21. Biomass Energy Systems and Resources in Tropical Tanzania
Sammanfattning : Tanzania has a characteristic developing economy, which is dependent on agricultural productivity. About 90% of the total primary energy consumption of the country is from biomass. Since the biomass is mostly consumed at the household level in form of wood fuel, it is marginally contributing to the commercial energy supply. LÄS MER
22. Computational Fluid Dynamics Modeling of Biomass Gasification in Fixed-bed Reactors Using Highly Preheated Agent
Sammanfattning : Biomass gasification is considered to be one of the most promising energy recovery technologies for the widespread utilization of biomass. Mathematical models have been developed to understand the gasification process inside gasifiers. LÄS MER
23. Enhancing the circular economy: Resource recovery through thermochemical conversion processes of landfill waste and biomass
Sammanfattning : Currently, the global economy looses a considerable amount of potential secondary raw materials from the disposed waste streams. Furthermore, the existing landfill sites that often do not have proper environmental protection technologies pose a long-lasting risk for the environment, which urge immediate actions for landfill remediations.

24. Mathematical modeling of municipal solid waste plasma gasification in a fixed-bed melting reactor
Sammanfattning : The increasing yield of municipal solid waste (MSW) is one of the main by-products of modern society. Among various MSW treatment methods, plasma gasification in a fixed-bed melting reactor (PGM) is a new technology, which may provide an efficient and environmental friendly solution for problems related to MSW disposals.

25. Micro-reaction Mechanism Study of the Biomass Thermal Conversion Process using Density Functional Theory
Sammanfattning : Biomass, or bio-energy, is one of the most important alternative energies because of environmental concerns and the future shortage of fossil fuels. Multi-scaled bioenergy studies have been performed in the division of Energy and Furnace Technology, which included studies of macroscopic systems such as systems and reactors, modeling of computational fluid dynamics (CFD), and atomic/molecular level studies.
