General Notes : 1) Vendor shall provide outstanding data such as performance curves, power of drive, speed etc. for the different cases specified. Performance curves shall be provided for guide vane control. 2) Fan design shall be according to min. API 560. 3) Speed for closing/opening guide vanes to be stated by vendor under following requirements: • Increase the actuator size to the next available manufactured size to meet a short closing time. • Locate the actuator as close as reasonable to the dampers and reduce the clearance of all mechanical links • provide fixed inlet vanes to ensure proper stream lines and avoid vibrations from choking & increase stiffness of the casing • long-term and controllable operation at the given partial load conditions has to be taken care of in the design 4) Fan efficiency shall be 75% or more for the Normal and design case. 5) Corrosion allowance for Carbon and low-alloy steels (other media) = 1.6 mm 6) Cooling water specification for motor to be defined by the Vendor 7) Material of construction shall be confirmed/provided by fan vendor. 8) The cross-section of flue gas duct to be checked during detail engineering to match with the fan discharge duct size. 9) All data have to be checked during detail engineering based on vendor data.
