actual temperature of a given gas-vapor mixture and the adiabatic
saturation temperature of that gas-vapor mixture.
c.
Spray/Dryer: An apparatus in which flue gas is contacted with a
slurry or solution such that the flue gas is adiabatically
humidified and the slurry or solution is evaporated to apparent
dryness.
d.
Stoichiometry: The moles of slaked sorbent introduced to the
system divided by the moles of sorbent theoretically required for
complete reaction with all of the sulfur dioxide entering the
system whether or not it is all removed.

DESIGN REQUIREMENTS
1.4.1
Detail Drawing
1.4.1.1
Dust Collector System
Submit drawings and diagrams necessary to erect, install, startup, and
place the FGD system into regular operation. Indicate the kind, size,
arrangement, weight of each component, and breakdown for shipment; the
external connections, location of local controls, remote control panels,
anchorages, and support required; the dimensions needed for installation
and correlation with other materials and equipment; and structural steel
and foundations. Submit fabrication details including reinforcing and
embedded items cutouts, holes, welds, and attachments, and identify
components with piece mark numbers. Include the erection, assembly, and
installation sequences, and the tolerances to be maintained in erection,
assembly, and installation.
1.4.1.2
Dust Collector Components
Submit drawings for each component showing design and assembly. Include
the arrangement of internal apparatus and components, and the location of
internal piping, tubing, valves, wireways, busses, and terminal blocks, and
flow diagrams with flow rates, pressures, temperatures, valving, and
instrumentation. Submit drawings for each gage board, instrument rack,
mounting plate, and transmitter bracket showing at least the construction
features, bracing, brackets, device mounting holes, and dimensions required
for fabrication. Submit schematic drawings of processing sensing lines for
each type of installation, instrument, or special case including water
level columns and draft lines. Submit layout drawings of control boards
and system cabinets showing component arrangement. Submit drawings for
each graphic subpanel, to include symbols, flow lines, indicating lights,
switches and other devices. Damper submittals shall indicate information
for the general arrangement and outline, insulation, instrumentation,
erection, electric motors, details of seal air systems, and design flows
and pressures for transmittal to damper manufacturers. For instrument and
control devices, submit outline drawings and listing of tag numbers for
each type of device furnished. One drawing may be used for devices of the
same type, but the drawing shall be marked to list the tag number of
devices to which it applies. Indicate tag numbers on device drawings,
instrument lists, functional diagrams, and logics. Include drawings that
apply to each item listed below.
a.
Spray dryer sulfur dioxide absorbers
