As the world looks towArds solAr energy As A focus for the future of Power generAtion, PentAir vAlves & controls is AlreAdy meeting the chAllenge with An extensive rAnge of key Products sPecificAlly suited to the thermAl trAnsfer And high temPerAture APPlicAtions required for this rAPidly exPAnding sector of the industry.

solar power is in the midst of a boom. over 5,800 Mw of solar power projects are in the planning stages worldwide, with the majority expected to come online by 2014.

the potential is huge in many regions of the world, given that one square kilometer of land is enough to generate as much as 100-300 gigawatt hours (Gwh) of solar electricity per year using solar thermal energy. that’s equivalent to the annual production of a 50 Mw conventional coal- or gas-fired mid load power plant.

producing energy from the sun’s rays is a straightforward process, with direct solar radiation being concentrated and collected by a range of technologies such as:- concentrating solar power (csp)

- integrated solar combined cycle system (iscc)

- compact linear Fresnel reflectors (clFr)

- central receiver systems (crs) or solar tower

- Dish stirling technology

whichever of these is used to generate power, you can rely on pentair valves & controls to provide the products and services which will enhance the process and maximize results. our valves and actuators are proven in critical high temperature applications, and specifically in Heat transfer Fluid (HtF), molten salt, steam, feed and circulation water processes.

concentrAted solAr Powerwith thermal energy storagetrough technology bases its operation on solar tracking and the concentration of solar rays on receiving tubes with high thermal efficiency, located on the focal line of the cylinder. in these tubes, a heat transmitting fluid (HtF, heat transfer fluid) such as synthetic oil is heated to approximately 400°c by the concentrated solar rays. this oil is pumped through a series of heat exchangers to produce steam. the heat present with such steam is converted into electric energy on a conventional steam turbine. energy storage is necessary for successful implementation of csp technology.

centrAl receiver systemsolar tower systems operate through a field of heliostats that reflect solar radiation onto a central receiving tower. the heliostats are two-axle tracking mirrors that follow the sun over the course of the day. At the receiver, the solar radiation can be concentrated up to 600 times the normal solar radiation. the radiation energy is transferred to a working fluid that flows through the tower.

After absorbing the heat energy at the tower, the working fluid can generate steam to run a turbine and produce electricity.

our specialist teams and experience make pentair valves & controls your ideal partner in geothermal power generation. whether your plant utilizes a flash steam, binary or combined cycle system, we can provide you with solutions to optimize and control your operation, reducing your costs and increasing your uptime.

Geothermal energy currently produces enough electricity to meet the needs of more than 60 million people across 24 countries. By 2015, around 36 Gw of

geothermal power is expected to be in use worldwide.

one of the key drivers of investment in geothermal power generation is its environmental benefits. Geothermal facilities emit only steam, because no combustion takes place. emissions of nitrous oxide, hydrogen sulfide, sulfur dioxide, particulate matter and carbon dioxide are extremely low when compared to fossil fuel emissions. in addition, these facilities require only about 11% of the land area used by a coal power plant (per gigawatt hour generated).

Geothermal power is not limited by resources or atmospheric conditions and can be a reliable source of power for decades. pentair’s range of valves and actuators is designed and engineered with this reliability and longevity in mind. we are experienced in managing the most aggressive fluids and have developed solutions

for corrosive, saline and abrasive environments – while providing zero leakage. these solutions include nAce specification.

our staff of engineers will not only help you choose the optimal solution for your application but also work with you through the entire process. Given the nature of geothermal power generation, plants can differ significantly in terms of operating conditions, design and requirements. our unparalleled technical support assures smooth installation and commissioning, and our wide range of solutions enables you to choose the best option to build or retrofit your plant.

flAsh steAm Power PlAntFlash steam power plants are the most common type of geothermal power station. Hot water is pumped at high pressure to the surface. this requires valves and actuators capable of handling conditions. the heated water flashes to steam on reaching the cooler surface, powering a turbine. once the steam has cooled, it is returned to the geothermal reservoir.

binAry cycle Power PlAntBinary cycle power plants represent the newest technology in geothermal applications. A heat exchanger is used to transfer energy from the hot water to a heat transfer fluid with a low boiling point, improving efficiency. the water from the earth never comes into contact with the turbines, which minimizes emissions of trace gases into the atmosphere.
