Suggested Minimum Combustion Chamber Dimensions
Suggested Minimum Combustion Chamber Dimensions are
based on the rated capacity of the burner.

Figure 2-7: V Burner Installation, Commercial Watertube Boiler
While these dimensions are typical for good practice,
satisfactory results may be achieved with modifications to
suit some conditions. Factors such as fuel properties, total
combustion volume, length of flame trave often make fixed
requirements impractical. When in doubt, consult the factory.
Insulation should be provided between the refractory and the
boiler base. Mineral wool, or other material not likely to settle
is preferred. The chamber front wall may be constructed of
firebrick or insulating firebrick. Insulation should be used
between refractory and front plate. Firebrick, or insulating
firebrick should be set in high temperature bonding mortar
with provision for expansion.
! DANGER
THE GASKET MUST BE RESILIENT TO SEAL
ANY UNEVEN AREAS BETWEEN THE BURNER
FLANGE AND THE BOILER FRONT PLATE TO
PREVENT LEAKAGE OF COMBUSTION GASSES.
