ABSTRACT
The issue of energy shortage in Nigeria has been a concern for both the Nigerian government and the people for the past four decades. Other countries with similar problems have long overcome the predicament, Nigeria still looms in darkness. The Main energy challenges that face Nigeria presently is how to increase energy supplies to meet the needs of its growing population. This research is set on foot to discover a new renewable source of energy for producing the necessary heating source for boiler firing at an affordable cost which will automatically result to low-pressure energy utilization. A detailed boiler design and turbine design with the fabrication of the component/parts, assembly and testing was carried out. The selection of standard locally available materials that can withstand the operating conditions of the system was also considered. Split-Split plot (SSP) experimental design was used to identify appropriate specie of mangrove wood with respect to location that gave optimum calorific value. Factorial analysis was used to analyze variables that influence boiler performance and check the level of agreement among the knowledgeable persons who ranked the performance variables in descending order of importance. Response Surface Methodology (RSM) was used to model and optimize the Calorific Value of various biomass (mangrove wood species and rubber wood) identified from the different locations. Kolmogrorov-Smirnov and AndersonDarling test were used to obtain the 95% confidence interval at which the ranks for the sensitivity analysis were determined.
