SECTION 15561A
CENTRAL STEAM GENERATING SYSTEM - COMBINATION GAS AND OIL FIRED
10/04
**************************************************************************
NOTE: This guide specification covers the
requirements for steam generation plants based on
operating pressure above 200 kPa (30 psig) to a
maximum of 1030 kPa (150 psig).
Comments and suggestions on this guide specification
are welcome and should be directed to the technical
proponent of the specification. A listing of
technical proponents, including their organization
designation and telephone number, is on the Internet.
Recommended changes to a UFGS should be submitted as
a Criteria Change Request (CCR).
Use of electronic communication is encouraged.
Brackets are used in the text to indicate designer
choices or locations where text must be supplied by
the designer.

PART 1
GENERAL
**************************************************************************
NOTE: Sustainable design factors which should be
considered during design of steam generating systems
include, but are not limited to, the following: use
of cleaner burning fuels (natural gas, low sulfur
No. 2 oil); design for minimal air emissions;
specification of boilers and ancillary equipment in
the upper 25% of available efficiency for the
capacity range used; proper insulation of piping,
fittings, and other heated surfaces; returning
condensate to the steam plant for reuse; blowdown
heat recovery; appropriate use of water treatment
systems and chemicals; use of electric rather than
steam turbine motor drives; recycling of dismantled
or demolished material and equipment; and for new
