4.5.2
Length of the blast tube
The length of the blast tube must be selected according to the
indications provided by the manufacturer of the boiler, and in
any case it must be greater than the thickness of the boiler door
complete with its refractory. The available lengths L are those in-
dicated in the table below.
For boilers with front flue passes 13)(Fig. 11) or flame inversion
chambers, a protection in refractory material 11) must be insert-
ed between the boiler refractory 12) and the blast tube 10).
This protection must not compromise the extraction of the blast
tube. See Fig. 11.
For boilers with a water-cooled frontal, a refractory lining is not
necessary 11)-12)(Fig. 11) unless expressly requested by the
boiler manufacturer.
