The Selection Process of Biomass Materials for the Production of Bio-Fuels and Co-firing (eBook, ePUB)

• Format: ePub

Produktbeschreibung

A functional discussion of the crop selection process for biomass energy The Selection Process of Biomass Materials for the Production of Bio-fuels and Co-firing provides a detailed examination and analysis for a number of energy crops and their use as a source for generating electricity and for the production of bio-fuels. Renowned renewable energy expert and consultant Dr. Najib Altawell begins with the fundamentals of bio-fuels and co-firing and moves on to the main feature, which is the methodology that assists energy scientists and engineers to arrive at the most suitable biomass materials tailored to each company's business and economic environments and objectives. This methodology provides a framework whereby power-generating companies can insert their own values for each factor, whether business factor (BF) or scientific & technical factors (S&T) or both simultaneously. The methodology provides a list of factors related to the biomass energy business. The average values have been obtained from the survey method and laboratory tests. These values are the standard values power companies can use if they need or wish to use them. The Selection Process of Biomass Materials for the Production of Bio-fuels and Co-firing has been designed and compiled for the widest possible range of readers, researchers, businesspeople, and economists who are connected to the renewable energy field in general, and biomass energy in particular. Because of its focus on practical data and applications, the book is also accessible for general readers who may or may not have a technical or scientific background.
