Description

Patent No. 7148 describes a shaft kiln for burning fatty clays, in which vertical channels are made to dry raw polluted clay to dry raw clay to cool the hotplate.

In the proposed modification of the indicated shaft furnace, with the purpose of transferring more heat to increase the prog and to dry the raw clay loaded, in addition to supplying air to the furnace from the cooling zone, the hotter part of the furnace is connected to the same vertical channels .

In FIG. 1 shows a sectional view of a modified shaft furnace and FIG. 2 is a diagram of the direction of hot air and gases in the furnace.

In the case of special humidity of clay or in winter, when it may be insufficient to supply heat to the grimmer, it may be observed that condensation of vapors occurs at a load of about H high.

exhaust pipe. To eliminate this, in the proposed furnace change, in the sintering zone, windows D are arranged through which the hot combustion products can be directed into the vertical channels B, bringing hot air from the cooling zone through the windows. The amount of hot gases sent to the channels 5 can be controlled by the valve if.

The subject of the patent.

The modification of the shaft furnace for burning fat clays, described in patent No. 7148, is different from teM, that besides windows B, which serve for suction, there are also a number of windows L in the hotter part of the furnace, connected to the same rising channels B, with the aim of transferring to the upper part of the mine a large amount of heat and to increase the intensity of preheating and drying of freshly loaded clay.
