Description

Patent No. 1219 describes a furnace, the upper part of which consists of a common chamber, without wells and revolutions. In order to uniformly heat all parts of the furnace and prevent cracks from spreading in the external walls of the furnace, the heated parts of the furnace in the cavity the brick fireworks or behind it are installed brick pillars that are not connected with the walls of the furnace and are either completely separate or connected only to each other, and they are arranged in the walls of the firebox

openings for the passage of parts of the dimo, exhaust gases by the shortest path to the chimney ..-.

In FIG. 1 113 depicts a vertical section through the furnace of 1-1 in FIG. four; FIG. 2 the same, indicating the movement of the gas stove after the firebox; FIG. 3 is a vertical section through 3-3 of FIG. four; FIG. 4 is a horizontal section through 4-4 of FIG. 3; FIG. 5 is a vertical section of 5-5 N, and FIG. b; FIG. b-horizontal section along 6-b in fig. five; FIG. 7-- vertical section 7-7 in FIG. eight; FIG. 8-horizontal section through 8-8

la - fig. 7

The outer walls of the proposed furnace: room heating is a chamber in which the furnace is not connected with the external masonry, but to increase the internal surface both on the furnace and in the rest of the free cavity of the furnace chamber, p dJT lamps are installed. in the form of walls 1 (Figs. 1, 2, 3,). In the side walls of the furnace, holes 2 are arranged to pass a part of the walls. gases by the shortest route to the pipe and during fuel combustion, the gases move as indicated by arrows in fig. 1. When the furnace is out and the viewer is closed, then, due to the fact that the internal surfaces of the furnace are more heated than the external walls of the furnace, air is circulated in the furnace chamber along the arrows in FIG. 2 During this circulation, the heat from the internal surfaces of the furnace is transferred to the lower parts of the furnace, whereby the heating of the furnace in height is made the same.

In furnaces with a large height (Fig. 7), in order to force all the air to take part in the circulation along the entire height of the furnace, a number of vertical channels are arranged above the furnace.

each having its own hilly 4. Thanks to this device, heat does not accumulate under the Body, but through circulation it is transferred to the lower parts of the furnace walls, which also make the cells thinner than the upper ones, and heating the furnace in height also makes it the same. Internal masonry, which is not connected with external masonry, allows free expansion and the spreading of the masonry from heating, which prevents the occurrence of cracks.

The holes 2 in the walls of the furnace allow a part of the gases to branch directly into the smoke pipe and, by changing the size of these holes, regulate the temperature of the smoke in the smoke pipe. Through these openings, when cold air breaks through into the furnace, it, as more heavy, does not rise higher,

and it is removed directly into the chimney, the heated furnace and the upper parts of the chamber. . ,,.

P redmet patent.

Modification of the room furnace described in patent No. 1219, characterized in that in the cavity of the furnace, the suprasplitter or also behind it, brick columns 1 are arranged that are not connected with the furnace walls and are either completely separate or connected only between dogs. In the latter case, channels 3 are formed, and holes 2 are arranged in the walls of the firebox for passage of a part of the drainage pelvis the shortest way to the chimney. .
