Abstract When air is introduced horizontally into the packed bed of carbonaceous particles, a heterogeneous combustion zone forms within the packed bed. Depending on the relative gas velocity at the point of introduction of the gas and the size of the packed-bed particles, these combustion zones vary from relatively quiescent regions to zones in which turbulent, high speed, rotational motion of the particles occurs. It is shown in this review that in the past studies in this field have mostly been carried out as a result of investigations into the iron-making blast furnace. In the conducting of this research, four approaches to the problem have been adopted, these being: 1. (i) experiments on laboratory models at room temperature, 2. (ii) experiments on hot models in which the combustion occurs at high temperatures but where a small scale of operation applies, 3. (iii) experiments on full-scale packed beds during or after commercial operation and 4. (iv) theoretical studies which simulate the system. Taken as a whole, the work has shown that the shape, size and combustion characteristics of packed-bed turbulent combustion zones are complex and depend on the physical and chemical nature of the carbonaceous particles which comprise the packed bed and the properties of the injected oxidising gas and any supplementary fuels employed in the process.
