A laboratory-scale, externally heated, rotary-kiln pyrolyser was designed and built. Pyrolysis tests were performed. Solid wastes (paper, paperboard, waste plastics including PVC and PE, rubber, vegetal materials, wood, and orange husk) were tested. The effects of heating methods, moisture...

A numerical model for gas-particle flow dynamics has been combined with an NOx chemistry post-processor to predict the formation of nitric oxide in a three-dimensional, W-shaped boiler furnace burning pulverized fuel. The model includes complex interactions in gas-particle turbulent flow, heat...

A new approach using both Eulerian and Lagrangian coordinates and taking account of inter-particle interactions has been developed for the study of gas–solid flows. A numerical algorithm is presented. Comparison with experimental results shows reasonably good agreement.

Numerical simulations of gas-solid flows, heat transfer and gas-particle combustion have been conducted for a three-dimensional, W-shaped boiler furnace. The gas-particle flow, distributions of temperature and concentrations of gaseous constituents, distributions of the rates of heat release,...

A first- and second-law analysis is presented for a process developed for simultaneous generation of a fuel gas and electric power (gas and power cogeneration) based on atmospheric circulating-fluidized-bed (ACFB) combustion of coal. The mathematical model has a zone structure, multi-species...

Emissions of the atmospheric pollutants SO2, H2S, CO2, NO, etc. from coal-fired PCC boilers and desulphurization of flue-gas by direct sorbent injection into the furnace are considered. The mathematical model used is based on equilibrium calculations for the coal/water/limestone/air system (50...
