reason for low vacuum in condenser system in india
Understanding Process Vacuum Condensers - Graham Understanding Process Vacuum Condensers Process vacuum condensers are an integral part of a vacuum system So often, a process vacuum condenser is considered stand-alone equipment, with little consideration given to how best to integrate it into a vacuum system. Common practice has the vacuum condenser specified as just another heat exchanger.

why a vaccum is created in condenser - ALLInterview why a vaccum is created in condenser .. Answer / c.reddi sankara Sudden expansion of steam in the condenser space which is higher enough to drop the pressure below then atmospheric pressure is the cause to create negative pressure or vacuum.(And air pumps are also used to create vacuum).
Condenser in Thermal Power Plants - power4you.co.in But the main reason for the creation of vacuum in the condenser is that when high volume steam converts into the low volume water then the vacuum is generated in the condenser. For maintaining vacuum in the condenser we use 2 types of equipment; 1) Air Ejector. 2) Vacuum Pump. In the air ejectors, we also use steam for its operation.
Large Steam System Condensers - Heat Exchanger - Engineers Edge Large Steam System Condensers: Heat Exchanger Knowledge | Heat Exchanger Companies Suppliers. The steam condenser, shown in Figure 9 below, is a major component of the steam cycle in power generation facilities. It is a closed space into which the steam exits the turbine and is forced to give up its latent heat of vaporization.
What are the factors limiting the condenser vacuum at 0.9? Yes We can go below 0.9 Vacuum but you have to use the condensate again back into the Boiler to Generate Steam. If we go below the 0.9 Vaccum then the energy required to go beyond that vaccum and raising the temperature of those condensate before putting it back into the Boiler will not be optimum.

Why are steam condensers operated at the vacuum? - Quora Answer to this question is very simple, the steam is at high pressure in boiler's drum around 60 ksc to 200 ksc. One has to put this steam in the turbine to extract work from enthalpy of steam.
Thermal power station - Wikipedia The energy of a thermal power station not utilized in power production must leave the plant in the form of heat to the environment. This waste heat can go through a condenser and be disposed of with cooling water or in cooling towers. If the waste heat is instead utilized for district heating, it is called cogeneration.
What causes condenser high vacuum in the steam plant and what ... Vacuum pump maintaining vacuum in steam condenser and as vacuum increases steam pressure at exit of turbine is low so results into fasten the condensation process. 6th Jun, 2016 Siyamthanda Mchophele
Steam turbine condenser vacuum problem - CR4 Discussion Thread Condenser vacuum approx at -925 mbar. Condenser inlet temperature is 29-30 deg C but currently it observed about 31 deg C. Cooling medium is a sea water with 2 CW pumps in service. Problem is observed when condenser vacuum suddenly decreased to -896 mbar from -924 mbar at steady load.
Surface condenser - Wikipedia For water-cooled surface condensers, the shell's internal vacuum is most commonly supplied by and maintained by an external steam jet ejector system. Such an ejector system uses steam as the motive fluid to remove any non-condensible gases that may be present in the surface condenser.
How is a vacuum created in a Main Condenser when it comes to ... How is a vacuum created in a Main Condenser when it comes to power plant operation. View All: Without the use of air ejectors or Vacuum pumps. 10 years ago - 6 months left to answer. - 2 responses - Report Abuse: Respond to question
Condenser - an overview | ScienceDirect Topics A condenser creates the lowest possible turbine back pressure by evacuating air from a condenser shell. A liquid ring vacuum pump and/or steam-jet air ejector is used to maintain vacuum in a condenser. Heat liberated from turbine exhaust steam is removed by either water or air, or a combination of these.
Concepts in Condenser System (Vacuum Equipment) Condenser system and vacuum equipment are common to evaporators and vacuum pans. Nearly all these vessels use direct contact condensers, where the cooling water comes into direct contact with the vapour to be condensed.
SubZero with "Vacuum Condenser" Flashing | FAQ | Sub-Zero ... The Vacuum Condenser message appears when the unit is not running efficiently or temperatures are too high. This can be due to a dirty condenser, a door sealing issue, or a problem with the unit. If temperatures are high, call for service. Ideal temperatures are shown below.

Heat Engines vol 2 condenser to maintain vacuum is limited and the vacuum produced in such a condenser will, therefore, be low. The exhaust steam enters either at the top or the side of the condensing vessel and the cooling water enters immediately below. The cooling water is usually lifted from the source of supply (water tank or cooling pond) to the injection head
