Abstract Stellite-6 (Co-based) and NiAl coatings (Ni-based) were deposited via HVOF spraying onto 304 stainless steels tested in a 20 kWth biomass fired bubbling fluidised bed (BFB) combustor for 20 h an industrial scale anthracite CFB boiler 1630 h. showed excellent corrosion resistance both combustion systems because of the formation outermost Cr2O3 layer spinel CoCr2O4 beneath, whereas coati...

The presence of polycyclic aromatic hydrocarbons (PAH) in the oil obtained at pyrolysis of Jordan oil shale in a fluidised-bed reactor in the atmosphere of nitrogen and nitrogen/steam has been investigated. The final pyrolysis temperature was 520 °C, at which the maximum oil yield was established. The derived oils were fractionated into chemical classes using mini-column liquid chromatography f...

A novel equilibrium reaction modelling approach is proposed for the efficient design of biomass gasifiers. Fuels and chars are defined as pseudo species with properties derived from their ultimate analyses; tars as a subset of known molecular species and their distribution determined by equilibrium calculations. Non-equilibrium behaviour for gas, tar, and char formation is explained by reaction...
