What is DMCW pump?
Pump/ De-Mineralised Cooling Water. (DMCW) Pump. 5. Auxiliary Cooling Water (ACW) Pumps.
What is ACW pump?
Q. How are auxiliary cooling water pumps (acw pumps) used in combined-cycle power plant service, and what pump types can be used? The fluid pumped from auxiliary cooling water pumps is clean, high-quality water, unlike the main cooling system, which takes water directly from the cooling tower or other sources.
What is ACW in thermal power plant?
Condition Monitoring of Vertical Auxiliary Cooling Water (ACW) Pump at Thermal Power Plant.
What is CEP power plant?
Condensate extraction pumps (CEP) extract the condensate water from the condenser and pump it through the condensate polishing system and the LP heaters to the de-aerator feed water tank. The CEP are vertical canned type to ensure Net Positive Suction Head Available (NPSHA).
What is DMCW medical?
Diploma in Maternity and Child Welfare (DMCW) – Maternity and Child Welfare is a branch of medicine that deals with offering care to the new born child and the new mother. This branch of medicine also offers medical care to the mother, who is going to give birth to a child.
What is power plant cooling tower?
A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature.
Which pump is used in boiler?
centrifugal pumps
Today, all boiler feed pumps are centrifugal pumps. The design of boiler feed pumps regarding power input, material, type of pump and drive is largely governed by the developments which have taken place in power station technology.
What is the purpose of CW?
The prime object of a circulating water (CW) system is to cool the LP turbine’s exhaust steam to convert it to condensate. Typically, the cooling water causes the steam to condense at a temperature of ∼45.4°C (113.7°F) and that creates an absolute pressure in the condenser of ∼0.1 kg cm2.
Why CEP is vertical pump?
The CEP are vertical canned type to ensure Net Positive Suction Head Available (NPSHA). In small plants, they can also be horizontal end suction type. In medium to large size coal- and oil-fired power plants, the CEP are vertical canned type to ensure enough Net Positive Suction Head Available (NPSHA).
