Sed′i-ment-col-lect′or.
(Steam.) A device to prevent the deposition of sediment on the bottom of boilers. An inverted hollow cone, whose mouth is a little above the water surface of the boiler. It communicates with the rest of the boiler by triangular openings near its upper edge. Scum and temporarily floating crystals of salt and solid matter passing into the comparatively still water of the cone, settle to the bottom, or apex of the cone, and are thence blown off. Scott's (English) patent, 1827, consists of a vessel or series of vessels placed longitudinally of the boiler, and acting as a false bottom to receive the deposit. The water within these remains tranquil, while that outside may be in a state of violent ebullition.
