    There are 3 types of cooling systems in termal power plants. Whether it is coal or Nuclear. They are Direct or "once-through" cooling, Recirculating or indirect cooling. and dry cooling. In the video you see Direct cooling. This type of power plans are build next to large rivers, lake or see where there are an limited cold water to be used to condense the steam. They take water from river and pass it trough condenser and discharge it back to the river.

    Because while pressure decreasing the specific volume of the steam is increasing. To accommodate expansion, cross section of steam passing area should increase. Also, you should know that for the gases decreasing the flow area does not mean to increase velocity. This is true up to a point, then area should increase to increase the speed of the gases. Look at a rocket nozzle. Area first decrease, when speed of the gas reaches speed of sound, the area begin to expand so that speed of gas increase

    During this process temperature of river water rises slightly. So you may not see any steam coming out from power plants. If there is plenty of coal in a location but not enough water than the second type, recirculating cooling is used. In this case water from a small reservoir is fed to cooling tower where water droplets flow downward in between condenser pipes, during this time steam condenses and some cooling water, %5, evaporates.

  • @mekanizmalar
    @mekanizmalar  11 років тому

    In this type power plants you may see steam is coming out from cooling towers. I do not have much knowledge about dry cooling, but it is using air just like car radiator, so you may not see steam coming out at all.

    Never understood why the Archimed force has never been used to amplify the power during boiling...
    The quantity of heat lost is also crazy...
    You've never heard about refractive materials and perlite to isolate from the outside ?
    If you create a refractive pizza cooker, with the boiler in the middle, in a hole with perlite
    linked to an isolated tank with first Archimed force, then pressure force, finishing on peltier effect, to conserve all energy, results could be really beneficial for everybody
    Also temperature control is optimal, and the rocket stove device type, linked to a big refractive isolated rock can conserve a Hugh temperature for a very long time
    Rocket stoves can run with small pieces of wood no need to cut the trees, only re-use the cleaning parts to generate winter energy heat, boiling water, electricity, whatever you need

    Dear Stevie, The reason it is called waste heat because you can not extract more power from it. According the thermodynamic principles there is no way you can get more power from it. Yes, you can use that heat for heating buildings or you may keep some sea ports ice free. However power production and consumption creates thermal islands called cities which attract some animals and destroys habitat of other animals. Winter time city of Rome attract billions starlings and Romans don't like it.

    Why is it necessary to cool the steam forcefully? Isn't it lowering the efficiency??

    • @Mukation
      @Mukation 7 років тому +1

      1 litre of water becomes 1,7 Cubic meters of steam (or 1700 litres). So to "naturally" cool a powerplant fast, you'd need to have a condensor that is riddiculously large or have an inccreddibly slow process (thus less power), which is impractical and time consuming. So by forcefully cool it you actually save time and space.

    • @mekanizmalar
      @mekanizmalar  7 років тому +1

      Not necessarily. Steam turbines working with high efficiency allowed by thermodynamic principles. You need a closed loop water and steam flowing inside the plant. You need closed flow loop for two reasons. The first is that you can't add water to the system just as you do in steam locomotives, calcium or any impurities will clog the tubes with time. Any water lost, which is minimal, is replaced by softened water. The second reason is the exit pressure from the steam turbines is under atmospheric condition, to increase efficiency. Also, the steam leaving the turbine is in saturated conditions, meaning it is about to turn to water. Removing some heat from this saturated steam will quickly turn it into water. If you do not do that, you have to pump this saturated steam back to the boiler, which requires a lot of power.
      To understand this process, it is best to study Rankine Cycle on Mollier Diagram.

    • @seyhanersoy8989
      @seyhanersoy8989 4 роки тому

      There are two reasons to do it this way. First, the exit of steam from the turbine well under atmospheric pressure for efficiency reason. If you do it the way you described, the turbine would inefficiently. The second reason is that they purify the recirculating water, meaning they remove lime from hard water. If the system was open, and resupply water from outside, some water pipes would be clogged and the life of the power plant would be short.

    "Why is a very small portion of pressurized steam diverted to the bearing section of the turbine, where the low pressure steam leaves the turbine?"
    Has anybody found the answer for it ? or maybe even you know how to answer :)

    • @seyhanersoy8989
      @seyhanersoy8989 2 роки тому +1

      Power plants work with a closed water cycle, this is because the water is used is almost %100 pure. Otherwise, the pipes will be clogged with time. This will create a herculean task to clean the pipes. If so why do we allow this precious steam to escape from the turbine bearings where low-pressure steam leaves the turbine. Since steam leaves the turbine well below atmospheric pressure air will enter into the turbine circulation system. It is a very difficult task to get rid of this air. For this reason, a steam a little bit higher pressure than atmospheric pressure sends the middle of bearing. Then steam follows two paths, one toward the turbine circulation system, and the other leaves the turbine, Since the steam is above atmospheric pressure, this blocks airflow into the turbine.

    • @seyhanersoy8989
      @seyhanersoy8989 Рік тому

      There are many reasons for this. This is the closed-loop cycle. This is because the steam leaving the turbine is well below atmospheric pressure. Also, we don't want pipes in the steam cycle not clog the pipes. For this reason, water in the closed-loop cycle is distilled water. The power plant will be inefficient if the steam leaves the turbine above atmospheric pressure. If we feed the water to houses, we should use the same amount of distilled water, and this makes the operation of the power plants costly.

It's A dangerous job do not get me wrong . I only worked for A few years underground but the time I was underground I always felt safe . The only reason that I felt safe was the people . The best people I have ever met in my life . Hardest working , most intelligent , down to earth people you would ever meet . The mines that have been shut down in this area have devastated the economy . They just shut down A whole hospital In Lee county . The effects are on our jobs . Now there are a few large mines still open for NOW . But all of that coal goes to China , to support the steel industry that left the rust belt behind . I worked my butt off to get the best job of my life and then politicians threw it away for Fracking . I mean come on have you even looked into what kind of chemicals they are pumping into our ground water . These people do not care . They make their millions , billions and move to another country leaving us with out any jobs . Were drinking hydrochloric acid ...THEY....... Then say " Well it's good for the environment " ......are you freaking kidding me .
    Please people reading this spend a few moments of your time and look into fracking

      Let's make something clear. Coal creates CO2 which is biggest contributor to global warming.Are coal producer the evil people destroying our planet? Should we close all the coal production fields to save our world? My answer to these two question is absolutely not. We live in an economic system based on supply and demand. Find an energy source cheaper than the coal, people will buy that energy, rather than coal based energy. So they are doing a service to us. But; by product of this service is also creates big problem for us. Why we are so dependent on cheap coal so heavily to the extent to destroy our planet. The problem is not the coal producer, the problem is the other industries making us so dependent on coal.
      One example is home builders. They are making houses so energy inefficient, so huge, that we spent fortune to heat them in the winter. All the manufacturer, whether it is ink jet printer, battery powered power tool, car or many similar manufacturer makes their product not to fit other manufacturer product creates over use of energy unnecessary and keep prices artificially high. In short our problem is not global warming, our problem is over crowding and the greed. Solve over crowding problem and make laws to protect poor from greed of the powerful will solve many of our problems.
