Download or read book Dynamic Simulation of the Chemical Looping Combustion Process written by Johannes Haus and published by Cuvillier Verlag. This book was released on 2020-12-09 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Ph.D. thesis a system of coupled fluidized bed reactors is modelled and simulated dynamically. Chemical Looping Combustion was used as an exemplary process in both the numerical and the experimental part of this work. For the simulation purpose a novel flowsheeting software was used and models for the needed process units developed and integrated into this software. The needed unit models were three interconnected fluidized bed reactors in circulating and bubbling operation conditions, a cyclone for gas-solid separation and loop seals, which ensured solids transport and gas separation between the reactors. Additionally, lab scale experiments on the reactivity of the used solids, oxygen carrier and solid fuels, were conducted and kinetic parameters extracted. All unit models were connected to a process flowsheet and simulated dynamically. The simulation results were compared to experimental data from a 25 kWth pilot plant operated at the university by the author. It could be shown that a detailed and dynamic simulation of the whole process can be carried out over a time period of more than 45 minutes and the experimental results from start-up, steady state operation and shutdown of the plant were predicted accurately.

Available in PDF, EPUB and Kindle. Book excerpt: Faced with an ever-growing resource scarcity and environmental regulations, the last 30 years have witnessed the rapid development of various renewable power sources, such as wind, tidal, and solar power generation. The variable and uncertain nature of these resources is well-known, while the utilization of power electronic converters presents new challenges for the stability of the power grid. Consequently, various control and operational strategies have been proposed and implemented by the industry and research community, with a growing requirement for flexibility and load regulation placed on conventional thermal power generation. Against this background, the modelling and control of conventional thermal engines, such as those based on diesel and gasoline, are experiencing serious obstacles when facing increasing environmental concerns. Efficient control that can fulfill the requirements of high efficiency, low pollution, and long durability is an emerging requirement. The modelling, simulation, and control of thermal energy systems are key to providing innovative and effective solutions. Through applying detailed dynamic modelling, a thorough understanding of the thermal conversion mechanism(s) can be achieved, based on which advanced control strategies can be designed to improve the performance of the thermal energy system, both in economic and environmental terms. Simulation studies and test beds are also of great significance for these research activities prior to proceeding to field tests.

This book was released on 1998-06-17 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: The school held at Villa Marigola, Lerici, Italy, in July 1997 was very much an educational experiment aimed not just at teaching a new generation of students the latest developments in computer simulation methods and theory, but also at bringing together researchers from the condensed matter computer simulation community, the biophysical chemistry community and the quantum dynamics community to confront the shared problem: the development of methods to treat the dynamics of quantum condensed phase systems.This volume collects the lectures delivered there. Due to the focus of the school, the contributions divide along natural lines into two broad groups: (1) the most sophisticated forms of the art of computer simulation, including biased phase space sampling schemes, methods which address the multiplicity of time scales in condensed phase problems, and static equilibrium methods for treating quantum systems; (2) the contributions on quantum dynamics, including methods for mixing quantum and classical dynamics in condensed phase simulations and methods capable of treating all degrees of freedom quantum-mechanically.
