6 .7 Radiant tubes
For indirect heating, different combinations of radiant tubes
and ECOMAX burners can be used.
The metallic burners Ecomax M or FTR are used in metallic
radiant tubes (single-ended radiant tube, P radiant tube or
twin P radiant tube). The ceramic burners Ecomax C are used
in ceramic single-ended radiant tubes, see page 6 (ECOMAX®
in radiant tubes).
Depending on the geometry, flue gas guide tubes may be
needed for radiant tubes and additional adapter flanges may
be required for the metallic single-ended radiant tube.
In special cases, a ceramic burner Ecomax C can be installed
in a metallic radiant tube. Special flue gas guide tubes are
needed here in order to avoid damage to the ceramic burner
due to deformation of the metallic tube.
6 .7 .1 Ceramic radiant tube SER-C for indirect heating
Install the radiant tube free of mechanical stress.
Ensure that there are threaded bolts on the furnace flange to
attach the ceramic radiant tube to the furnace.
Ensure that there is an annular gap of ≥ 20 mm between the
radiant tube and the furnace lining. The flange thickness
P1
of the radiant tube SER-C is either 32 or 37 mm, depending
on the size.
Plan the height of the furnace extension so that the front
edge of the recuperator is flush with the interior furnace wall
(
S1
= 0
±
20 mm).
Loosely wrap a Cerablanket mat or similar material around
the radiant tube before installing it in the furnace.
