Hello everyone,
We have 2 GE combustions turbines supplying a 300MW Toshiba steam turbine (3 pressures, HP:1200-2400, Reheat: 185-380, LP: 40-60)through 2 HRSG's. During normal operations, our gland sealing steam comes from our Cold Reheat maintaining 4 psig at about 700 degrees Farenheit...
We just switched over today (8-25-03)from amine to ammonia (19% diluted down to 5%), I'll let you know how it goes. Our high pressure system pressure varies from 1200 to 2600 pounds depending on the plant load/duct fire.
we have 2 myron L 6P meters in our lab (powerplant: used for boiler chemistry, cooling tower chemistry, cooling tower blowdown/cleanup, and of course boiler makeup). Neither myron agrees with the other on a sample (of course they calibrate beautifully, but they don't read the same on a...
