GE repaired the generator rotor they damaged, it came back thru on truck yesterday morning. Should have the unit ready to start in around two weeks should all go well. https://youtu.be/47eiZyK_nUI" rel="nofollow - https://youtu.be/47eiZyK_nUI At the 6:27 mark I drive into the intersection in the dump truck I have been running, was hauling for a local creek bank reinforcing project, got entangled in the road block.

| I heard they were planning on the slow travel route- never heard exactly how heavy it was, thanks for the link , very cool ! |

| 160 ton for the rotor, 215 ton for the entire rig. |

Labadie is a coal fired power plant in Missouri. They have 4 units. I think each is about 600 MW.. Coal furnace produces the steam to spin a STEAM TURBINE that drive the generator. Part of the AMEREN Generation system.. Several Illinois plants were part of this 10 years ago... then Ill was sold off. ------------- Like them all, but love the "B"s. |

| They were all ALLIS CHALMERS turbines at one time -and maybe some still are |

Most of Ameren power station turbines have been changed out. Time with erosive effects of steam and condensing moisture eats them up losing efficiency. Callaways turbines(4) were replaced in 2005, one High pressure of 540degrees at 1000 psi and the three low pressure that reuse reheated exhaust from the HP to drive this rotor as a stack. Labadie turbines were Westinghouse as is Rush Island, Sioux was a oddball built by B&W where not certain who built those two. Meramec station had four but all are individual none built same time or by same company where I believe was one or two Allis. Long gone is Venice which had all Allis turbines. Fusion may become viable in five to ten years. That will pretty well eliminate all the existing stations across the globe. |

Some plants were built in 1930 or 1940 when power was just coming of age.. Might have one Unit that was 50 MW....As demand increased, they built a second, third, fourth unit... Maybe 1940 , 1950 , 1960... etc... In those cases the technology was increasing yearly so the units were drastically different in design and 2-3 times as big ( MW output) every 10 year. Plants like Labadie, Calloway, Newton, Coffeen were a one time / big demand for power - build.... 2-4 units, all basically identical ( for that plant), all built over a 5-6 year time frame.

Sioux and Coffeen are similar units, Super Critical B&W Boilers, use 2500psi Superheated steam. Labadie, Newton, Rush island all standard Westinghouse system design around a standardized fluidized bed boiler, HOWEVER were designed for Hard High Sulphur Coals that burned HOT and less dirty than soft brown coals as the Powder River Basin junk. PRB Coal is more dirt than combustible, takes a third more to make same MW Electric power and the slag development is horrific. Slabs the size of school bus sides precipitate against tube walls and end up having to be steam lanced or explosively detached while boiler is still operating, severe duty on steam tubes. That operation of lancing is what got one tech at Labadie killed. Oddly if look up build times, more often than not the Last two units generally come on line First and lower number units last. Construction starts with units furthest away from Crane pedestal and lay down yard. Callaway is a Single Unit Nuke where plans were for two initial and up to six in total. The unit standing is called Unit One, all the Reactor Building shield tins were marked Callaway Unit Two as I worked there until the new Steam Generators went in.

| Geesh the equipment they have to have in those plants to handle that rotor and generator parts must be something |

Two installed turbine building cranes are De-rated to 220 tons Each, on initial install during construction were rated at 280 ton but de-rated after completion as that was common practice. Reactor Building Polar Crane set the 180t reactor vessel by itself but is currently also de-rated to 200t where is not capable at a 2/1 safety margin to pick it again. |

I once worked at Good Year in Jackson Michigan, building a new tire incinerator to fire a boiler which was to produce power. Left that job before it was complete. I later heard a roomer that it never went into production. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

| They burned shredded tires at Sioux Plant UE(Ameren) a few years, when entered the boiler for maintenance there was all manner of sharp sticker metal tire belting pieces fused to the Cyclone walls and boiler tubing, loads of workers with cuts and small metal fragments imbedded as if from cables that pretty well ended incinerating tires for fuel. |

| Big shops at Allis Chalmers that made those big motors had huge cranes that I used to dodge by going to the can when they had that big stuff overhead. Lol, like it would have mattered as it would have pulled the whole building down. Thought 150 ton but seem to remember they had to bridge two to get that rating. Most of it shipped by rail in pieces probably because coal was brought in same way. Next time I go through dads stuff I will look to see if he has any pictures with cranes in background. |
