Distilling tar.-Tar stills are provided with circulating-apparatus comprising a false bottom F, a pipe or pipes G, and a number of pipes 0 directing steam jets under the exterior of the false bottom F. The tubes G communicate at their upper ends with one or more chambers H such as that formed between the flange I and the disk J, whereby the upflowing liquid and gases are directed towards the walls of the vessel, this action being aided by means of conical projections L. The chambers H may also be formed with slotted walls, or be wholly or partly replaced by perforations in the upper parts of the tubes G.
