What information is needed to design air inlet cooling…?
The basic information required to design the air inlet cooling system is: 1. Turbine operating characteristics at base load, ISO conditions of 590 (f) ambient dry bulb and 600 (f) web bulb temperatures. Operating characteristics are: a. Megawatt output b. Heat rate (BTU/KWH) c. Gas cost per million BTU’s d. Treated water cost per gallon (if known) e. Energy value per kilowatt or megawatt. f. Climate data. Climate data note: Total hours available for evaporative cooling in 50 (f) increments is necessary for an accurate prediction of savings to be realized and payback period. ASHRAE design conditions provide a maximum that is exceeded only 1% (or scale used) of the time. Turbine output is inversely affected by temperature. Unless total hours available for cooling are considered, the results will be inaccurate and payback period undependable. Structural & Mechanical considerations: g. Existing air inlet housing structure layout and dimensions of air inlet area. h. Retain existing dry filt
