Description

The subject of the invention is a water pipe of a drumless steam boiler with horizontal or vertical arrangement of boilers and natural circulation, characterized by the fact that steam and water separators perform the functions of a drum.

The peculiarity of the proposed boiler is that it uses a battery of highly efficient centrifugal separators of small diameter, which at a high ratio of tangential 1UH in the rate of steam-water mixture to the axial reliable separation of steam from water. The battery of separators is connected with pipes to a system of horizontal collectors in order to preserve the required volume of water in the boiler to prevent significant level fluctuations and surges during unsteady operating conditions. The boiler uses separation collectors connected with a system of lower non-drain pipes with water spaces of separators and a system of upper pipes with steam spaces of separators to reduce the water content of the mixture entering the upper part of the separators and directing the circulating water directly into the water volume of the separators.

FIG. 1 shows a diagram of a drumless boiler; pas figs. 2- part of a boiler with a centrifugal separator battery, a section along I-I pa of FIG. 3; in fig. 3 is the same in cross section, but II-II pas of FIG. 2

In a vertical water-circulation boiler with natural circulation, the drum is replaced by a battery of vertical centrifugal separators 1 made of solid pipes of small diameter, of a usual assortment. Steam removal from the separators is carried out through pipes 2 directly into the superheater 3, without the use of steam-drying devices.

Such batt;) c from centrifugal cent11a) atoms allows, when the ratio is high, tangentially; the entry speed of the steam-to-axial mixture to the axial one ensures efficient separation of steam from water.

The connection of all downhole circulation pipes 4 of the boiler was carried out in the lower part of the separators. To prevent significant fluctuations in the level and surges of water in case of unsteady boiler operation, a system of horizontal co. 1. collectors was applied. made of pipes, connecting with x1 using pipes 6 with separators. To reduce the water content entering the top of the separators and directing the circulating water directly into it. This is the volume of the separators, in the boiler I1) there are the separation manifolds 7, which are also connected from the pipes by a system of lower bypass tubs 8 from the water by the separator volumes and the system of upper T) killed 8th. The surface of the boiler is made of a conventional convective bundle of pipes 10 and furnace screens 11.
