spray absorber shall be calculated from the lime slurry feed rate and the
calcium hydroxide content of the lime slurry as determined by ASTM C 25.
Conduct separate tests for each spray absorber. Tests shall be performed
at both 50 and 100 percent of rated boiler capacity. Contractor shall
consult with the Contracting Officer and with the Government's operators to
coordinate schedules and operating conditions for the tests.
3.4.6
System Power Consumption Tests
Contractor shall measure the total power consumption of the flue gas
cleaning system with boiler unit in operation at 100 percent of rated
capacity. Power consumption shall be determined through the use of
watt-hour meters provided by the Contractor for the purpose. Watt-hour
meters shall be used at the power supply inputs to the motor control center
for the lime slurry preparation equipment, the motor control center for the
spray absorber-baghouse combination in operation, and the operating induced
draft fan motor. The watt-hour meters used shall be accurate to within 1.0
percent. Coordinate test schedule and operating requirements with the
Contracting Officer and the Government's operators.
3.4.7
Test Failures
In case any of the equipment furnished under this contract fails to operate
as required, or in case of failure to meet any of the provided for in this
contract, the Government shall have the right to operate the equipment
until such defects have been remedied, and guarantees complied with as
specified in paragraph entitled "Quality Assurance," without cost to the
Government. Failure to meet guarantees for which a schedule of
compensatory damages has been specified may be resolved, at the
Government's Option, by deduction of compensatory damages from the final
payment. Removal of rejected equipment shall be scheduled at the
convenience and discretion of the Government. In the event that serious
defects necessitate the rejection of equipment, the Government will have
the right to operate the equipment until such time as new equipment is
provided to replace the rejected equipment.
3.5
PAINTING
Provide field painting of those surfaces of the following equipment not in
contact with the flue gas stream; cyclones, fabric filter baghouse, fans,
dry scrubber, and ductwork. Field painting shall meet the requirements
specified in Section 09900 PAINTS AND COATINGS. Other equipment provided
in this section shall be painted; either field-painted with systems
conforming to the requirements specified in Section 09900 PAINTS AND
COATINGS or painted with factory or shop painting systems conforming to the
requirements specified in Section 15050N BASIC MECHANICAL MATERIALS AND
METHODS.
3.5.1
Galvanic Corrosion Prevention
To prevent galvanic corrosion, care shall be used to prevent permanent
contact of aluminum casing with copper, copper alloy, tin, lead, nickel
alloy including Monel Metal. Where it is necessary to attach the casing to
carbon steel or low alloy steel, the steel shall first be prime painted
with zinc chromate, and then painted with aluminum paint suitable for
surface temperatures encountered. The use of lead base paint is not
acceptable.
