✦ Synopsis
98/00510
Vortex combustion of solid fuel in boilers with horizontal and vertical cyclone forechambers Korchevoi, Y. P. &erg. Elekrrif 1997, (2). 7-10. (In Russian) Coals containing 35 wt% ash and 10-40 wt% volatiles can be burned in boilers with horizontal and vertical cyclone forechambers with minimum demand for supplemental fuel. Anthracite containing 4-9 wt% volatiles can be burned in these boilers without supplemental fuel.

Burners, Combustion Systems 9810051 i Activation energy for the oxidation of Malaysian coal chars Haji-Sulaiman, M. Z. and Aroua, M. K. .I. Insr. Energy. 1997, 70, (483), 52-56. Thermal gravimetric analysis was used to study the oxidation of two Malaysian coal chars. The Temperature Program Reaction technique, which employed the random pore model of Bhatia & Perlmutter, was used to analyse the weight-loss data. All experiments were conducted within a temperature range of 698-773 K and heating rates of 2-10 K min-' with char samples in the size range 53-75 ,Lm. The random pore model can accurately describe the oxidation of char to yield activation energy. It is similar to that obtained from model free kinetics, provided the structural parameter ~1, which is an input to the model, is taken as an adjustable parameter.
