Description

IMPERIAL

PATENT OFFICE.

The hot air rising upwards from the fully flaming chamber is conducted to the two heat conductors H by means of pipe R. Each chamber has four such receiving tubes R, which are connected to the heat conductor H by short shafts and can be closed off by iron bells at χ as required.

This arrangement makes it possible to preheat any other chambers of the furnace (with the intervening ones closed by means of the bells x); On the opposite side, the iron slides E shut off the heat conductors H elsewhere. In the chamber to be preheated, the bells χ are drawn, and the gas flowing out from the heat-emitting chamber, these and possibly also, is forced by the draft of the food at the bottom of the furnace still to pull through the following chambers for preheating or drying of stored materials.

The hot gases can be forced to flow through several chambers, since the .bezw. the ducts A leading to the forge can be regulated in the same way (by bells).

For uniform smoke and smoke evacuation, individual, rust-like closed smoke ducts S are arranged under the furnace base, instead of the larger suction holes previously used.

The channels are covered by means of a rolling layer, with two adjacent bricks each leave a gap of 5 mm. If the move turns out to be too important, it can go through Clogging of individual interstices, regulation can easily be brought about.

The further construction of the furnace, the type of furnace and the operation are the same Ring ovens otherwise used.

The innovations described can be easily applied to existing ring furnaces attach.

Claims (2)

Patent claims: On ring kilns for burning bricks, lime etc .: 1. The receiving tubes R rising from the combustion chamber, combined with short shafts, which enable communication with the heating channel H to be established, and with bells x, by means of which that communication is established and interrupted as required, for the purpose of rational preheating of the chambers or. Regulation of the heating channels. 2. The lying below the furnace bottom, grate-like covered Schmauchkanäle S behufs producing a gleichmäfsigen Schmauch- and smoke exhaustion. For this purpose I sheet drawings.
