This is what they use a power plants to clean and wash down the fly ash so we can get in there and tig weld new tubes in or stick weld cracks and smaller holes.
I asked one day and the guy said he thinks they put out 50 gpm and 5000 psi. He was just a worker though so not sure. I do know they feed them with 2" hose from a water supply that supplies the boiler tubes with water. Those supply pipes are 12 feet so they definitely have plenty of gpm…lol That might just be to get to the 10th story though. I think they go down to 1" or 1.5" from there to their wand. The 2" line hooks into a 30 gallon pig and then go down in size to hook to the gun.
