foundation that can withstand the weight and
absorb vibration is essential.
Reinforced concrete slabs with runners
provide for placing and anchoring the boiler. The
runners should provide a level, uniform support
and be of sufficient height to allow for
maintenance and the installation of piping under
the boiler. A raised platform also provides easier
access for boiler room cleanup.
Generally, a sump in the slab between the
runners provides a catchment area for boiler
blowdown or draining of the boiler. This sump
drains from the building to a suitable dispersal
When considering the requirements of
sheltering a boiler, you must ensure there is
enough room for the boiler and all of the accessory
equipment. This accessory equipment may include
condensate tanks and pumps, chemical feeders,
water makeup tanks and feeders, and blowdown
The boiler room must also be large enough to
allow for boiler maintenance, for retubing, and for
removing and replacing the boiler. The tube
length of a boiler maybe from 2 feet 6 inches to at
least 10 feet, and possibly longer. To simplify the
removal of the tubes, ensure the boiler room is
long enough or have a door located behind the
boiler. The most important thing to check is the
manufacturers specifications, which provides the
proper dimensions for locating the boiler.
Fresh air inlets and louvers allow fresh air to
enter and move across the boiler area. This fresh
air entering the boiler room removes excess heat
and provides adequate makeup air for combustion.
When planning for boiler room construction,
you must always consider boiler requirements,
maintenance requirements, and manufacturers
