Description

The present invention relates to oil chamber furnaces for heating products, KW THAT: steam locomotive bushings, ring spools, etc., during their thermal treatment. The proposed furnace differs from the furnaces known so far by the fact that the combustion chamber, located under the heating chamber bottom, is provided with a divider and through sections is connected to the heating chamber, from which gases fall off into the lower chamber to preheat the combustion chamber floor.

In FIG. 1 shows a vertical section through a furnace; FIG. 2, 3, 4 and 5 - cuts, respectively /1./, / ZI-Ya / and IV-IV t

FIG. one.

The furnace consists of four chambers. An oil tank is supplied to the preparatory chamber L from the oil tank and the air pipe from the fan; from here the prepared mixture of oil and air enters the combustion chamber 5, where the flame strikes the divider 1. goes to the side sections 3 formed by the ribs 5 and, lifting along channels 4, passes into the heating chamber C.

From chamber C, the gases are directed through channels 5 down into chamber D, heating under the combustion chambers, and then from chamber D along two vertical channels, they rise upwards, heating the back wall of chamber C, are directed into the middle unifying channel and then exit under the umbrella, and from there along the diverting pipe to the atmosphere.

Subject invention

Oil for a cementation furnace with a combustion chamber located under the bottom of the heating chamber, characterized in that the combustion chamber B is equipped with a divider / and ribs .2, forming part of the channels connected by 4 ° channels at the side walls. the heating chamber C, for the exit of gases from KOPOpoii, are channels 5 connected to the lower chamber D, which serves to preheat the hearth of the combustion chamber B.
