1. Fluid Dynamics of the Bottom Bed of Circulating Fluidized Bed Boilers
Abstract : The fluid dynamic conditions in the furnace of a fluidized bed boiler influence the combustion and the production of harmful emissions. A substantial amount of the bed material in a circulating fluidized bed (CFB) boiler is present as a dense bubbling bottom bed. READ MORE

2. Reduction of the N2O Emission from Fluidized Bed Combustion by Afterburning
Abstract : A method for reducing N2O emissions from fluidized bed combustion is presented and investigated. In contrast to flame combustion, fluidized bed combustion generates significant amounts of nitrous oxide (N2O) which are emitted to the atmosphere. 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. Use of Bed Materials in Dual Fluidized Bed (DFB) Systems
Abstract : Dual Fluidized Bed (DFB) gasification is one alternative for the production of biofuels. In a DFB gasification process, the bed material plays a crucial role. Primary role of the bed material is to provide the heat needed for the gasification reaction. READ MORE
