5-3.3.1 Gas Burners. All gas-fired equipment will be equipped with a burner, which
can be readily converted to burn an alternate fuel, as required in AR 420-49. Specify
gas equipment for dual-fuel capability.
5-3.3.2 Oil Burners. The selection of oil burners will depend on the grade of the oil
being burned, the size of installation, and the need for modulating control. For light oil,
atomizing will be accomplished using oil pressure, air, or steam atomizing burners. For
heavy oil, atomizing will be accomplished using air or steam atomizing burners.
5-3.3.3 Stacks and Draft Requirements. Heating installations will include either
natural-draft chimneys or individual boiler ventilation fans with stub stacks. Where
natural-draft stacks would be a hazard to aircraft or otherwise objectionable, use
mechanical-draft fans discharging into short stub stacks.
5-3.4
Fuel Selection and System Design. Fuel selection and system design will
be in accordance with the ASHRAE Handbooks, NFPA Standards, UFC 3-600-01 Fire
Protection Engineering for Facilities, and AR 420-49.
5-3.5
Auxiliaries. Boiler plant auxiliaries should, in general, be electrically driven;
however, whenever an uninterrupted supply of steam is essential, provide one of the
boilers with steam-driven auxiliaries. Provide individual forced or induced-draft fans
with each boiler unit. Provide necessary standby equipment to maintain essential
operations.
5-3.6
Flow Measurement. Meter gas, oil steam, and hot water at the central plant
(both supply and return) and at each building served (supply). Meter both the supply
line and the return line of each storage tank.
