Description

v Ulcers water-tube boilers with three b fabanals, connected to each other | Other curved tubes. .

In the proposed water tube boiler, tubes are substituted with packets, consists of each of two or more rows, and there are separate free sinuses, sufficiently penetrating into them; Gyoka in the examination of the tubes, cleaning their shifts; these same sinuses have their own leveling / flow of gases,, ir (| passing through one package or another), but get all the velocity of gases everywhere when entering into a single pipe. In order to separate the flow, it goes into the feedwater drum, already Barji "To2 circulating in the boiler, in order to better circulate water, and in order to eliminate water dropping to the bottom of the drum, corresponding longitudinal and yo 1 temporary partitions are arranged in the drums. / attached drawing Fig. 1, 2 and 3 .s depict schematically the riverbed pSiSij s boiler in three modifications, arrangement of packages of tubes n of fig. 4J0 b

longitudinal front upper drum.

Offered. the water tube boiler consists of three drums, B, C,; connected to each other by packages of 1, 2, 3, 10, 24, 25 curved tubes (Fig. J-3), between which sinuses 28,29, 12 are formed, employees to equalize the gas velocities in front of the entrance to the next package. Through the windows-6, 6.; . available; Access to the sinuses for inspection, cleaning and changing tubes.

Between packages 24 and 25 is applied. a zigzag partition 12, resting below on the respective pipe bends or fixed to the pipes, and c. the upper part is terminated with chamotted shaped bricks 13. This zigzag partition, 12, as well as the corresponding mashings of the masonry 26, are intended to achieve a partial movement of the gas movement package and equalize the velocity of the gas flow | in the sinuses between the packages. The power supply of the boiler is on the back of the drum 31 behind the partition 5, and the water is colder

It is placed in the bag 25, where it is heated, to the lower drum C, which, along arrow 17, enters normal to arrow 16, which shows the inlet strongly on water or, more correctly, steam-water emulsion; the fresh and heated water, mixed with this emulsion, heats up strongly and releases scum in the lower part of the lower drum, which then, coming out from under the neperopolqcH 15, enters the front strongly heated and evaporating bundle of packages 1, 2, 3. So As in water descending through the tubes of bag 24, steam bubbles can appear, both entrained by the circulation and obtained by heating the tubes of the bag 24 with gases, and since the speed of movement of the steam-water emulsion when leaving the bag 24 to the lower drum according to arrow 16 will separate the steam from emulsion, septum 15, a hole 14 is arranged to remove steam into the draw current of the package 3. Steam from the boiler is collected in the rear upper drum /, where it is supplied from the front drum A by tubes 18 and from where it passes through the suction bowl 23 or directly along the arrow 21 through the superheater 9 and further in direction of arrow 22 it is directed to the place of its consumption. t Prefabricated boxes 20 and 19 superheaters lie on the connecting tubes 18. The gases from the combustion chamber enter in arrow 32, and leave at the top of the economizer or pipe through Okcho in arrow 33. The entire chamber is divided by a partition-11,. reels package 10 tubes overlaps chambered ceiling 34. Windows-7 II 8 serve for changing the coil of superheater 9, evenly missed between rows of tubes of package 10. The power supply of the rear upper drum B is produced either in its water or B steam space; due to the baffle 5 separating the drum part 31 from the circulation cycle, it does not contain steam and water waves, as a result of which water indicators and water glasses placed on this part of the boiler allow convenient and reliable power control. With strong evaporation and large volumes and rates of steam and water outlets from tubes 1, 2, 3 (Fig. 4)

the emulsion is the living force of the mixture streams entering the ba; raban A: the water to the bottoms 36, the middle part of raban A is filled with a steam and water emulsion to form the water level in the drum; some surface 37-38. Therefore, it is common for the tubes 10 at the average hour: a, sts1 of the drum not to be filled with water, and the remaining 10 near the bottoms for the transfer of water part of the tubes 10 is not sufficiently II inhibits circulation. To eliminate this phenomenon, either the sleeves 10 are located along the curve 37-38; (Fig. 5), or partitions 4 (Figs. 1-3) or 35 (Fig. 4) are used; in the presence of the last pairs between each: the two partitions 35 are separated directly upwards by 39 and all living force goes to enhance the circulation of water.

The subject of the patent.

1. A water-tube boiler with three drums connected to each other; curved tubes, characterized by the fact that the tubes are placed with bars 1, 2, 3, and 24, 25 (Figs 1, 2 and 3) ,. each consisting of two or more rows of tubes and separated from each other by wide free sinuses 28, 29, 1.2 (Fig. I, 2) or 28, 12 (Fig. 3), sufficient for human penetration for the purpose of inspecting pipes, cleaning them and changing them, which sinuses also have as their purpose the alignment of the flow of gases through one or another package and obtaining the same everywhere velocity of these gases when entering the next package.

2.B, the boiler described in paragraph 1 is used in the rear upper drum of the longitudinal partition 5 (Figs. 1, 2, 3) to separate the feed water entering the drum from the water already. heated, circulating in the boiler,

3. In the boiler described in paragraph 1, use in the lower drum in order to. circulation, longitudinal partition 15 with a hole, 14 at the top. -g

4.B described in paragraph 1 of the boiler, the use of transverse partitions 4 (Fig. 1) or 35 (Fig. 4) in the front upper drum, blocking: the openings of all tubes connected to this drum, which partitions have Throwing water to the bottom of the drum (Fig. 4). 5. In the boiler described in p. 1, the use of top drums for connecting tubes 10 holes, j located not horizontal p, dan, but on some curve 37-38 (Fig. 5), remove the exposure of these holes water during rapid evaporation.
