WATER-HEATING TANK Russian patent published in 2005 - IPC

FIELD: power engineering.

SUBSTANCE: device has furnace, after-burn hollow, screen and convection bunches of water-heating pipes. Water cylindrical space between sides of furnace is separated by two diametrically opposite walls on two separated semi-cylindrical water hollows. Special piece is connected to lower bottom of furnace in axial-symmetrical way and made in form truncated cone. Burners are mounted tangentially at side surface of furnace close to its upper bottom with direction of axes of burners touching the circle, diameter of which is twice lesser than inner diameter of furnace. Water hollow of after-burn chamber is connected to semi-cylindrical water hollow adjacent to it from lower portion. Furnace through outlet port placed on its side surface in lower portion is connected to after-burn chamber, connected to convective gas line. Convective gas line is formed on inner side of outer cylindrical side of furnace, and on outer sides - by bottoms of respectively upper and lower ring-shaped water collectors and outer semi-side of gas line, mounted in high-temperature zone of gas line close to after-burn chamber outside with additional water hollow, connected to water hollow of after-burn chamber and limited by its bottoms and outer wall. Inside the convective gas line rows of vertical water-heating convective pipes are mounted, connected to upper and lower ring-shaped water collectors. Flow branch-pipe connects inlet of heated water in lower ring-shaped water collector to output of it from semi-cylindrical water hollow.

EFFECT: higher reliability.
