| Abstract |
Power plant projects in general and renewable power plant projects in particular require numerous decisions and choices. Some of the most obvious questions for geothermal power plants are geographical region, site, plant type, financing and power purchase agreement. Some of the next tier decisions had to do with types of evaporators, condenser, turbines, generator, controls and control logics. There are several lower tier decisions that are not going to be discussed in this writing. The objective of this article is to highlight one important feature of turbine, variable inlet guide vanes, and present its utilization in an inflow radial turbine or turbo expander. |
