Abstract

FIELD: boiler engineering, stationary and mobile boiler plants with various coolants. SUBSTANCE: device has tube bundle built up of external uptake tube with blind bottom and internal downtake tube. Each tube is diametrically split and its parts are joined as follows: in external tube, by annular drilling of bottom; in internal tube, by coupling installed on inner projection of external tube. Bottom of internal tube is connected through threaded joint with mud box joined through drilling with external tube bottom. In heating, steam-water mixture goes up in channel between parts of internal tube 11 and external tube 2, passes through holes 17 of coupling 6 and between parts 10 and 1, then it goes to drum. Steam is separated from water as the latter moves in internal tube and through its holes 13 flows to space between parts 11 and 2 of tubes; mud is discharged to mud box space 18. EFFECT: facilitated maintenance, repair, and manufacture, improved efficiency, reduced fuel consumption. 1 dwg

Usage: boiler building, stationary transport boiler plants with various coolants. Technical result: improving the manufacturability of maintenance, repair and manufacture of the boiler, preventing operational reduction in efficiency and increasing fuel consumption. Essence: a bunch of coaxial pipes from an external lifting with a deaf lower extremity and an internal lowering. Each of the pipes is made in detachable diameters, the parts of which are interfaced: the outer pipe has an annular groove of the tip, and the inner pipe has a sleeve mounted on the inner protrusion of the outer pipe. The lower end of the inner pipe on the thread is connected to a chamber for collecting sludge associated with a groove with the lower end of the outer pipe. When heated, the steam-water mixture rises in the channel between the parts of the inner 11 and outer 2 pipes, passes the holes 17 of the coupling 6 and between the parts 10 and 1 of the pipes and enters the drum. With the separation of steam from it, water moves along the inner pipe and its holes 13 and flows into the cavity between the pipe parts 11 and 2, and the sludge falls into the cavity 18 of the collection chamber. 1 ill.
