steam is lost in the plant through variuos way. But generally it is through heat transfer to the product to be heated by the steam. Also heat transfer through the conducting passage.
There is no such thing as a heat power cycle in a steam engine.The power stroke, or strokes, result from pressurised steam being let into the cylinder and moving the piston.
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
The reactor in a nuclear power plant generates heat to flash water to steam, which spins turbines that generate electricity. This is not really any different, in terms of steam cycle1, than a fossil plant. Its just that the source of heat is nuclear fission of (usually) uranium-235 instead of the burning of coal, oil, or natural gas. ----------------------------------------------------------------------------------------------- 1Well, its a little bit different because the nuclear steam supply cycle runs best on a slightly lower pressure and temperature than a fossil fuel plant steam cycle does. Other than that, the steam and generating parts of a nuclear plant are very comparable to a fossil plant.
A shell and tube heat exchanger will have two fluids flowing through continuously. The fluid in the tube will typically be the important fluid, the fluid you are trying to heat or cool. The fluid in the shell will then be the fluid that is heating or cooling the the fluid in the tube.Take a steam heat exchanger for example. Steam condenses in shell, while the the fluid in the tube picks up the heat from the steam. And in a perfectly efficient steam heat exchanger, all the heat lost from the steam would be recovered by the liquid in the tube.But nothing is perfect. A little bit of the steam's heat makes the outer shell hot, and that in turn heats the room. Heat is lost from the steam into places other than the fluid in the tube. So efficiency measures how much of the heat lost by the shell fluid makes it into the tube fluid.Efficiency (for heating) = Amount of Heat that went toward heating the fluid divided by the amount of heat that was lost by the heating fluid.So an efficiency of 1 is perfect. For every 1 unit of heat absorbed by the tube fluid, we spent 1 unit of heat from the fluid in the shell fluid.And if the efficiency is 0.9, or 90%, then for every 10 units of heat that the shell fluid lost, the tube fluid gained 9.Sometimes efficiencies are as bad as 40%. In this case for every 10 units of heat lost by the heating fluid, 4 units are gained by the fluid.A slightly different definition of efficiency applies to cooling:Efficiency = Amount of heat lost by the tube fluid divided by the amount of heat gained by the shell fluid.Same story, if the shell fluid gains 5 units of heat, and tube fluid loses 4, then the efficiency is 0.8 or 80%.
If you heat steam under pressure you get "superheated steam" under higher than original pressure
Heat from the nuclear reaction changes water to steam.
There is actually several answers, depending on what you are looking for in your answer. Heat energy, the energy that is imparted to the steam from an external heat source. motive energy, the energy in the steam that moves it through the piping. internal energy, the energy that causes the steam to expand. external energy, the energy that the steam holds that can be used to heat or drive machinery. and entropy, the unuseable energy that is lost in any energy system, (loss to the universe).
The efficiency of a steam power plant is typically around 30-40%. This means that only 30-40% of the thermal energy from the fuel is converted into electrical energy, with the rest being lost as waste heat. Factors such as the type of plant, operating conditions, and technology used can affect the efficiency.
In a steam heating system, the pipes transport steam or water vapor to the radiators to heat the building. Insulating the pipes reduces the amount of heat lost to the surrounding environment. Any heat lost in the pipes cannot be used to heat the radiators, and causes the system to be less energy efficient.
Heat from the nuclear reaction changes water to steam.
To convert the heat of combustion to steam which can be used in an engine.
Chemical energy is released when the coal burns with oxygen in the air. This energy is used to heat water, which is converted into steam. Not all of the energy is used to heat the water. Some of it is wasted by being transferred as heat to the surroundings. The energy of the steam is used to turn the turbines, but some of the steam energy is wasted.
The purpose of the heat in a nuclear power plant is to create steam from water. This steam is then used to drive a turbine connected to a generator, which produces electricity. The heat is generated by nuclear reactions occurring in the reactor core.
No It has heat recovery steam generator
Electricity and steam. In some locations the steam is used to heat homes and businesses.
In a nuclear plant, the heat generated by fission is used to heat water to produce steam; the steam then drives a turbine which turns a generator.
