CONVENTIONAL OIL TYPES - The following oil types are suited for use on Solar turbomachinery provided that they are in compliance with all the requirements of this specification. • Synthesized Hydrocarbon Oils (SHC) • Petroleum Oils

1.3 SPECIALTY OIL TYPES - The following oil types are also allowed provided that (1) the oil type is specified in the engineering drawing, (2) compatibility with hoses, elastomers and paints have been considered, and (3) oil cooler is sized correctly relative to heat capacity of oil. Changeover to these oils in the field is not recommended unless Solar is notified and the package is checked for oil compatibility. • Synthetic Ester Oils • Phosphate Ester Oils (Fire Resistant Lubricants)

1.4 USAGE - Where a Solar drawing references this specification without specifying the oil type, only synthesized hydrocarbons and petroleum oils (i.e. Conventional Oils) can be used as defined herein.

STEAM TURBINE

The Steam turbine in CCP power plants

The steam turbine of a solar thermal power plant is robust and simple equipment, and as industrial machine is a mature, well-known and very experienced machine. It is known almost everything about her, their mechanical behavior and thermodynamic operation principles. Over 70% of electricity generated worldwide is daily produced with steam turbines.

The turbine is the equipment responsible for transforming potential energy in the form of steam pressure in rotational kinetic energy. The operation is very simple: introducing steam at a particular temperature and pressure and the steam expansion inside the casing to make the blades attached to a rotor shaft rotate, at turbine’s outlet, the steam comes out at a lower pressure and temperature. Most of the energy lost by steam between the inlet and outlet is used to move the rotor, and a small fraction is lost in the form of friction of the steam with the shaft’s fixed parts, the friction between shaft and the bearings, housing heat losses in the form of radiation, conduction or convection, and internal or external steam leaks.

The turbine also requires very simple auxiliary equipment such as a lubrication system, oil cooling lubrication, a regulation and control system, steam inlet and outlet tubes, a soundproofing enclosure adequately ventilated and a foundation and supports to lean on
