Abstract

PURPOSE: To prevent the bad influence resulting from remaining slurry, by selecting a heating pipe to be used from plural lines of heating pipes depending upon the flow rate of the slurry so that the heating efficiency is raised, by cleaning out the slurry remaining in the pipe by the purging device of a suspended pipe.
CONSTITUTION: The plural parallel heating pipes 3A and 3B branched from a slurry feed system are passed through the main body 1 of a heating furnace, the devices (e.g., changing valves) 33, 34, 35,... for changing selectively a heating pipe to be used amount plural heating pipes are set, the heating pipe to be used is selected depending upon the flow rate of slurry so that the flow rate of slurry is kept in a proper range. The heating pipe wherein the slurry flow is stopped with the change of the heating pipe used os equipped with the purging device 36 of a suspended pipe for exhausting the liquid or gas in the slurry component forcedly, so that the remaining slurry in the suspended pipe is cleaned out efficiently, and the bad influence resulting from the remaining slurry is prevented.
