This paper reports measurements of velocities, temperatures, emission and particle size in two models of pulverised coal furnaces, the one combusting and the other isothermal. In the combusting flow of pulverised coal burnt in a swirlstabilised gas flame, the ability of novel optical instrumentation to measure simultaneously, with high temporal and spatial resolution, coal particle size, temperature and velocity vector using the shadow Doppler velocimeter and a two colour pyrometer is demonstrated. In the isothermal flow, CCD-based instrumentation is applied to measure the long-term Lagrangian dispersion of individual particles in a turbulent, recirculating particle-laden water analogue of the combusting flow downstream of a sudden step expansion.
