California State University, Fullerton, USA
In brief. Exhaust from a Mercury 50 turbine gives 56 % of the campus cooling, and 44 % comes from gas firing in two Thermax chillers with a total of about 9,200 kW.
The university campus in Fullerton gets about half of its electricity from its own gas turbine. The exhaust goes to two Thermax double-absorber absorption chillers. According to the case, 56 % of the cooling comes from the exhaust, and the chillers make up the remaining 44 % by burning gas directly.
What does the project consist of?
| Parameter | Value |
|---|---|
| Industry | University, campus |
| Engines | Mercury 50 gas turbine, one unit |
| Fuel | Natural gas |
| Heat for the chiller | Exhaust at 375 °C; direct gas firing in the chiller is possible |
| Chillers and cooling | 2 exhaust-fired double-absorber chillers of 1,310 TR each, 2,620 TR in total (about 9,200 kW) |
| What the cooling is for | Campus cooling and heating, hot water |
Why is this example useful for a Russian site?
56 % of the cooling from exhaust and 44 % from gas firing means the chiller is calculated as two sources. The exhaust covers the base load almost for free, while the burner share needs its own gas limit, and that cooling is no longer waste heat: its cost is calculated separately. More: trigeneration with gas turbines.
How does this kind of scheme work?
Gas turbine exhaust goes to an exhaust-fired chiller; when cooling demand is low, the gas goes to the bypass.
