CASE REPORT. A 68 -year old woman presented to the geriatric medical unit with severe chronic varicose ulceration of the lower limbs. This had been present for over twenty years and had resulted in her spending two out of the past three years in hospital. She had been discharged from a dermatology unit less than three months earlier. Her ulcers were associated with marked oedema of the legs. Sh...

The behaviour of alkali metals, especially of potassium, during circulating fluidised bed combustion of wood-based fuels was studied experimentally in pilot-scale and industrial scale combustors. The fuels included willow, forest residue and waste wood co-combusted with paper mill sludge. As a result of this work, the main chemical and physical transformation mechanisms of potassium compounds i...

Waste tyres gasification in a bubbling fluidised bed reactor is evaluated by means of complete characterisation the product gas. The experiments are carried out at two temperatures, 700 and 850 °C, various equivalence ratios (ER) while using air as gasifying. Additionally, effect steam also studied °C. High temperature low ER increase production H2, CH4, C2H4. Steam addition mainly affects H2 C...

The drying of solids in a continuously worked vibrated fluidised bed dryer is studied by simulations. A model considering the drying of a thin layer of particles wetted with a multicomponent mixture is developed. Particles are assumed well mixed in the direction of the airflow and only the longitudinal changes of liquid content, liquid composition and particle temperature are considered. Intera...
