receives condensate pumped by the condensate pump. 4. Boiler feed pump: It is a pump, which pumps the condensate from the hot well to the, boiler. This is done by increasing the pressure of condensate above the boiler pressure. 5. Air extraction pump: It is a pump which extracts (i.e. removes) air from the condenser. 6. Cooling tower: It is a ...
Customized condensate extraction pumps for gas-fired plants. 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. In medium to large size gas-fired combined-cycle power plants, the CEP are vertical canned type to ensure enough Net Positive Suction Head …
CONSTRUCTIONAL FEATURES OF CONDENSATE EXTRACTION PUMP DESIGN FEATURES OF CEP Vertical, Multi Stage, Multi-Shaft. Can type construction with suction nozzle integral with Canister. Double Suction first stage Impeller for minimum NPSHR. Balancing holes and tilting pad Thrust Bearing for Axial Thrust. Cutless rubber line bearings with axial flutes.
The condensate extraction pump is used to do the initial part that draws the condensate under vacuum from the condenser hot well with some positive pressure at the discharge. This water, after passing through several heaters and deaerators, reaches the suction of the BFP that is used to pump water at a very high pressure.
Condensate Extraction Pumps: C ondensate Extraction Pumps are used to pump the condensate water from Condenser Hot Well to Deaerator. These pumps are designed with a very low Net Positive Suction Head (NPSH) requirement. These are vertical, multistage centrifugal pumps of wet pit type mounted in a canister.

• A pump called the wet air pump to remove the condensed steam (condensate) the air, and . ... In this type of surface condenser the suction pipe of the air extraction pump is placed in the .
Condensate Pressure Power Pump; Recovery of the Energy in Flash Steam. Condensate pipe carries approximately 90% (by volume) of flash steam, and 10% of condensate. ... Solvent extraction plants. Calculation of Flash Steam Generation % Flash Steam Generated = (hf1 – hf2) x hfg2 Where, hf1 = Enthalpy of water at the higher pressure in Kcal ...
GE's condensate extraction pumps are the vertical multi-stage bowl diffuser type, or can type, with a single- or double-suction impeller. The can is arranged in a pit below the installation floor. We offer various configurations, with or without a pump in stand-by. Variable speed drives are available for all types of reactors and specifications, including large flow requirements.
Oct 27, 2020· There are mainly three types of jet condensers.. Low level condenser. High level condenser. Ejector condenser. Low Level Condenser. Here condenser chamber is placed at low elevation and overall height of the unit is low enough so that the condenser may be directly placed beneath the steam turbine, pump or pumps are required to extract the cooling water condensate and air from the …
Mar 09, 2013· Condensate Pumps The function of these pumps is to pumps out the condensate to the deaerator thru' ejectors, gland steam cooler, and L.P. heaters. These pumps have four stages and since the suction is at a negative pressure, special arrangements have been made for providing sealing.
The pump also provides the pressure to deliver the feed water to the de-aerator or feed pump inlet. Extraction pumps are usually of the vertical shaft, two stage, centrifugal type. These pumps require a specified minimum suction head to operate and, usually, some condensate level control system in …

Stop the condensate extraction pump. 17. The CW pump may be stopped when the temperature of the exhaust part of the LP turbine falls to 328 K or to a value recommended by the manufacturer. 18. The rotor should remain on the turning gear until the temperature of the HP casing falls below a recommended limit. 19. Stop the jacking oil pump. 20.
Index Term— cavitation, condensate extraction pump, head hydraulic problems. The existence of cavitation on the loss, streamline. I.INTRODUCTION A Pump is a turbomachine which increases the energy level of fluid when fluid flow through them [1]. In the power plant system, Condensate Extraction Pump (CEP) plays an important role.
Within a thermal power plant, condensate extraction pumps are crucial to its efficient operation by optimising the steam and water loop on the turbine island.

Condensate pumps are designed specifically for the purpose of pumping liquid. As a result, if faced with the task of transporting a lower density vapor, the pump would have little effect and the vapor would not be moved. This is the problem that arises when cavitation occurs in condensate pumps.
