 thesis and an outline on Combustion, Fuel and Energy


 thesis and an outline on Combustion, Fuel and Energy. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The results obtained deviated from the theoretical values.

The generation of power and sustainable heat from biomass is at the center of scientific and industrial interests because of the increasing awareness of the reduction of fossil fuels and the higher appreciation towards environmental conservation from pollutants produced by energetic systems [1]. Short-cycle carbon that is essential for future energy needs is obtained from biomass [2]. Several factors are known to affect the process of biomass combustion including the kinetics of decomposition, biomass particle size, biomass moisture content and metal content of the biomass.

A lot of research has been conducted on kinetic studies of biomass thermal decomposition because it is an important step in the combustion of biomass. Modeling of combustion processes and kinetics of reactors require the knowledge of the kinetics. The composition, quantities and release of volatiles from the biomass affect the stability, temperature profiles and flame ignition, stability, and temperature profiles in the radiant part of furnaces. The factors mentioned above influence the NOx reduction mechanisms and are, therefore, important in designing burners in pulverized fuel power stations. In the study of the kinetics of thermal decomposition, slow pyrolysis and first-order reaction kinetics has been made.

Where α represents the progress of the reaction and its value ranges from 0 to 1, m is the sample current weight, mo is the sample initial weight, and k represents rate constant of the reaction. The rate constant is typically given by the Arrhenius function:

The most widely used mathematical method in the derivation of activation energy and pre-exponential factor based on TGA experiments is the reaction rate constant method. Assuming the weight loss with the time curve is a result of one or more first-order reactions.
