Ocean Thermal Energy Conversion (OTEC) Plants convert thermal energy from Ocean water to electrical power. OTEC cogeneration plants deliver electrical energy and fresh water. The unit size of turbine generators is in the range of 10MW to 50MW. The plant ratings are of 50MW and 100 MW. Ocean Thermal Energy Conversion technologies are costly and

Parabolic trough This type of collector is generally, used in solar power plants. A trough shaped parabolic. reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station. Parabolic dish It

Flat plate and evacuated tube types of solar collectors are typically used to collect heat for space heating or domestic hot water. A flat plate is the most common type of solar thermal collector, and is usually used as a solar hot water panel to generate solar hot water. A weatherproofed, insulated box containing a

Working of Open Cycle Gas Turbine The most basic gas turbine unit is one operating on the open cycle in which a rotary compressor and a turbine are mounted on a common shaft as image. Air is draw from the atmosphere into the compressor and compressed to pressure of 300 to 400kN/m². The compressed air

The gas turbine power plant has relatively low cost and can be quickly put into commission. Gas turbine installations require only a fraction of water used by their steam turbine counter parts. The size of gas turbine plants used varies from 10MW to 50MW and the thermal efficiency of about 22% to 25%. It is

Testing object oriented software presents some new challenges. Many conventional techniques are still appropriate. For example, functional testing of object oriented software will be no different from functional testing of conventional software. Test cases will be developed based on the required functionality as described in the requirement documentation. However, structural testing of object oriented software

Nuclear energy produced from nuclear fuels is directly involved in power generation. Mostly, nuclear reactor is with steam power plants. Nuclear Steam Combined Power Plant In this combined cycle, heated helium gas is used to run the helium turbine. First, helium gas is compressed in the compressor to raise its pressure and temperature. Then it

A reactor of this shape is a called a tokamak. The most well known of the nuclear fusion test reactors is the TFTR at Princeton. It is a magnetic confinement reactor using the toroidal geometry of the tokamak, a device first developed in the USSR. It uses a combination of two magnetic fields to confine

This is a very high pressure supercritical water cooled reactor which operates above the thermodynamic critical point of water to give a thermal efficiency about one third higher than today’s light water reactors. The supercritical water (25 MPa and 510-550°C) directly drives the turbine without any secondary steam system. Passive safety features are similar to

Like other helium gas cooled reactor which have operated or are under development, these will be high temperature units of 850°C, suitable for power generation, thermochemical hydrogen production or other process heat. For electricity, the gas will directly drive a gas turbine. (Brayton cycle) and steam turbine cycle. Fuels would include depleted Uranium and any
