“…One way to overcome some problems with agglomeration is to use a mixture of biomass and peat in order to increase the melting point of the raw material in the furnace. It is also possible to use lime (which contains CaO and other Ca salts) instead of quartz in the fluidized bed reactor to increase the agglomeration temperature of some biomass types under the gasification conditions [40].…”

The transport sector generates a lot of emissions of different gases and particles in the air. The gases are released by combustion of different fossil fuels in car engines. These emissions have a negative effect on human health and are also now known to cause vast environmental changes. Several of these gases are greenhouse gases such as CO 2 , CH 4 , N 2 O, etc. There is very strong evidence of a correlation between greenhouse gases and worldwide weather changes resulting in global warming. These negative environmental effects together with increasing energy demands in the world and depletion of fossil fuels in the near future, in combination with longdistance transport have had a positive impact on developing new energy sources. Bioenergy (energy derived from biological sources) production from renewable resources has increased during recent decades. World energy demand has dramatically increased and new sources of energy, beside fossil resources, are needed. The European Union is prompting its member states to increase their use of biofuels to meet a target share of 5.75% of the total fuel market by 2010. However, they had only reached an average share of 1.4% of the biofuel usage for all member states in 2005. To meet the EU target it is necessary to act in several different areas and develop several different bioenergy products, depending on regional possibilities Introduction to Chemicals from Biomass Edited by James Clark and Fabien Deswarte

“…Bed agglomeration is often a precursor to the unscheduled shut-down of fluidised bed gasifiers [4] and is the foremost ash-related problem affecting the performance of fluidised beds. The alkali content of the biomass is seen as the main contributor [5].…”

Analysis of bed agglomeration during gasification of wheat straw in a bubbling fluidised bed gasifier using mullite as bed material

The quantity and composition of the ash content of straw poses technical challenges to its thermal conversion and have been widely reported to cause severe ash sintering and bed agglomeration during fluidised bed gasification. Literature indicates that a combination of reactor design and bed material measures is required to avoid defluidisation at temperatures above 800 °C. Using scanning electron microscopy and energy dispersive X-ray spectroscopy this study investigated the initial agglomeration of a mullite bed during the
