NGS: The Stages of Demolition

Still Making Megawatts

This undated photo shows all 3 units of Navajo Generating Station online and making megawatts.

Stack Demolition

This view of the 12-18-2020 stack demolition was taken from the 500kV yard on the west side of the power block. The unit 3 precipitators came down as part of the stack implosion. Click to enlarge.

Units 1 and 2 Precipitators

Following the stack implosions, the units 1 and 2 precipitators were next to go. This image shows the units 1 and 2 precips moments before their demolition on 1-19-21. The unit 3 precips came down with the stack implosions on 12-18-2020 and can be seen on the left side of the picture. click to enlarge.

The Stackless Version

I took this picture on March 2nd, 2021, the day before the boiler demolitions. The stacks and precipitators are already gone. The stacks and the unit 3 precips came down on 12-18-20. The units 1 and 2 precips came down on 1-19-2021.

Boiler Demolition

This still image was taken from my video of the boiler demolition on 3-3-21 and shows the units 1-3 (right to left) boilers coming down, along with the unit 3 elevator.

Boiler Demolition Aftermath

After the boiler demolition, this cloud formed over the NGS plant site due to the coal fire that resulted from the demolition. The coal silos for all 3 units were part of the demolition that day and a pretty significant fire ensued but it looked like it was quickly contained. Click image to enlarge.

Turbine Deck and Power Block

I took this in the late afternoon of March 3rd, 2021, the day the boilers came down. It was still hazy from the smoke earlier. Click image to enlarge and you can see a U3 silo and part of the boiler laying on their sides and a couple of the U3 steam leads sticking up in the air.

NGS Precipitator Demolition

On Tuesday, January 19 2021, the Units 1 & 2 precipitators were demolished at Navajo Generating Station. The Unit 3 precips were demolished on December 18 2020, as part of the stack implosion.
