Test block flow capacity shall be [_____] actual liter per second cubic
feet per minute. Test block static pressure shall be 140 percent of the
static pressure required to withdraw [_____] L/s cfm from the
[economizer][air heater] outlet interface through the FGD system and to
provide [_____] Pa inches WC at the stack inlet plus [_____] Pa inches WC
which is equal to 140 percent of the static pressure required to withdraw
the design flow from the steam generator to the [economizer] [air heater]
outlet. The static pressure requirement shall be based upon normal
operation of the FGD system, except that the fan inlet temperature shall be
assumed to have the value specified in paragraph entitled "Sulfur Dioxide
Removal Performance Guarantees." The design and construction of the fan
shall be capable of withstanding operation at the maximum gas flow and
temperatures which would result, if the spray dryer was not in operation.
Test block capacity and static pressure shall be calculated assuming inlet
gas temperature to be 93 degrees C 200 degrees F.
Design ambient
temperature for lubrication system shall be [_____] degree C degree F to
[_____] degree C degree F. Induced draft fan speed shall not exceed
[_____] rpm.

Sulfur Dioxide Removal Performance Guarantees
**************************************************************************
NOTE: Stoichiometry for dry scrubbing is defined as
the moles of fresh slaked sorbent introduced to the
system divided by the moles theoretically required
for complete reaction with all of the sulfur dioxide
entering the system whether or not it is all
removed. This is opposed to wet scrubbing where
stoichiometry is generally based on moles of sulfur
dioxide removed by the system. Absorbent
stoichiometry directly affects sulfur dioxide
removal in the spray dryer. For example, a reported
stoichiometric ratio of 1.2 for a dry system
achieving 80 percent sulfur dioxide removal would be
equivalent to 1.5 for a wet scrubbing system. The
absorbent stoichiometry may be raised by an increase
in the amount of absorbent fed to the spray dryer. A
higher absorbent stoichiometry enhances removal of
sulfur dioxide.

NOTE: The compensatory damages for exceeding the
guaranteed stoichiometry will be determined on the
basis of $_____ for each 45 g mole CaO/g mole 0.10
lb mole CaO/lb mole sulfur dioxide increase above
the guaranteed stoichiometric ratio. Deduction of
compensatory damages, if any, shall be included in
the processing of the final payment. The
compensatory damages exceeding guarantees power
consumption will be determined on the basis of
$_____ /kW. Deduction of compensatory damages, if
