6 .1 Heating system design

Selection of the burner type is dependent on the fur-
nace temperature.
Recommended
Burner
range of use
[°C]
ECOMAX..C up to 1250
ECOMAX..M up to 1100
ECOMAX..F up to 1000
Burners ECOMAX..M (sizes 1 to 5) and ECOMAX..F can
be used for furnace temperatures up to the max. appli-
cation temperature if it is ensured that the burner head
cannot overheat, e.g. due to burners positioned oppo-
site the ECOMAX or non representative temperature
measurements, see also page 37 (Furnace tempera-
ture measurement).
Selection of the burner size is dependent on the net
heat output. From this, the required burner capacity is
calculated using the firing efficiency value.
