Abstract

The invention makes it possible to increase the life of the boiler by reducing the thermal non-uniformity and ensuring self-cleaning of the pipes. The combustion chamber 2 is limited by the end panel 1 and has windows 3 for the exit of flue gases located oppositely on opposite sections of the tubular walls 4 in the zone of panel 1. Panel 1 is mounted on axis 5 with the possibility of limited movement for alternating from the opening of windows 3 to exit furnace Gases Windows 3 m. are made in the form of festoon. Periodically. by turning the panel 1, the gases are switched to the opposite direction than. self-cleaning of the surfaces of the heat exchange pipes and the redistribution of their load, 1 hp, f-ly, 2 sludge is provided. i SL

fie.g

The invention relates to a power system and can be used in water tube boilers.

The aim of the invention is to increase the resource by reducing thermal irregularity and ensuring self-cleaning of pipes.

Fig, 1 shows a steam boiler; FIG. 2 is a section A-A in FIG. one,

The steam boiler contains a limited combustion chamber 1 with a faceplate 1 of the combustion chamber 2 with windows 3 for the flue gases located oppositely on opposite sections of the tubular walls 4 in the zone of the panel 1, the gyrus ice is provided with a pivot axis 5 and is installed with limited movement around the axis 5 for alternately opening windows 3 for flue gases exit o In addition, windows 3 for flue gases exit can be made in the form of festoons. The steam boiler also contains an embrasure 6 dp of a mount device (not shown), a flue 7 to exit the flue gases from the boiler, a sealing rib 8. The panel 1 is rotated around axis 5 with the aid of a rocker arm 9. The steam to the part of the boiler may include a natural circulation circuit , consisting of upper and lower drums 10, П, connected by heat exchanging tubes 12, forming a convective-Hbrff beam.

Steam boiler works as follows.

In the position of the end panel 1 (figure 2), the flow of gases from the combustion chamber 2 through the window 3, made in the form of a festoon, enters the convective bundle from the pipes 12 and enters the flue 7 through the oppositely located window 3, As the tail pipes 12 are convective The beam (usually once a month) is used to switch the gas flow by rotating the end panel 1 °. In this case, the gas flow is reversed. The self-cleaning of the surfaces of the pipes 12 occurs, the redistribution of the load of the pipes 12 the manipulation of the rotary face panel 1 of the rocker is carried out by the rocker 9 a
