The United States may have to build many new power plants to meet growing demand for electric power. For example, the Energy Information Administration (EIA) estimates that the nation will have to construct 226,000 megawatts of new electric power generating capacity by 2030. 1 This is the equivalent of about 450 large power plants.

For cooling, industrial heat pumps are used to recover waste heat for heating the plant and its water. More cooling power is drawn from the ground. The hybrid system, which replaces natural gas, utilizes geothermal heating and cooling in addition to the heat pump system in its heating and cooling .

 · CHILLERS Provide chiller packages with centrifugal compressors, or screw compressors, and water cooled condensers. Design the chiller plant with at least two chillers if the total capacity is more than 400 tons. Size one chiller for 1/3 of the load and the other chiller for 2/3 of the load. Include equipment KW/Ton and APLV values in a selection criteria.

A centrifugal pump is one of the simplest pieces of equipment in any process plant. Its purpose is to convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. The energy changes occur by virtue of two main parts of the pump, the impeller

Therefore, cooling the process water as much as possible is desirable to the power plant to maintain high energy efficiency, which raises the temperature of cooling water. In response, most state regulations set a hard limit on cooling water maximum temperature, usually around the 3040°C mentioned above, regardless of season or ambient cooling water inlet temperature.

 · Drycooled systems use no water and can decrease total power plant water consumption by more than 90 percent. The tradeoffs to these water savings are higher costs and lower efficiencies. In power plants, lower efficiencies mean more fuel is needed per unit of electricity, which can in turn lead to higher air pollution and environmental impacts from mining, processing, and transporting the fuel.
