This is con-ducted by the aid of charcoal in a sheet-iron case calleda Liebigs combustion-furnace, Fig. 294. The bottom… … of the case is perforated to admit a draught of air, andfrom it rise a number of supports of iron to sustain thecombustion-tube. As the whole length of the tube isnot to be heated at once, a movable screen of sheet-ironhas also to be provided. How is the combustion-furnace constructed ? COMBUSTION…
