Description

(54) K-TYPE WITH P-SHAPED LAYOUT

I

The invention relates to a power system and can be used and boiler arpe-f gatah.

The closest to the proposed invention is a boiler with a P-shaped arrangement containing a convective gas duct connected to the tray, part of the rear screen of which forms suspension tubes with its upper sections, and the other part is bent out of the screen plane with the formation of a festoon and a gas-tight ceiling screen of the turning chamber one.

The disadvantage of the boiler is its low efficiency due to the metal intensity and laboriousness of its manufacture.

The purpose of the invention is to increase efficiency.

This goal is achieved by the fact that the bent sections of the screen tubes are inserted into a convective flue for placement in the last festoon and with the formation of gas-dense bottom and ceiling screens, respectively, of a turning chamber and a convective flue.

FIG. 1 shows the upper part of the boiler, a longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - section G-G on fng. one.

The boiler contains suspended from the frame 1 suspension 2 firebox 3 and the convective duct 4, connecting each other with a rotating chamber 5.

ten

Part of the pipes of the rear screen 6 of the furnace 3 forms suspended pipes 7, and the other part is bent and turned into a convective flue 4, where it forms a festoon 8 and a gas-tight ceiling screen 9. A part of the pipes is bent

15 of the screen 6 also forms a gas-tight hearth and ceiling screens 10 and 11 of the turning chamber 5 and is connected, as well as the hanging pipes 7, to the collector 12.

Front screen 13 of the firebox 3 is connected

20 to the collector 14, and the front screen 15 and the rear screen 16 of the convective gas flow 4 are connected, respectively, to the collectors 17 and 18.

In the rotating camera 5, the front screen 15 forms a festoon 19.

The organization of the passage of the bent part of the tubes of the screen 6 through the front screen 15 is carried out by selecting the diameter of the tubes and their steps so that the tubes of the screen 6 freely pass between the tubes of the screen 15. If necessary, a local crimping of the tubes of the screen 6 can be carried out at the passages on a smaller diameter.

The boiler works as follows. The flue gases generated during combustion in the furnace 3 give some of its heat to the screens and, the passage between the suspension pipes 7, enter the turning chamber 5 and then through the festoons 19 and 8 into the convective gas flue 4, gradually cooling at the same time.

Placing the bent sections of the tubes of the rear screen of the furnace in a convective flue with the formation of a festoon in the latter and a ceiling screen allows you to get rid of the additional supporting frames and supporting

elements, which leads to a decrease in metal consumption and increased efficiency.

Claims (1)

Invention Formula A boiler with a U-shaped layout, containing a rotary chamber connected to a convective flue and a firebox, part of the rear screen tubes of which forms suspension tubes with its upper sections, and another part is bent out of the screen plane with the formation of a scalloping and gastight ceiling screen of the rotary chamber, characterized in that in order to increase the economy, the bent sections of the rear screen tubes are inserted into a convective flue for placement in the last festoon and with the formation of gas-dense floor and ceiling screens with tvetstvenno rotary chamber and the convection duct.
