internal chemicals will be connected to the boiler
drum. If steam is used for cooking or
humidification, a separate heat exchanger will be
required due to environmental constraints with the
use of amines. The following items will not be
required for hot water boilers: water softening
system, chemical feed pumps, tanks, injection
assemblies, water meters, water treatment control
panel, and sequence of operation. The chemical shot
