SU68836A1 - Open hearth for heating bandages - Google Patents

Description

The open hearths used for heating the tires are provided with channels located in the wall of the cylindrical chamber above the heated tires for the removal of combustion products. This arrangement of channels does not provide for the removal of smoke and gases from the hearth due to the insufficient number of holes. In addition, due to the low gas suction rate, dead zones are formed between the holes of the side suction.

According to the invention, a hearth is offered in which, in order to achieve a uniform removal of the combustion products, the channels are divided into separate sections with independent gas ducts communicating with the common flue.

FIG. 1 shows a section of a forge, and FIG. 2 is a section through ABC of FIG. I.

Onboard suction is located around the periphery of the forge. A continuous chain of channels 2 with narrow walls 3 provides suction in height of gases passing by the gap and eliminates the formation of dead zones.

The on-board suction is performed with a certain inclination downward in order to better accept the products of combustion along their movement. In addition, the proposed structure forms a half-arches in the hearth, which improves heat use and reduces heat radiation. All airborne suction channels are divided into separate independent sections, each of them being a mixing chamber, from which the independent gas ducts 4 depart, converging into a common boar 5 of a smoke extractor.

The invention The open-hearth for heating the tires, equipped for the removal of combustion products by channels located above the heated bandage in the wall of the cylindrical chamber, is characterized in that the channels 2 for their removal are divided into separate sections with independent ducts 4, communicating with the common hog 5.
