DE392736C - Firing for metal u. like baths - Google Patents

Description

The invention relates to a furnace for metal baths and the like. It is known such Furnaces with a provided between the pan wall and masonry, for S to accommodate the solid firing material. . This annulus but has so far been carried out openly at the top, so that the combustion gases in the work area escape and damage the health of the operating team as well as to Reduction of the work performance of these operating teams. On the other hand it is known to use other furnaces with adjustable air supply and air discharge

channels to be provided. The attachment of such air supply and gas discharge channels in the case of furnaces, in which the furnace material is placed in the pan in an annular space surrounds, presented difficulties because of the unfavorable structural conditions of such Furnaces, especially because of the need to keep the walling small, accessible from all sides and the pan as far as possible to avoid towering structures.

The solution to this problem for the said furnaces is achieved according to the invention achieves that the discharge ducts for the combustion gases that enter the top of the Firing material-receiving annular space open through the one surrounding the pan ascending masonry can be led down into the fox. In addition, in a manner known per se, controllable stoking and air supply channels open into the annular space at the bottom and the filling opening of the annular space is made coverable, so that pouring the, firing can take place unhindered, but in the company a trespassing of Combustion gases in the work area is excluded.

A furnace designed in this way is extremely easy to supervise, easy easy to load and cheap to manufacture; it still offers the advantage of being flawless Controllability - and good heat transfer to the bath and thus considerable fuel savings.

The drawing shows, for example, an embodiment of the subject matter of the invention shown. ,

Fig. Ι shows a cross section through masonry and pan,

Fig. 2 shows a longitudinal section through the same according to AB in Fig. 1 and

Fig. 3 shows a longitudinal section according to CD in Fig. I.

The pan ο is surrounded by the masonry k at a certain distance, so that an annular space & is created between the pan and the masonry, into which the fuel is poured through the insertion opening c. The insertion opening can be closed by the cover /.

ίο At the bottom open into the combustion chamber δ the pits d and at the top the exhaust openings e for the combustion gases.

The piercing holes d can be completely or partially covered by covers g.

»5 The gas outlet ducts e are continued in ducts h, which run downwards in the masonry and finally open into the fox and through slides! can be completed in whole or in part.

By means of the slider i and the slider or cover g , both the extraction of the combustion gases and the inflow of fresh air can thus be regulated as desired. .

Accordingly, the burning of the fuel in the furnace b can be properly regulated, so that the occurrence of flashes is prevented. Coke, for example, can serve as fuel. The fuel slowly sinks from top to bottom. The ash, possibly slag, is removed through the potholes.

Claims (1)

Patent claim: Firing for metal and the like.
