| 説明 | PLEASE, NO invitations or self promotions, THEY WILL BE DELETED. My photos are FREE to use, just give me credit and it would be nice if you let me know, thanks.The Surge Towers are connected to the penstocks located next to the Mill Lake power house and is a very important part of the St. Margaret’s Bay Hydro-electricity system.The surge tower has three important functions:1. Supply additional water on Turbine startup.2. Prevents collapse of penstocks by making available additional water to prevent a drop in the internal pressure caused when turbine is started & suddenly takes water faster than can flow from head pond.3. Prevents penstocks from exploding on turbine shut down, energy from water gained by momentum is released into the surge tower.The two surge towers serving the Mill Lake power plant.The left surge tower is connected to the polypropylene penstock from Coon Lake, although you can’t see the penstock itself it’s position can be seen by the mound of soil where it has been buried.The right surge tower is connected to the fibreglass penstock from Sandy Lake. |
