Colorado - Big Thompson Project Amendment #002

Generator Air Coolers Revised 22 11 85 - 4

Avenue, Loveland, Colorado. Refer to Section 00 00 30 - Foreword for Site visit details.

Performance Requirements:

1. Generator air coolers shall have sufficient cooling capacity to maintain the temperature of the air entering the generator air housing at 40 degrees C or less under the following conditions:

a. Generator delivering 100 percent rated output of 47.8-MVA.

1) The Government estimates maximum heat loads of approximately 2-percent of the generator nameplate rating.

b. Maximum cooling water supply temperature of 25 degrees C.

c. Cooling water flow rate of 300 gpm for each generator.

1) Cooling water flow rates may vary up to a maximum of 500 gpm;

however, design of new air coolers should minimize flow of cooling water to the greatest extent possible.

d. With 6 air coolers in service per generator.

Existing System General Description:

1. Each of the generator units G1 and G2 have 6 finned tube air-to-water air coolers mounted at equal intervals within the generator air housing on the outside periphery of the stator frame. The following are the approximate dimensions measured from the spare cooler:

a. The exterior dimensions of the air coolers are 66-3/4 inches by 44-3/4 inches by 18-1/4 inches deep. Each air housing opening for the air coolers is 46-1/8 inches by 32-3/8 inches.

b. The tubes are 1.0 inch outside diameter.

c. There are 6 fins per inch. The fins are 1.75 inch diameter.

d. There are approximately 3 rows of 16 tubes and 3 rows of 15 tubes, for a total of 93 tubes.

2. Cooling water from the raw water supply is fed to the air coolers. The environmental air of the generator is passed through the air coolers and is then recirculated. Air is circulated through the air coolers by the generator rotor.

3. Air temperature is controlled by the rate of raw water flow through the air coolers, each air cooler of which is fitted with a throttling valve to equalize the flow through coolers within the generator. Exit air temperature is measured by a bulb type thermometer, one at each air cooler. The air entering the generator is cooled to less than 40 degrees C by the 6 air coolers.

4. The elevation of the air coolers at Flatiron Powerplant is 5471.00 feet.

5. The approximate weight of each empty air cooler is 820 lbs.
