Primary Cooling Water Circuit In The Generators :
The treated water used for cooling of the stator winding, phase connectors and bushings is designated as primary water in order to distinguish it from the secondary coolant (raw water, condensator etc.). The primary water is circulated in a closed circuit and dissipates the absorbed heat to the secondary cooling in the primary water cooler. The pump is supplied with in primary water cooler. The pump is supplied with in the primary water tank and delivers the water to the generator via the following flow paths:
Flow path I :
Flow path I cools the stator winding. This flow path passes through water manifold on the exciter end of the generator and from there to the stator bars via insulated bar is connected to the manifold by a separate hose. Inside the bars the cooling water flows through hollow strands. At the turbine end, the water is passed through the similar hoses to another water manifold and then return to the primary water tank. Since a single pass water flow through the stator is used, only a minimum temperature rise is obtained for both the coolant and the bars. Relatively movements due to the different thermal expansions between the top and the bottom bars are thus minimized.
Flow Path II :
Flow path II cools the phase connectors and the bushings. The bushing and the phase connectors consist of the thick walled copper tubes through which the cooling water is circulated. The six bushings and phase connectors arranged
It also has a distillation column which is used for a specific separation of two chemicals or solvents. It separates two solvents at a high degree of

The Economic Simplified Boiling Water Reactor (ESBWR) is the latest evolution of GE Hitachi Nuclear Energy 's proven advanced Boiling Water Reactor (BWR) technology. This simplified design provides better safety and plant security, a broad seismic design envelope, greater economy, and operational flexibility. The ESBWR is the safest current nuclear plant design, exceeding U.S. safety standards 100-fold and produces nearly zero greenhouse gas emissions.
Answer: The distillation apparatus consists of a round bottom flask connected through an adapter to a condenser, which is connected through another adapter to a second round bottom flask (Yee, n.d., Distillation). There is a thermometer connected through the thermometer adapter at the top (Yee, n.d., Distillation). There is also a vacuum adapter and a heating mantle. The heating mantle is a coil which heats through electrical resistance (Yee, n.d., Distillation). You use cold water and make sure that it goes in through the bottom and out through the top (Yee, n.d., Distillation).
First, the simple distillation apparatus was set up. An oil bath was placed on a hot plate. A 100mL round-bottomed flask was submerged in the oil and held using a clamp and ring stand. The round-bottomed flask was then connected to the distillation head ensuring that the joint was greased. The thermometer was placed inside the distillation head so that the top of the bulb was level with the arm of the distillation head. The distillation head was attached then to the condenser held up by a clamp and ring
The stability of the refrigerant circuit has to have the focus on end customer relevance. So if there is no hunting seen in the refrigerant circuit, no further actions are needed regarding to stability.
The source of coal for the power station and oil for starting and operating will be supplied from Indonesia by ship and transferred from the unloading seaport to the site
The Great River Energy’s baseload power plants can be described as the backbone of our electric generation system. These plants run all day, every day in order to meet the energy needs of each city. These power plants run on coal. The Great River systems own and operate several natural gas peaking plants in the state of Minnesota. These plants generally run on the hottest and coldest days of the year, when demand for electricity is especially high. The plants use natural gas or fuel oil to generate electricity. Because plants are more expensive to operate, they put them into service only when necessary to increase capacity. Elk River uses a cleaner way to harness electricity as its main source for energy. Biomass, which is a renewable energy
This method of cooling techniques is theoretically able to reduce temperatures from 50 to 27 degrees Celsius. The bidding committee also proposes to use such cooling technologies in fan-zones, training pitches and walkways between metro stations and stadiums.
The pipe experiences heat transfer by means of internal convection from the CO2, conduction through the pipes material, and conduction from the permafrost. The overall heat
Heating might happen inside the chopper so that heat sink can be attached for proper dissipation of heat. Also to get more heat concentrated equally on the module, a metal plate is used which spreads the heat. To provide external support all the elements are fitted inside a box. Heating, an important phenomenon is provided with the help of byproducts from both the industries and domestic areas and in absence of byproduct, candle flames or woods can be used as the source. It is provided to the Peltier modules which are connected to the cooling source. Cooling can be provided by chilled water or ice storing into a metal tray or heat sink can be fixed with the Peltier modules and use of a fan to dissipate the heat and provide cooling. This arrangement starts producing voltage in some time and that too without making any noise. Also, the rigid construction can wield a much and the Peltier modules itself can easily work for a long life span without any failures.
Phase connectors and the Bushings are cooled by Flow Path II . The cooling water is circulated through the thick walled copper tubes of the
In a counter flow heat exchanger the two fluids flow parallel to each other but in opposite directions. The counter-flow heat exchanger provides the most thermally effective arrangement for recovery of heat or cold from process streams. A counter flow arrangement is thermodynamically superior to any other flow arrangement. It is the most efficient flow arrangement, producing the highest temperature change in each fluid compared to any other two-fluid arrangement for a given overall thermal conductance (UA), fluid flow rates and fluid inlet temperatures. Cryogenic refrigeration and liquefaction equipment use this geometry almost exclusively. But this type of heat exchangers demands proper design because of the complex geometry
Abstract— for four hydro and three thermal plants of short term hydro thermal scheduling, teaching learning based optimization techniques have been applied. This technique is a newly developed evolutionary procedure built on two simple concepts of education specifically, teaching stage and learning stage. In primary stage, learners improve their knowledge or capability with the help of the teacher and in secondary stage learners increase their knowledge by exchange among themselves. Results for four hydro and three thermal model test systems are conducted to generate optimal solutions of HTS problem. The reservoirs are cascaded and the control variables are non-linear relationship between water discharge rate, net head and power generation is considered. The delay of water transport between the cascaded reservoirs are also taken in to consideration. The results obtained by the different techniques were compared with this proposed technique, it is seen that the proposed technique got optimal results
