1. The Corrosive Effect of Chlorine Containing Species on Waterwalls and Superheater Materials in Waste and Biomass-Fired Power Plants
Abstract : To increase power generation from waste- and biomass-fired boilers, it is necessary to increase the temperature and pressure of the steam generated. This implies an increase in the temperature both of the waterwalls and of the steam superheaters in the boiler. READ MORE

2. In-Nozzle Flow, Spray and Combustion Investigations of Two-Stroke Marine Diesel Engine Fuel Injectors
Abstract : This thesis focuses on the experimental studies of the cavitating in-nozzle flow of large two-stroke marine Diesel engine fuel injector nozzles and how it affects the spray morphology and combustion behaviour. To further increase the efficiency of large two-stroke marine Diesel engines, a better understanding of the fuel spray atomization process is necessary. READ MORE

3. Deposit Induced Corrosion in Biofuel Combustion
Abstract : Deposit induced corrosion is one of the main mechanisms for attack on heat exchangers in biofuel boilers. This severe corrosion decreases the obtainable steam temperature in boilers, thereby the efficiency in production of electricity is reduced. Deposit formation from the gas on superheater tubes are is generally referred to as fouling. READ MORE

4. Measurement and Control of Metal Vapours during Fluidized Bed Combustion of Biomass Fuels
Abstract : Increased combustion of biomass fuels for heat and power production has created a need to recycle nutrient elements in biomass ash to soils to make the biomass consumption sustainable. It is, however, difficult to recycle the total amount of biomass ash produced due to the high concentrations of heavy metals and their readily soluble forms in some ash fractions. READ MORE

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