A power plant of the conventional steam turbine/generator type, whether using fossil fuel or a nuclear reactor, operates by pumping feedwater at high pressure into the steam raising units, the steam is admitted to the turbine which has various stages. At the high pressure end the rotor blades are short but they get progressively longer as you go down the machine, because the steam is expanding to a lower pressure so has a greater volume. At the back end where the steam comes out of the turbine, you will get maximum power and hence maximum efficiency of the plant by having a vacuum, so that steam below 100 degC is still doing useful work. Hence the condenser cooled by ambient temperature water from an outside source, where the below atmospheric pressure steam is condensed to water and returned to the feed pump inlets. So you may see the condenser as wasting heat, but in fact it considerably increases the overall efficiency. This steam/water cycle is called the Rankine Cycle and you will find an article on this in Wikipedia.
What else can I help you with?
Why steem do not send to the boiler insuded of condenser?
In a typical steam system, steam is directed to the condenser instead of the boiler to remove heat and condense it back into water for reuse. Sending steam to the boiler would be inefficient, as it would require additional energy to convert the water back into steam again. The condenser allows for heat recovery and improves the overall efficiency of the system by recycling the condensate. This process also helps maintain optimal operating conditions and reduces water consumption.
How boilers are classified?
A high pressure steam boiler is boiler in which steam is generated at pressure exceeding 15 psig and operates hot water boiler above 160 psig or 250o F. Application this type usually is used for utility plants, big industrial plants and process application. A high pressure steam boiler can be named as Power Boiler, in which design and construction rule following to rules of ASME Boiler and Pressure Vessel Code Section I - Power Boiler.
Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
Why steam is to be condensed in thermal power plant Y should not you use a compressor to suck compress and send back the steam at high pressure?
It's a matter of the steam cycle, the condenser in a condensing power plant creates a vacuum, or low pressure zone for the steam to flow into. A compressor would need to compress this steam 650 times plus generate enough force to force it back into the boiler, this would require a lot of energy to do. It is much simpler and much more cost effective (energy wise), to condense the steam and exhaust the excess heat to the cooling tower. The condensed water can then be pumped back to the boiler in stages to repeat the cycle. In these stages the water is de-aerated, treated and heated back to the boiler's temperature to prevent thermal shock in the boiler. In short condensing the steam is easier, safer and cheaper than trying to mechanically compress it. **By the way, there are vacuum pumps called "hoggers" or steam powered ejectors, and injectors which could do just what you suggest, but use exorbitant amounts of energy to do so. These are typically used in conjunction with condensers to eject non-condensible gasses from condensers.
Who invented the steam boiler furnace?
Granville T. Woods invented the Steam Boiler Furnace
What does a condenser in a coal-burning power plant do?
A condenser in a coal-burning power plant is used to convert the steam that has passed through the turbines back into water. This water can then be reused in the boiler to create steam, making the power plant more efficient by reducing water consumption.
Will the steam power plant works without condenser?
no
Does combined cycle power plant has a boiler?
No It has heat recovery steam generator
What is the purpose of a nuclear condenser?
A nuclear condenser is used to convert steam back into water in a nuclear power plant. This helps to increase the efficiency of the power plant by allowing the steam to be reused in the reactor's cooling process. Additionally, the condenser helps to reduce the environmental impact of the power plant by minimizing water consumption and preventing water pollution.
How is boiler works on power plant?
it make high pressure steam to be sent to the turbines.
What are the key components and processes depicted in a Rankine cycle diagram?
A Rankine cycle diagram typically shows four main components: a boiler, a turbine, a condenser, and a pump. The process involves the heating of water in the boiler to produce steam, which then expands through the turbine to generate power. The steam is then condensed back into water in the condenser before being pumped back to the boiler to repeat the cycle.
How does steam condenser work?
the work of the condensor is to condense the hot steam and change its state so that it can be used again in boiler
What is Auxiliary Boiler?
An auxiliary boiler is a secondary boiler used to support the main boiler in a steam power plant or marine vessel. It is often used when the main boiler is unable to meet the steam demands, providing additional steam capacity. Auxiliary boilers can also be used for heating purposes during maintenance or downtime of the main boiler.
What is the use of vacuum pump in thermal power plant?
A vacuum pump is used to expel air and non-condensible gases from the condenser in order to allow it to continue accepting steam (the collapse of which produces the vacuum in a condenser). If the vacuum pump fails, it will take from seconds to a few minutes before enough non-condensible gases build up in the condenser to stop the flow of steam. The non-condensible gases come from the boiler feedwater supply, despite the fact that boiler water is treated to prevent this. The minute amount of air in the water is carried with the steam into the turbine then the condenser where it will concentrate unless removed by the vacuum pump.
Why steem do not send to the boiler insuded of condenser?
In a typical steam system, steam is directed to the condenser instead of the boiler to remove heat and condense it back into water for reuse. Sending steam to the boiler would be inefficient, as it would require additional energy to convert the water back into steam again. The condenser allows for heat recovery and improves the overall efficiency of the system by recycling the condensate. This process also helps maintain optimal operating conditions and reduces water consumption.
Why you use cooling towers in thermal power station?
This is to cool the steam turbine condenser, where the steam outlet from the turbine's last stage is condensed before returning to the boiler feed pump inlets. The cooling towers circulate water that passes through tubes inside the condenser, separate from the steam/water in the boilers.
What are the advantages and disadvantages of condenser?
A condenser is a device which condenses the steam at the exhaust of turbine. Condensers are classified in to two types.Such as (1) Jet condenser (2) Surface condenser It serves important functions. Such as 1. The condenser enables the recovery and recirculation of pure feed water into the plant. Thus, (i)The cost of water softening plant is reduced and (ii) It also saves the cost of fresh water to be supplied to the boiler.
