1. Internal Tar/CH4 Reforming in Biomass Dual Fluidised Bed Gasifiers towards Fuel Synthesis
Abstract : Production of high-quality syngas from biomass gasification in a dual fluidised bed gasifier (DFBG) has made a significant progress in R&D and Technology demonstration. An S&M scale bio-automotive fuel plant close to the feedstock resources is preferable as biomass feedstock is widely sparse and has relatively low density, low heating value and high moisture content.

2. Investigation of Solid Fuel Conversion in a Fluidised Bed Gasifier – Modelling and Experiments
Abstract : A substantial proportion of Sweden’s greenhouse gas emissions originates from the transportation sector, and the Swedish government has set the goal that the entire Swedish vehicle fleet will be independent from fossil fuels by 2030. One of the strategies investigated to achieve this goal is biomass gasification, which is a technology that can be used to transform lignocellulosic materials into a raw gas. READ MORE

3. Gas Mixing in a Circulating Fluidised Bed Boiler
Abstract : The present thesis is a study on the gas-mixing behaviour in a circulating fluidised bed (CFB) boiler. The aim is to describe how gas is spread in different regions of a CFB furnace and to explain variations in the mixing rate under different operating conditions. READ MORE

4. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia
Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE

5. High Temperature Corrosion in Fluidised Bed Environment
Abstract : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. READ MORE
