Results are presented for gasification of coal and char by means of air or air‐steam mixtures in fluidised bed reactors of three different volumes. Two sizes of coal feedstock particles, 0.5‐1.0 mm and 1.0‐1.5 mm, and one size of char particles, 0.5‐1.5 mm, were used. The calorific value of generated gas and the carbon conversion are presented as a function of particle residence time. For coal gasification higher carbon conversion has been obtained at the same particle residence time than for char gasification. For the steam gasification, a lower gas heating value of about 4 MJ/m 3 (S.T.P.) was obtained.
