TlL Fig. 30 represents a furnace for the manufacture ofcarbonate of potash fi*om Tolk, devised by H. Fischer. The concenti^ted jolk solution is first put into thetank a and warmed bv the waste heat of the tank a is situated at a high level and theconcentrated yolk solution is led into the chimney, whereit trickles down in a zig-zag course across OTerlappingsteps at once into the chamber h. The flow can be soregulated that the level of the liquid in 6 is the Iegular course of work the Hquid is run from the. Fig 3*.—5txuerlymanaged the process is almost continuous. Care must betaken in admitting new liquid from h into the red-hotchamber c, since it froths up very considerably. The pipeconnecting h and c is so arranged that it can be readily re-moved and cleaned. Comparatively little coal is required,since it is largely economised through the burning of theoi^ganic matter of the yolk itself. It has been found in Chap.
