Abstract
Straw is a typical high volatile, cellulose-based fuel with moderate moisture and low ash. The very low bulk and energy density will present serious fuel feeding and combustion difficulties on conventional plant. The cereal straw ashes and the straw-coal ash mixtures have very low Ash Fusion Temperatures. The oil seed rape straw ashes are more refractory. The principle constituents of straw ash are amorphous silica, calcium and magnesium carbonates and potassium phosphates. The SO{sub 2} uptake occurs over the temperature range 400-1050{sup o}C and the level of uptake depends on the CaO content of the ash. Oil seed rape ashes generally had high SO{sub 2} uptake levels while the cereal straws uptake was very low. The relatively high potassium content and the high availability of alkali metals above 800{sup o}C indicates there is likely to be serious problems with fouling deposits. (author).
