Abstract

This invention relates to a power system. The aim of the invention is to increase the efficiency, reliability and convenience during installation and operation of the heating boiler. The boiler contains a front screen of horizontal pipes, a rear screen formed by vertical pipes, which transfer to the horizontal pipes of the lower floor of the overhead screen. One of the side screens is formed by vertical pipes, and the pipes of the other side screen are transferred to the horizontal pipes of the upper floor of the ceiling screen. In the lowering gas duct there is a convective bundle of horizontal pipes. Water is supplied to the lower collector of the convective beam and discharged to the consumer from the upper collector of the side screen. 3 il.

Description

The invention relates to a power system and can be used in low power boiler houses.

The purpose of the invention is to increase the efficiency, reliability and convenience during installation and operation of the boiler.

FIG. 1 shows a boiler, top view; in fig. 2 - the same, front view; in fig. 3 shows section A-A in FIG. 2

The heating boiler contains a shielded combustion chamber 1 and a lowering flue 2 in which a convective beam of horizontal pipes 3 is placed. The latter are embedded in vertical pipes 4 connected to manifolds 5 and 6. The front screen is formed by horizontal pipes 7 that enter the outer side pipes screens. One of the side screens is formed by vertical pipes 8 connected to manifolds 9 and 10, and the other side screen is formed by vertical pipes 11, which go into horizontal pipes 12, forming the upper deck of the ceiling screen.

The vertical pipes 11 of the side screen are connected to the lower manifold 13,

and the horizontal pipes 12 of the upper floor of the ceiling screen to the upper collector 9 The lower layers of the ceiling screen are formed by horizontal pipes 14. which are a continuation of the vertical pipes 15 forming the rear screen. The pipes 14 of the lower floor of the ceiling screen are connected to a collector 16 connected by a jumper 17 to the upper collector 9, and pipes 15 of the rear screen are connected to the lower collector 18 which is connected to the collectors 10 and 13. The combustion chamber 1 is separated from the lower duct 2 by a partition 19.

Water is fed into the heating boiler through pipe 20 to the lower manifold 6 and then to pipes 4 and 3 of the convective beam, and from the upper collector 5 connected by a jumper 21 to the lower collector 13 to the pipes 11 of the side screen, through the collector 18 to pipes 15 rear screen and collector GO - in the pipe 8 of another side screen.

From the pipes 11, the water enters the pipes 12 of the ceiling screen and is collected in the collector 9, where the water from the pipes 8 flows.

pipes 15 enters pipes 14, collects in a collector 16, and through jumper 17 also flows into a collector 9. From the latter, hot water flows through pipe 22 to the consumer. Pipes 3 of the convective beam, pipes 7 of the front screen and pipes 14 of the lower floor of the ceiling screen can be made with a slight slope.
