Strategies and Peak Loads Management in Sever Climate

    • Authors: Hani H. Sait, Ahmad Hussain
      Abstract: Energy conservation aims to reduce energy consumption. Energy conservation can be achieved by the efficient use of energy, as well with the decreased of energy consumption and/or managing consumption of conventional energy sources. Energy conservation is positively enhanced financial capital, environmental quality, national security, personal security, and human comfort. Individuals and organizations that are direct consumers of energy can directly benefit from energy conservation if they choose to conserve energy to reduce energy costs and promote economic security. Industrial and commercial users can also maximize their profit by using energy efficiently. Peak load management is now becoming increasingly important for the Gulf region as well as countries with sever climate, as the growing energy demand is barely met by electric company’s capacity. A smart transmission system is needed to cope with the maximum load demands during peak hours; however, such system is very expensive. The utility of the smart transmission cannot be undermined keeping in view of that it can reduce the peak electrical demand and can save tremendous amounts of money for utilities, industry, and ratepayers. It is not enough to give attention to how much energy is consumed, but-now we must also pay more attention to when energy is consumed. Thermal storage has proven to be a commercial method for combating peak load demands. In addition to that the energy conservation strategies are being adopted in Saudi Arabia to cope up with the rapidly increase in electricity consumption. In this paper all the above mentioned have been discussed and solutions have been proposed.Keywords: energy conservation, energy consumption, peak load management, smart transmission

  • An Investigation of the Volatility Spillovers between the Stock Markets of
           Selected Members of OPEC and OPEC’s Oil Market using a Multivariate
           Dynamic Model

    • Authors: Hamed Sadri, Masoud Jafari
      Abstract: Stock market indices are under the influence of macroeconomic and non-economic conditions. The multiplicity and unknown nature of the factors that affect capital market has led to uncertainty in investments. Therefore, identification of the behavior of investors, the variables that affect stock price and returns, and the increasing expansion of capital markets by turning small individual investments into manufacturing activities are of utmost importance.The present article mainly focuses on modeling volatility and the resulting spillover effect in the stock market of certain members of OPEC using a multivariate VAR-BEKK model. It tries to examine volatility spillover between the studied countries as well as volatility spillover from the oil market to the stock market of these countries. The results show that oil price volatility has a significant spillover effect on stock market volatility in the selected members of OPEC. Moreover, stock market volatility in each of these countries and OPEC’s Oil Market volatility are significantly associated with market volatility in the other studied countries as well as with their past volatility. Keywords: money markets, OPEC members, multivariate GARCH models, volatility, spillover effect JEL Classification: C4, Q43, G1

  • Fluidised Bed Combustion: Towards Alternative Ways of Energy Recovery in
           Rural Nigeria

    • Authors: C. O. Folayan, G.Y. Pam, Yusuf Bello Habib
      Abstract: Modern energy poverty in rural Nigeria has been an on-going problem for decades. Over half of Nigeria’s population is estimated to be in the urban areas, with less than 40% of the rural community connected to the national grid partly due to high cost of rural electrification exercise. Hence the rural population continuously rely on direct burning of solid biomass (like fuel wood) as means of obtaining much needed energy for basic applications like cooking and heating. This collect and burn process consequently contributes to environmental concerns like climate change, acid deposition, environmental health and, deforestation, which has been identified as one of the leading causes of soil degradation. As the concept of sustainability shapes the fabric of the modern society, it is necessary to explore environmentally friendly methods of extracting biomass energy for rural use. One such means is energy recovery using fluidised bed combustors. This system uses agricultural waste as fuel source to produce heat energy for light load applications. The objective of this document therefore is to discuss the design and construction of a maize cobs fluidized bed combustor. Test results recorded high flue gas and bed temperatures of over 300?C and 850?C respectively, suitable for rural application including grain drying and water boiling. Keywords: Fluidise, maize, temperature, energy, flue gas

  • An Energy Approach to Evaluation of Carbon Dioxide Emissions from
           Kenya’s Road Freight Transport

    • Authors: David Odeyo Abiero, Xavier Francis Ochieng, Josiah Ochieng Odalo
      Abstract: Information on carbon emission from the different sectors in Kenya is scant. This research was conducted in Kenya in December 20211 with the objective of establishing the fuel efficiency and the associated Carbon dioxide(CO2) emission from the road freight transport between the port of Mombasa to the capital city of Nairobi along the northern corridor. This was achieved through a week long survey for outbound fright trucks. The fuel efficiency and the CO2 emitted were then derived using both the activity approach and the energy approach. The mean fuel efficiency on actual load found was 0.01327 Litres of diesel/ Ton-Km. The two approaches to the calculation of carbon dioxide emission gave different values with the activity based approach giving 595204.4 Tonnes while the energy based approach gave 315635.157 Tonnes of CO2 per a num. This level of emission from a road section is high and calls for urgent mitigation measures. Keywords: CO2 emission; fuel efficiency; Road freight transport; Ton-Kilometre.

  • Analysis of Wind and Solar Energy Potential in Eldoret, Kenya

    • Authors: Kipchirchir Choge
      Abstract: As a developing nation, Kenya urgently needs new sources of affordable, clean and renewable energy. Wind and solar energy are potentially attractive because of their low environmental impact, availability and sustainability. This work investigated the wind and solar power production potential in Eldoret, Kenya. Wind speed and sunshine duration data over a five-year period (2004-2008) from Eldoret meteorological station (0.53oN, 35.28oE) are presented. Wind power densities, seasonal variations of speed, and estimates of power likely to be produced by small wind turbines (WT’s) are included. The site investigated is found to be a class 2 wind power site with annual average wind speed of 2.5 m/s at 2 m height and power density of 80.379 W/m2 at 20 m height. The site is, therefore, likely to be suitable for wind farms as well as small, stand............
