SU55630A1 - Vertical Hot Water Boiler - Google Patents

Description

It was filed on January 19, 1938 in the NKKHOz RSFSR for the number 603. Published September 30, 1939.

The invention relates to water-heating vertical boilers in the form of a vertical cylindrical drum mounted on a masonry of a combustion device. The bottom of the drum is provided with a box open at the bottom and a cylindrical or other shaped box located inside the drum. The latter is divided by the height of the furnace wall to use the cavity of the box as a flue from the underlying firebox or burner. In order to induce pulling, the firebox may have a connection with the last smoke, or an intermediate smoke.

In a similar proposed boiler, a part of the ducts located inside it is made of flat boxes to increase the heating surface. The boxes are fastened to each other in the water space of the boiler with the help of inclining transverse ribs, used to improve the circulation of water.

The boiler is intended for local water supply of canteens, laundries, baths, bath units, hospitals, etc.

In FIG. 1 shows a vertical section of the boiler in / - / in FIG. four; FIG. 2 - the same for // - / Y in FIG. four; FIG. 3 - the same as /// - I / in FIG. 2; FIG. 4 is a horizontal section of the boiler according to IV-IV in FIG. 2; FIG. 5, however, according to FIG. 2; FIG. 6 is a detail of fastening the drum K (rthla; Fig. 7 is a diagram of installation of a boiler with a hot-water tank; Fig. 8 is a diagram of installation of a boiler connected to a water mains; Fig. 9 is a modification of the mounting of the drum cover.

The boiler is a cylindrical drum of thin sheet iron, to which the corners 2 are welded at the ends - the upper one for rigidity of the drum, and the lower one for attaching the bottom 3. Inside the drum are several open bottom, parallel to each other, boxes 4-5. Each box has an incomplete vertical partition 6 (Fig. 2i, dividing the box into part 4 for the upward flow of gases from the underlying firebox and part 5 for the downward flow. The partition can be protected from asbestos sheet burnout. Boxes 4-5

the lower edges are welded to the bottom 3 of the boiler, which is attached to the lower corner (rim) 2 of the drum / using bolts on an asbestos pad 7.

The boxes 4-5 are provided with laterally welded ribs 9, at an angle of about 45 °, designed to ensure proper circulation of water around the boxes.

The upper part of the drum / rises above the boxes 4-5 and forms a receptacle 10 corresponding to a conventional hot water tank for baths mounted above the hot water boiler.

To prevent water from splashing out, the drum / overlaps with a hatch / / hatch / 2 to release steam. In cases where the flow rate of hot water is regulated, for example, for the bathroom departments of hospitals, and creating a supply of hot water is not required, the boiler can be made without container 10 (Fig. 9), and the lid 11, fitted with a fitting for wiring. tube 13, is welded to the cylinder / at a close (10-15 cm) distance from the boxes 4-5, resulting in a compact hot water boiler with a large heating surface. The drum 1 is provided with a separator pipe 13 for withdrawing hot water and a feed pipe 16 with a valve. A pocket 14 is attached to the bottom of the drum / with a drain valve 15 for removing dirt and turbidity deposited in the boiler. The drum / is insulated from the outside by cladding (boards) 17, which is reinforced on the sides of the 18.

The mounted boiler is installed on the firebox divided by a partition 19 on the front part - the firebox 20 and the rear part - a diversion chamber 21 connected by a chimney 22 with a chimney. Between the furnace 20 and the chamber 21 there is a pilot bypass chimney 23, equipped with a gate 24, which blocks the chimney during normal operation of the boiler plant. Chamber 21 is equipped with cleaning 25 to remove precipitated ash. For mobile installations

made of cast iron with brick

lining.

FIG. 7 depicts installation of a boiler, for example, in rural banks, when installing a pressure tank in the attic of a bath in the absence of water supply. The pressure tank is installed so that the water level in the tank and the boiler is the same.

If there is running water or when installing a pressure tank at high altitude, the boiler is mounted according to the diagram in FIG. 8. Water is supplied to the boiler through a conventional feed tank with a float regulator 27 installed at the water level in the boiler. For work, after filling the boiler with water and putting the fuel in the firebox, open the gate 24 and ignite the fuel. When the fuel has burst, gate 24 is closed, and the hot gases pass successively through boxes 4-5 with vigorous stirring and combustion due to a sharp change in the direction of the gas flow. Burning in the firebox is regulated by a blower door. The washing water of the boxes 4-5 during heating cannot rise vertically upwards and is taken away by the fins 9 to the side, giving the opportunity to rise to the walls of the boxes with new portions of cold water, thus accelerating the mixing and heating of the entire mass of water filling the boiler.

The subject invention.

A vertical hot water boiler equipped with a box attached to the bottom and located in the cavity of the drum, separated by a vertical incomplete partition and intended to carry gases from the furnace placed under the boiler, characterized in that part of the ducts located inside the boiler is designed to increase the heating surface flat parallel boxes fastened together in the boiler water space using transverse inclined ribs used to improve the water circulation conditions .
