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. 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. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society
Abstract : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. READ MORE

4. Availability Analysis of Three Different Types of Combined Cycle Power Plants
Abstract : The goal of power plants with higher efficiency and lower environmental risk than conventional power plants has produced three types of combined cycle power plants. These are: 1) the conventional combined cycle (CCC) power plant, 2) the pressurised fluidised bed combustion (PFBC) power plants, and 3) the integrated gasification combined cycle (IGCC) power plants.

5. Reducing Alkali Chloride-Induced High Temperature Corrosion by Sulphur Containing Additives – A Combined Laboratory and Field Study
Abstract : In order to achieve a more sustainable society renewable fuels such as biomass and waste are attractive alternatives to fossil fuels for power production. However, fireside corrosion is a serious concern in boilers combusting biomass or waste. The high corrosion rates are often linked to large amounts of alkali chlorides in the flue gas. READ MORE
