Definitions
- a furnace according to the invention can also be used for
- the first hollow body is flooded with the discharge gas in such a way that it flows out of the openings of the hollow body during the flooding.
- the discharge gas in such a way that it flows out of the openings of the hollow body during the flooding.
- an outward flow between the parts is also preferred. Ingress of contaminants into the interior of the hollow body can be largely avoided.
- Figure 2 shows a variant of the furnace of Figure 1 as a second exemplary embodiment.
- FIG. 3 shows a further variant of the furnace from FIG. 1 as a third exemplary embodiment.
- FIG. 1 shows a continuous furnace 1 for producing dielectrically impeded flat radiators.
- the continuous furnace 1 comprises a rohrformigen, about 160 times as long as high hollow body 2 (based on the internal clearances), so is not shown to scale. For example, dimensions of 8 m long, 60 cm wide and 5 cm high. This has an opening 3 for introducing discharge vessel parts 4 and 5.
