Steam Turbines

You see on those drawings, in the bottom right corner, yes, that's it. Look. The phone number of the firm that is producing the equipment you're installing? Try ringing it. Try talking to the individual at the other end. Because I'm not going to do it for you.

You could also open the manual that came with it, and read it. Because I'm not going to do that for you either.

How lazy!

There is a guy on here named Bin 95 who does tutorials on subjects like this. In most cases, there is probably a fee, but he still might have some good suggestions for you.

You may well be right about the gland condenser. Look for condensate piping and see where it goes.

I'm not a steam turbine guy, but the diaphragms or baffles might be to direct steam flow from one blade set back to the outside of the next blade set (i.e., multi-stage operation).

Factory personnel should be willing to explain their design features so that you and others can understand the operation correctly and maintain the turbine properly.

thanks TORNADO your answers have always been decent as much as you.

Quite welcome. Best wishes for continuing lifelong education and successful operation of your equipment.

Gland condensers are used to condensate the steam from the turbine labyrinth glands removed by the eductors and return it to the boiler water system. The bearings are always located outboard of the labyrinths and there should never be any risk of oil contamination. I've never seen a turbine where the bearings are inboard of the glands since there would be more damage from water getting into your lubrication system. That is why centrifuges are used to separate the water and other contaminants out of the oil. The temperatures in the HP turbine would also cause the oil to vaporize in many cases. The gland condenser also removes the steam that has to be provided to a condensing LP turbine gland to prevent air infiltration due to the vacuum.

The diaphragms separate the stages of the turbine. In a reaction turbine they act as nozzles and reverse the flow as well as change the velocity and volume. Impulse turbines use them to reverse the direction to impinge on the next rotating stage. Diaphragms are basically the stationary stage that reverses the direction of flow. Most turbines incorporate both in their design. Reactionary stages are generally used in the primary stages and then impulse stages are used. Often the LP turbine and Reverse stages as in Marine Turbines are almost always entirely impulse.

Suggest you Google Reaction Turbine stages and Impulse Turbine stages to further your understanding. good luck.
