1. Co-firing animal waste, sludge, residue wood, peat and forest fuels in a 50MWth CFB boiler : ash transformation, availability and process improvements
Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE

2. Sintering in the Kraft Pulp Mill - Studies in the Rotary Kiln and Recovery Boiler
Abstract : The conversion of black liquor to white liquor is carried out in the chemical recovery system, which is made up of several units; in two of them, i.e. the recovery boiler and the rotary kiln, sintering plays an important role. READ MORE

3. 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.

5. Analysing performance of bio-refinery systems by integrating black liquor gasification with chemical pulp mills
Abstract : Mitigation of climate change and energy security are major driving forces for increased biomass utilization. The pulp and paper industry consumes a large proportion of the biomass worldwide including bark, wood residues, and black liquor. READ MORE
