Designing Oil Fired Power Plant Incorporated with Renewable Energy and Analyzing Capacity Improvement Engr. Bony Francis Rozario, Dr. Mohammad Abdul Mannan Abstract— Global electricity generation contributed from Oil fired power plants is 1,103 TWh, which is around 5.5% of the total generation capacity. The amount is said to increase in the upcoming years by 2-3%. Considering the fact, gas emissions [NOx (2,000 mg/Nm 3 ), SOx (2,000 mg/Nm 3 ), and Particular Molecule (50 mg /Nm3) per 100 MW] of these plants equivalently have immense environmental impact. Rendering the consequences the design has been focused to mitigate the impacts incorporating green energies such as solar system, wind energy and cogenerations. The incorporation will also improve the overall capacity as well as efficiency. The efficiency of FO power plant is around 45% depending on the alternators’ rated capacity and engine’s fuel consumption ability at flat 80% plant factor. The design primarily emphasizes on ‘generated heat’ for certain fuel consuming engines which is to be extracted and in-conjunction of a steam turbine (referred to as ‘cogeneration’) the net output shall be increased by 0.38% (approx.). The gas emission velocity through exhaust stack shall also be utilized with the help of VAWT (Vertical Axis Wind Turbine) to utilize certain amount of energy. The preference has been focused to VAWT operated through emitted gas which enables the mounting at the edge of exhaust stack more feasible and practical. The design also incorporates solar panel to be placed at the roof top of power (engine) house occupying 37% of the entire plant area. These three separate energy sources can be incorporated in each of the existing plants for a comprehensive effect to overall outcome of the electricity generation. The paper has been segmented to improvise these design outcomes based on a 100 MW (Net) HFO power plant. The simulation comprises real data collected from various operating plant as to ease the merging of theoretical results with practical implications.

Given significant electricity supply-to-usage ratios, the daily demand of electricity is increasing at an alarming rate i.e. 20 billion kwh/year [1]. These generation mostly rely upon the availability of different resources such as natural gas, petroleum product, coal etc. which on the other hand also is in the verge of scarcity. Accordingly the generating stations emitting NOx, SOx, and hazardous 29,000 Mt (approx.) CO2 [4] implying a disastrous environmental impact. In addition, conventional power plants are subjected to limited resources and causes of global warming, greenhouse effect, acid rain, moreover electricity tariff is increasing at about 8 to 10% p.a. on an average [5]. Whereas, renewable energy systems that take advantage of energy sources that won’t diminish over time and are independent of fluctuations in price and availability are playing an ever-increasing role in modern power systems. In other words, renewable energy is energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources, with 10% of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewables [6]. In case of FO (Fuel Oil) power plant particularly, burning oil for electricity generation causes both local and international environmental and human health impacts. Depending on operating life and non-operative routine maintenance most of the oil fired plant could cause stimulus black smoke and sulphurous pollution associated with heavy oil burning [1]. Local atmospheric impacts that can be expected would be high levels of sulphur dioxide (SO2) emissions and oxides of nitrogen (NOx) as well as fine particulates. Rendering the consequence, this paper work emphasizes on mitigating the harmful effects of Oil fired power plant operating worldwide with greener energy. The non- replaceable plants might be an ideal option for practical implication of this paper work. The green energies segregated for the paper work are Solar Power, Wind Power and Cogeneration. These renewable energies will be additive to the oil fired plants without distracting the normal operational process of the plant. Greener energies might be treated as additional power resources improvising the oil fired plant’s performance capacity and/or efficiency. The below block diagram (Figure 1) provides the main focus of the paper work in simplest form possible. Figure 1: Block Representation of Paper Work The addition of solar and wind power will enhance the plant capacity in green methodology, whereas incorporation of renewable resource- cogeneration system will mitigate SOx, NOx and COx impacts on environment as well as reduce the fuel consumption by reducing fuel oil plant’s heat rate in an appreciable manner International Journal of Scientific & Engineering Research, Volume 5, Issue 7, July-2014 ISSN 2229-5518 1205 IJSER © 2014 http://www.ijser.org IJSER
