2. 1. Interactions between calcium and heavy metals in Norway spruce : Accumulation and binding of metals in wood and bark

   Author : Ann Helén Österås; Maria Greger; Lena Kautsky; Douglas L. Godbold; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi;

   Abstract : Waste products from the forest industry are to be spread in forests in Sweden to counteract nutrient depletion due to whole tree harvesting. This may increase the bioavailability of calcium (Ca) and heavy metals, such as cadmium (Cd), copper (Cu) and zinc (Zn) in forest soils. READ MORE

4. 2. Co-combustion of Biomass and Waste Fuels in a Fluidised Bed Boiler - Fuel Synergism

   Author : Anna-Lena Elled; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-combustion; fluidised bed combustion; straw; municipal sewage sludge; deposit formation; ash composition; biomass; wood;

   Abstract : The objective of this work was to study co-combustion of biomass and waste fuels in a circulating fluidised bed boiler and to detect synergy effects with respect to flue gas composition and ash formation during boiler operation. It was also the aim to perform supplementary thermodynamic equilibrium calculations in order to support the experimental results. READ MORE
