Abstract

<PICT:0715167/III/1> In a furnace or reactor for treating solid materials with gases by fluidizing technique, the water jacketed reaction chamber 1 is charged from an opening 9 with coarse particles of 28 mm. grain size forming a fluidized bed over the grate 4 into which bed five particles of 0-1 mm. grain size are then fed from a hopper 7. The coarser particles may be inert or reactive material. The reaction chamber opens out into a wider expansion chamber 2. The invention is applied:-(i) to the roasting of zinc blende in a bed of sintered zinc blende of 2-6 mm. grain size. (ii) to the combustion of coal dust in a bed of glowing sintered carborundum of 4-8 mm. grain size. (iii) to the decomposition of waste sulphuric acid mixed with coal dust in a bed of glowing carborundum. and (iv) to the low temperature carbonization of coal in a bed of ash of 2-6 mm. grain size.
