SU4405A1 - Central heating boiler - Google Patents

Description

In order to obtain an increased heating surface, a central heating boiler is proposed with a device in which both the flue gases and the water in the boiler pass through the knee path.

In FIG. 1 denotes a top view of the device, FIG. 2-section along the line CD, FIG. 3-section along the line AB.

The boiler is autogeneously welded from boiler, except for the squares connecting the upper and lower parts of the boiler, which are riveted. The entire boiler body is represented by two quadrangular boxes, with a semi-cylindrical surface at the top. The lower edges of the boxes along the perimeters are connected by a strip of iron, which serves as the bottom of the gap between the walls where water is located. In the part of the body where the flat part of the boiler passes into a curved surface, the outer box is connected to the upper part with the squares riveted to parts of the boiler and screwed into bolts. The curve of the surface of the outer box at the front end ends with a dry steam pan. Slightly below the squares connecting the upper and lower parts of the outer casing, there are d partitions (Fig. 3), freely inserted between the squares, tightly fitting

to the rear wall of the boiler and not reaching 200 millimeters to the front wall of the boiler. As a result, the water entering the boiler, through the lower pipe a (Fig. 2), runs along the entire boiler and enters the following boiler compartments, which are also separated from the upper part of the boiler by partitions d (Fig. 3), which fit snugly to the front wall the boiler does not reach 200 millimeters to the rear wall of the boiler, as a result of which water flows from the front wall of the boiler to the rear wall and rises to the upper boiler compartment. Upper squares attaching the partition are made seminal, at which the partition is first inserted, and then the angle is fixed on the studs onto which the copper nuts are screwed. Between the walls of the inner box of the boiler there is a free space, open at the bottom, filled with sections a (Fig. 2).

Sections a are flat boxes with a curved surface at the top corresponding to the curve of the inner box of the boiler. The gap between the walls of the sections is 80 millimeters, the height is equal to the height of the inner box of the boiler, and the width is 100 millimeters less than the width of the inner box of the boiler. In the side and top of the section, two nozzles are welded in

t And p (Fig. 3) with screw cuts. Corresponding to these nozzles, there are holes in the inner box of the boiler through which the nozzles pass and are fixed with copper nuts. The section has a septum inside (Fig. 3). From the first compartment of the boiler through the pipe h enters the section, the partition c causes water to flow down the section, after which it goes up and through the pipe / passes to the upper part of the boiler ( Fig. 3).

Sections a are set at a distance of 100 millimeters from one another. The gaps between them serve as chimneys. Between the front wall of the inner box of the boiler and the first link there is a space D1g TOP1SI. At the bottom of this chamber are grate bars. The ash pit is arranged in the masonry of the boiler, which serves as the foundation for the boiler. The boiler can act, being installed only on the foundation, with soot cleaning holes falling between the sections, and also

have side bricking to heat the side surfaces of the boiler.

The subject of the patent.

Central heating boiler made of iron with partial transverse partitions of water heating boxes in the flame tube, characterized in that the longitudinal partitions d, d, in the outer cavity of the boiler, not reaching the front wall of the boiler, and dd not reaching up to its back wall are made of iron sheets, loosely inserted between the shelves of the squares attached to the walls of the boiler, then klk flat boxes forming incomplete “short” transverse partitions in the boiler space and communicating with it The external cavity each, two nozzles / «,«, is provided at the nozzles n obliquely downward with directional sheets with for deviating downward the water entering the box.
