About: Inside a coal-fired power plant (IPP plant in Delta, Utah)
Steam is not water vapour. Steam becomes water vapour in contact with the atmosphere. But steam itself is an invisible gas. Often when you see environmental programs they always seem to focus on the cooling towers at a coal fired power station due to the amount of water vapour emerging from the top and they point to that as green house gases. Often in the background you have the long thin chimney with a wisp of coal smoke and that's ignored because it isn't impressive like the cooling towers. If those environmentalists were to go into a cooling tower when it was in operation they wouldn't choke but they'd get soaking wet.
, it's not the really the "generator" itself, it's the exciter of the generator.
DC voltage (585V/5363A max) is fed into these brushes and goes into the windings of the rotor, who creates the magnetic field.
Thanks very interesting
this little thing is supposed to generate over 800.000 kw? O.o
Great video Ryan!
Most air pollution is produced by the burning of fossil fuels it needs to stop!
Is the plant always this clean? My power plant is roughly the same age and looks about 50 years older.
I've been through hundreds of industrial facilities over the years, but the coal fired generating stations are still the most interesting and awesome places I've been. In the last one I visited, the boilers were not suspended, but floated in their own feedwater like ships. 116dB in the turbine hall, had to wear earmuffs and earplugs together. Kind of spooky seeing pressure gauges reading 2600psi. They used to look for steam leaks with a broom. The steam was so hot and dry it would set the broom on fire. Hydrogen gas cooled the generators. It took a week for the turbines to cool enough to be worked on. I was standing next to the forced air blower inlet and a red hot chunk of coal fell out at my feet. I moved along....
The boiler is suspended to allow for expansion of the boiler in a downward direction (3:42
). It is a common practice. Steal expands at a rate of 7.3x10^-6 ft per degree, with this increase in size you have to account for that (even though it is not that much ). If it was hard bolted and not allowed to expand it would crack.
Why is it you can't unload frozen train? Conveyor lubrication freezing? Coal chunks get glued together by ice while train is in transit? Too much water gets condensed on coal after conveyor inside plant?
I think they just don't want you in the control room. NERC Cyber Security Standards - Controlled Access Area just means that you have to be escorted into that area by an authorized person at all times and be logged.
While they do treat the coal before being transported to the silos, most pollutants are removed by a scrubber on the back end of a unit.
The main reason the boiler is suspended from the ceiling is to allow for the boiler to grow as it is heated. The bottom of the boiler sits in what's called a neck seal. This keeps a water seal between the bottom of the boiler and the pantleg /SFC as the boiler grows or shrinks.
you are looking into the "dog house" or the exciter room. This is not the generator.
I'm going to assume the control room at 23:57
is for the cooling towers based on the layout.
Just a few notes on your video.
Such a cool video. Honestly wish it was longer!
A couple of clarifications: The generator shown at 14:06
is indeed one of the generators (26kV), but the device shown at 15:43
is the exciter for the generator. The generator (alternator) is contained within the massive round portion of the orange assembly shown at 14:06
. Also, I gloss over the process of burning and cleaning the coal. The coal is pulverized into dust to be ignited, and the actual "cleaning" is done as part of the process of burning it.
Thanks for this, it’s been awesome to see where it begins!
I didn't know you did YouTube vids or I would've been watching them already. Great video!
