Research ArticleOpen accessIn the keywordsIntegrating Renewable and Nonrenewable Energies in Power Plant PlanningHabib H. Al-Ali, Yousef Saif, Ali Elkamel, Ali LohiProblem statement: Electricity can be generated from different type of technologies such as fossil and non-fossil power plants. Among these technologies, coal-fired power plants have been a major route for electricity generation. Recently, environmental constraints were imposed over the coal power plant operations in order to reduce their emissions. Besides, renewable energy power plants such as hydroelectric, wind, solar and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,804 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOil Palm Biomass As Potential Substitution Raw Materials For Commercial Biomass Briquettes ProductionA.B. Nasrin, A.N. Ma, Y.M. Choo et al.Palm oil industry generates vast amount of palm biomass. Converting palm biomass into a uniform and solid fuel through briquetting process appears to be an attractive solution in upgrading its properties and add value. In this study, raw materials including empty fruit bunch (EFB), in powder and fibre forms, palm kernel expeller (PKE) and sawdust were densified into briquettes at … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 9,472 accessesView PDFCite
