Performance Analysis of Bio-Energy Based Power Generation System in Nigeria Using Rice Husk Feedstock (Published)
Bio-energy which is the energy resources derived from organic matter has contributed significantly to primary energy supply in most developed countries of the world. The extensive use of biomass for electricity generation started recently as a more efficient option of providing energy. To encourage investment in this area, detail analysis on the prospect of Biomass energy generation system in Nigeria context need to be carried out. In line with this, this study assesses the viability of setting up a Biomass Energy Plant in Nigeria using rice husk. It determine the availability of rice husk for the project and identify the economic advantage of using rice husk as a feedstock in generating electricity while evaluating the energy conversion technology adopted with consideration on its environmental impact. The proposed plant location is Abakiliki Rice Mill complex and Gasification technology was adopted for the bio conversion process. Data on the feedstock availability was collected by direct measurement of the resources at the various mill dump site in the Rice Mill Complex and analyzed using Python analytical and visualization tools (Numpy and Seaborn). The primary source of data for the analysis is data gotten from the field and Nigeria Energy Regulatory Council (NERC) while the secondary source of data is data from related work over the internet. The outcome of the study showed that the Rice Complex have the capacity to produce the quantity of rice husk required to generate 499,320KWh of electricity per year using Bio-Energy plant. Also, the mass of rice husk produced is significantly higher in the month of October, November and December due to the weather condition (dry season) and the high demand of rice as the result of the festivity (Christmas celebration). When the performance of the existing system and the proposed Bio-Energy plant was compared in terms of per Kilowatt cost of energy generation, it was observed that the new system outperformed the existing one. This is traceable to the good caloric value of rice husk and its availability in very large quantity at no cost. To determine the system’s sustainability, the financial feasibility of operating a Biomass plant in Nigeria was also carried out; levelised cost, simple payback period and return on investment (ROI) as important financial metrics were calculated using real data.

Discussions on climate change have focused mainly on the negative impact on the environment and how to mitigate these and adapt to, different mitigation and adaptation measures available today, which are economically potential as proposed by IPCC. This paper looks at potentials that can be harnessed from increase in rice husk generation in Ebonyi State due to provisions of improved rice seedling by the present government of the state as an adaptation strategy to climate change. The paper establishes that to properly harness the economic potential of adaptation strategies of climate change among rural farmers, these farmers need to be educated because majority of them are illiterate and are ignorant of the consequences of their actions, and that the educator should adopt conscientization strategy as mode of facilitating learning.
Production of Ceramic Candle Water Filters Using Saw Dust, Rice Husk As Burnt Out Materials (Published)
Water is a commodity that every family needs on a daily basis, but unfortunately most of the sources of water available to people in the developing nations is nothing to write home about as treated water is not easy to come by. There is no doubt therefore that there is an urgent need for small, affordable water treatment facilities that the people can easily access. This study was designed to investigate the effectiveness of rate of flow through ceramic candle filters when locally available raw materials such as hardwood sawdust and rice husk are used as burn out materials components in the production of water ceramic candle filters. Three different water candle filters were produced using Ekulu coal deposit clay as the major raw material. With sawdust in ratio of 2:8 with the clay and rice husk in the ration 2: 8 also as the combustible (burnout) materials. Water flow rate were measured for the ceramic candle filters produced by measuring the volume of filtrate. It was observed that the filter that had sawdust as burntout materials yielded a filtrate of 100ml in 2 hours, 900ml in 6 hours and 1,500ml in 12 hours and the candle filter with rice husk yielded a filtrate volume of 90ml in 2 hours, 120ml in 6 hours and 220ml in 12 hours. The low yield of the candle filter with rice husk was due to the inability of the husk to be burnt off at temperature 9000C and below
