Two broad types of condensers are: (i) Direct contact type condensers; where the condensate and cooling water directly mix and come out as a single stream. (ii) surface condensers; which are shell and tube type heat exchangers where the two fluids do not come in direct contact and heat released by the condensation of steam is transferred through the walls of the tubes in to the cooling water continuously circulating inside them

What is kenotometer?
A kenotometer is an instrument used in steam turbine condensers to measure the vacuum in the steam space of the condenser. The vacuum achieved by the condenser has significant influence on the efficiency of the steam turbine.
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.
Which is better wet steam or dry steam?
If by dry steam you mean superheated steam then dry steam because it has a higher calorific value
How many kinds of steam?
There are three kinds of steam 1) saturated steam, 2)super saturated steam 3) wet steam.
What is meant by moisture in steam?
whenever there is presence of moisture(water content) in steam due to which one cannot refer that steam as dry steam...then this type of steam are termed as wet steam!!

Why you selecting surface condenser?
Surface condensers are used exclusively to condense steam in thermal power plants. The coolant used for condensing this steam is generally water.
The fans that you see on a roof-top chiller are used to cool the?
Condensers
What has the author R J Law written?
R. J. Law has written: 'James Watt and the separate condenser' -- subject(s): Condensers (Steam)
What are the industry primary products?
They are heat exchangers and steam condensers; fabricated steel plate; steel power boilers, parts, and attachments; metal tanks and vessels (custom fabricated at the factory).
How does energy changes from one form to another in a coalburning power plant?
A power plant works like a heat engine. It receives thermal energy as heat and transforms part of it to mechanical energy discarding the rest as heat to the surroundings. In a coal burning power plant, the coal's chemical energy is liberated as heat and used to generate steam (at the steam generators) at high temperature and pressure. This high energy steam (large enthalpy content) is fed to steam turbines that are coupled to large electricity generators responsible of the plant's electric power output. The exhausted steam (at lower temperature and pressure) is sent to condensers which cool down the steam flow to get a flow of cool liquid water (The condensers require cold water to condense the steam)*. The cool condensed water flow is sent to a pump to lift its pressure high enough to be introduced to the heating system equipment (steam generators). The working fluid (water) has run a a full cycle. *The plant requires a "heat sink", a cooling source for the condensers cooling water. That is why power plants are constructed by a river or by the sea. If that is not an option, cooling towers are required.
How steam turbines be classified?
1) Impulse turbine 2) reaction turbine
Why you called a capacitor as a condenser?
Capacitors were first called Condensers by Alessandro Volta in 1782 when he discovered that the device had the ability to store a higher density of electric charge than a normal isolated conductor.The name was changed to capacitor after 1926 to avoid confusion with other types of condensers, like those on steam engines. Exactly who coined this new term has been lost

What system uses compression pumps and condensers to the cool air?
Heat pumps use compression pumps and condensers to cool air.
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.
What are the three types of condensers?
shell and tube
