✦ Synopsis

Measurements have been made of the surface reaction rates of char particles of 6.3 to lOmm size in a tubular furnace in the temperature range of 600 to 1340K. The char particles were prepared from Prince coal, Nova Scotia, Canada, in a furnace operated as a turbulent fluidized bed at 1123 K. Separate Arrhenius type equations were fitted to describe the reaction rate coefficients for particle temperatures below and above 1000 K. The apparent reaction order was determined as 0.8 and 0.6, for 7" < 1000 K and Tp > 1000 K, respectively. For the convenience of calculation, equations for apparent reaction orders of 0.5 and 1.0 are also given without introducing any significant error.

The combustion rates of three different sized fractions of char from a swelling bituminous coal have been measured in the temperature range 800 to 1700 K. The mass-median sizes of the fractions were 70, 35 and 18 pm. For each fraction the combustion rate was less than the limiting rate set by diffus
