Furnace sorbent injection (FSI) is used to remove SO 2 formed during coal combustion by injecting sorbent into the high temperature zone of a furnace above the fireball. FSI is cost effective for older coal-fired boilers, especially when space or cap

The Random Pore Model developed by Bhatia et al. was applied to intra-particle gasification reactivity of carbon with carbon dioxide in present contribution. Instead of the conventional n-th order equation, the Langmuir-Hinshelwood equation, which tr

Thermal analysis on two coals (semi-anthracite and high-volatile coking coal), iron ore, and their corresponding mixtures was performed using a computer-aided thermal analysis technique. Samples were heated to 1000 °C at a typical rate of 10 °C/min

A mathematical model for the swelling of a coal and the formation of a char structure during devolatilization is developed, based on a simplified multibubble mechanism. The formation of a char has been considered as having two successive steps: a mul

A model for a pressurised entrained flow coal gasifier is presented, with the effect of pressure, reaction kinetics and char structure on the gasification reactions being outlined. A sensitivity analysis to reaction kinetics and char structure was pe

A one-dimensional heat transfer method was used to determine the thermal conductivity for a range of coal ash and synthetic ash samples at elevated temperatures. The effect of parameters such as temperature, porosity, and sintering time were investig

Literature data on the gasification of coal chars with CO2 at moderate temperatures and high pressures has been reviewed, the focus being the factors affecting the reactivity. A model has been developed to extrapolate this reactivity data to high-tem

Bituminous chars with a strongly non-uniform porous structure have not been accounted for in existing pore models used to predict reactivity. A new approach has been developed to predict a particle structure parameter used in the random pore model. T

Char fragmentation during pulverized coal combustion was studied using an Australian bituminous coal. The coal was combusted with air in a drop tube furnace at a gas temperature of 1300°C. The char samples were collected at different levels of char
