β¦ Synopsis
The design and deveIopment of combustion equipment is still based to 8 large extent an empirical data and modelling techniques. Progress is slow because of the tendency to "play safe.," by ad&ring to designs which have proved satisfactory in the past, especiafly if, as is most often the case, improvements can be determined only by the building of costly models and prototypes.
Computational techniques are, however, now available for the prediction uf turbulent reacting flows in furnaces of abitrary geometry [ 1,21. These procedures contain physical modeis fox the turbulence and the chemical. reaction which require to be verified by comparing predictions with experimental data. The programme of validation work requires to be carefully organized, embracing a wide range of flows in order that all components of the physical mo&liing can be adequately tested* Very few expariments have been performed on combustion chamber!; for conditions which are simple enough to allow assessment of some of the more fundamente? elements of a prediction procedure in at leastpartial isolation.

Burning rates of carbon spheres are measured in a 102 mm diameter bed fluidized in the turbulent regime. Results suggest carbon burns much faster than in a bubbling fluidized bed operating under otherwise similar conditions-excepting velocity. The enhanced burning rate is attributed to high mass tra
