Description

The invention relates to sectional central heating boilers having an external fire box. Central heating boiler houses usually, due to the small distance in front of the boiler front (to the walls of the room), do not allow the installation of remote fireboxes.

We offer firebox intended for boilers, for example. Arrow type, located under the boiler and can be arranged either by deepening the firebox, search by raising the boiler, depending on the level of groundwater. Two systems of dual ascending ducts, each located along the sides of the furnace, are used to conduct gases. In each system, one of the gas ducts (internal) is formed by closed sections of the boiler, and the second is by the lining and the external surface of the boiler. Both systems of gas ducts at the top are brought to the upper part of the internal furnace of the boiler. In the operation of the boiler, the gases exit the furnace by two ascending streams along both sides of the boiler and enter the internal furnace of the boiler, used as a lowering duct connected to the hog.

In FIG. 1 shows a view of the boiler from the front, FIG. 2 is a section along L - I in FIG. 3, FIG. 3 shows a section along A - B in FIG. 2, FIG. 4 shows a section along C - D in FIG. 2 and FIG. 5 shows a section along D - E in FIG. 2; FIG. 6 - longitudinal rupture of the boiler.

In the proposed sectional boiler, for example, of the Arrow type, the external furnace 1 is located directly under the boiler encased in the brickwork. On each side of the boiler, there are two systems of ascending ducts: internal - 3, formed by closed sections of the boiler, and external - 2, between the outer surface of the boiler and its lining.

The ducts 3 through the passes formed by the edges of the sections, communicated with the upper part of the internal furnace of the boiler; there, through the openings 7 in the upper part of the sections, gases come from the ducts 2. The upper part 4 of the internal furnace 6 of the boiler serves as a downward duct attached to the flue I1 of the chimney. In order to reduce the path traveled by the gases in the furnace 6, a roof 5 is located. The blowing duct 9 is located next to the furnace and is placed under the grate. In front of the firebox, for convenience of maintenance and cleaning, there is a small compartment at 8.

Experiments have established that the boiler with such a furnace has a very high efficiency, maintenance of the furnace for loading, scrubbing, cleaning proceeds normally, as in boilers without a remote CABLE, the boiler is more economical to intermittent operation, due to increased radiation against remote fireboxes, the boiler fully allows the use of low-grade fuels.

To prevent overheating in the gap of the lower parts of the sections, due to the deposition of sludge, it is necessary to systematically clean and blow the boiler, before which on the return line of the heating system

Shig. one

It is recommended to set up a sneaker. When feeding with cold water, the latter should be supplied to the upper part of the boiler.

The subject matter of the invention is a central heating boiler, for example of the Arrow type, with a remote firebox, characterized in that, in order to reduce the area occupied by the boiler, the fire chamber is located under the boiler and is connected on each side to a system of dual ascending ducts formed by one closed section mi and the second - lining and the outer surface of the boiler and taken out in the upper part “into the internal furnace of the boiler adjacent to the flue.
