1. The Survey of Ash Agglomeration Phenomena in a Commercial Circulating Fluidised Bed (CFB)
Abstract : Renewable energy sources will act an important roll in the development of sustainability in the future in order to protect environment and ecological cycle.Amongst the Kyoto protocol conclusions there is an agreements for the EU a reduction of 8 % of greenhouse gas emissions (corresponding of around 6 million tonnes of CO2 equivalents ) between 2008-2012 (compared to 1990 level).

2. Co-firing complex biomass in a CFB boiler : ash transformation, corrosion control and materials selection
Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

3. Design and Operation of a Chemical-Looping Reformer for Catalytic Upgrading of Biomass-Derived Gas
Abstract : AbstractThe removal of tar from the raw gas produced during biomass gasification is necessary before the gas can be used as a feedstock for synthetic fuels. The currently commercially available technologies for gas cleaning, i.e. READ MORE

4. Erosion - Corrosion Resistance and Adhesion of Laser and Thermally Deposited Coatings in Fluidised Beds
Abstract : High temperature erosion - corrosion is the major source for degradation of components such as heat exchangers, tubes, cyclones and water walls used in Fluidised Bed Combustion (FBC) plants. By coating the exposed components with a protective material, the degradation rate can be decreased. 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
