Description

The invention relates to a power system and can be used in heating boilers mainly of solid fuel.

A heating boiler is known, comprising a combustion chamber with front, rear, side and ceiling screens, each of which is connected with a distributing manifold, and in the first of the screens there is an opening for a fuel hatch bounded from above by a small manifold to which the middle pipes are connected at their lower ends. the front screen, made with a length shorter than the length of the extreme pipes, while the upper ends of the pipes of the front screen are connected to the lower collector of the ceiling screen, located in two Rus, and convective surfaces and heating placed in the downcomer duct.

The disadvantages of this boiler are low efficiency and low efficiency.

An object of the invention is to increase the efficiency and economy of a boiler.

The goal is achieved in that a heating boiler containing a combustion chamber with front, rear, side and ceiling screens, each of which is connected with a distributing manifold, wherein in the first of the screens there is an opening for a fuel supply hatch bounded from above by a small collector to which are connected the lower ends are the middle pipes of the front screen, made with a length shorter than the length of the extreme pipes, while the upper ends of the pipes of the front screen are connected to the lower collector of the ceiling screen, located in two Rus, and the convection ornament the heating surface is placed in the lowering flue, additionally contains a partition installed between the combustion chamber and the lowering flue, while the lower ends of the pipes of the front screen are connected to the distributing manifold, made in the form of an open rectangle located along the perimeter of the combustion chamber in the lower part, convective surfaces made in the form of pipe horizontal sections. In addition, for the heat transfer efficiency in the proposed technical solution, the sections of the horizontal convective beam tubes are displaced relative to each other.

In FIG. 1 shows a sectional view of a heating boiler; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section BB in FIG. 1; in FIG. 4 is a schematic diagram of the connection of boiler screens.

The heating boiler contains a shielded combustion chamber 1 and a lowering gas duct 2, in which a convective beam is arranged in the form of two vertical collectors 3 and 4 connected by sections 5 of horizontal pipes. Sections 5 are of the same type, which makes it possible to unify the convection beam. A distributor is laid along the lower perimeter of the combustion chamber 1

collector 6 front, rear, side and ceiling screens. The separating manifold b is made in the form of an open rectangle, on the open side of which a front screen is connected to it. In the front screen formed by the middle 7 and vertical extreme 8 pipes, window 9 is made under the hatch for supplying solid fuel. The window is formed by a small collector 10 and vertical end pipes 8, which

They are connected to the distributor

6. The middle 7 and vertical extreme pipes 8 are cut into the collector 11 of the lower bed of the ceiling screen. One of the side screens is formed by vertical pipes 12.

5 connected to a manifold 13 and a distributing manifold 6, and the other side screen is formed by vertical pipes 14, which go into horizontal pipes 15, forming the upper rus of the ceiling screen.

0 Vertical pipes 14 of the side screen are connected to the distributing manifold 6, and horizontal pipes 15 of the upper channel of the ceiling screen are connected to the upper manifold 13. The lower Rus of the ceiling screen is formed by horizontal pipes 16, which are a continuation of the vertical pipes 17 forming the rear screen, Pipes 16 the lower half of the ceiling screen is connected to the collector 11, connected by a jumper 18 to the upper collector 13, and the pipes of the rear screen 17 are connected to the distribution manifold 6. The furnace chamber 1 is separated from the lowering gas duct 2 eregorodkoy 19.

5 The boiler operates as follows,

Water enters the boiler through the pipe 20 into the collector 3 of the convective beam and then through the sections 5 of horizontal pipes 21 it is supplied to the collector 4. Pass the convective beam and partially heat, water from the upper part of the collector 4 passes through the pipe 22 to the distributing collector 6 and then comes immediately to four screens; side screen pipes 14, rear pipes 17

5 screens, vertical end pipes 8 of the front screen and into pipes 12 of the other side screen From the pipes 14, water enters the pipes 15 of the ceiling screen and collects in the collector 13. where water comes from the pipes 12 Water from the pipes 17 enters the pipes 16,

collects in the collector 11. Water also comes from the vertical extreme 8 and middle 7 pipes, and the small collector 10 is fed from the nearest vertical pipe 8. The water collected in the collector 11 through the bridge 18 also enters the collector 13. From the collector 13 hot water through the pipe 23 is directed to the consumer.

In order to increase the heat transfer, the sections 5 of the horizontal pipes 21 are offset from one another. As a result, the horizontal pipes 21 are staggered. This makes it possible to create a wave-like flow of gases passing through the convective beam, which contributes to an increase in heat transfer.
