Low-temperature oxidation of coal. 3. Modelling spontaneous combustion in coal stockpiles
In the first two papers of this series, a reaction-diffusion model for low-temperature oxidation of coal was developed and used to extract kinetic rate parameters for a Wyoming subbituminous coal. InExpand

Transformations and destruction of nitrogen oxides—NO, NO2 and N2O—in a pulsed corona discharge reactor☆
Abstract There has been an increasing recent research interest in the removal of NO x from combustion gases using electrical discharges, especially pulsed corona discharge reactors. The major issuesExpand

Mixing of homogeneous solids in bubbling fluidized beds: Theoretical modelling and experimental investigation using digital image analysis
An automated non-intrusive image analysis method has been developed for following the course of solids mixing in two-dimensional bubbling fluidized beds. In this investigation, experimental data haveExpand

Low-temperature oxidation of coal. 1. A single-particle reaction-diffusion model
In this paper, the first of a three-part series, a kinetic model for low-temperature oxidation is developed. The formulation, based on a single isothermal particle, permits assessment of the relativeExpand

Steam-drying of coal. Part 1. Modeling the behavior of a single particle
Abstract Steam-drying of coal is an attractive technology that offers, besides reduction of fire and explosion hazards, improved thermal efficiency. In addition, steam-dried coals appear to be lessExpand

The COCO2 product ratio from the combustion of single petroleum coke spheres in an incipiently fluidized bed
The COCO2 product ratios at or near the surface of 9 × 10−3 m petroleum coke spheres burning in incipiently fluidized beds of 1.82 × 10−4, 5.95 × 10−4, and 1.1 × 10−3 m sand particles have beenExpand

Transport phenomena in multi-particle systems—II. Particle-fluid heat and mass transfer
Particle-fluid heat/mass transfer in multi-particle systems is considered. The approach developed extends the model for momentum transfer reported in an earlier paper. Based on a boundary layerExpand
