A few weeks after our initial visit to the PNM Reeves Generating Station, we were given an opportunity to visit the natural gas power plant again. This time around, there was a turbine disassmbled and ready to be reinstalled. This gave us the rare opportunity to see a turbine, as normally they are spinning and in use.
Here are some students taking pictures of a new turbine. The fins of the turbine blade are bigger when the steam pressure is lower, and smaller when the steam pressure is higher.
Here is set of thrust bearings for the turbine. They are gigantic.
One of the neat parts of the tour was getting to cross between Unit 1 and Unit 2 on a high catwalk between the two generators. This was not for those who were afraid of heights.
We also got the opportunity to go into the control room. One of the more fascinating pieces (though I did not take a picture of it) was a giant phasing clock- it spun around in response to the phase of the generator. To bring the power plant online, the phase had to line up with the phase of the grid.
We also got to go onto the roof of Unit 2. These next pictures are from the roof- including a steam drum and a few candid shots of the students asking questions and taking pictures.
Touring the plant some more, we got to take a picture by the firebox door:
Overall it was a great trip, and I think we all had a good time, and learned a lot about power generation.
