Why do we create a vacuum in a steam turbine

Question: Why do we create a vacuum in a steam turbine condenser? Let me take two minutes to explain from rankine cycle. It is known that "The Rankine cycle" is the fundamental operating cycle of all thermal power plants where an operating fluid i

Steam Condenser: Types, Working Principle,

The air extraction pump extracts air from the condenser and produces a vacuum inside it. The vacuum produced helps in the circulation of cooling water and the flow of condensate downstream. Types of Steam Condenser. Following are the two main types of steam condenser: Jet condensers (mixing type condensers) Parallel flow jet condenser

Condenser vacuum system - Vacuum Pump - EVP

The air ejector condenser also preheats the condensate returning to the boiler. Two-stage air ejectors are capable of drawing vacuums to 29 inches Hg. A vacuum pump may be any type of motor-driven air compressor. Its suction is attached to the condenser, and it discharges to the atmosphere. A common type uses rotating vanes in an elliptical

Troubleshooting Steam Surface Condensers

2012-9-15 · Condenser Vacuum Pumps Condensers are provided with vacuum pumps/ejectors The condenser creates the vacuum, NOT the vacuum pump Vacuum pumps are there to extract air and pump it up to atmospheric pressure A startup ejector ("hogger") is provided to create a rough vacuum in order to start the turbine Condenser Venting

Size Vacuum Boiler Feed - MathWizard™ - Shipco®

Vacuum Air Producer Sizing. Vacuum Air Producer Size is determined from TOTAL system load given for Boiler Feed Pump Receiver Size. If system is new, load is calculated based on 0.5 cubic feet of air removed per minute (CFM) for each 1000 square feet EDR.

Barometric Condensers | Schutte & Koerting

Fig. 594 Multi-Spray Barometric Condenser was developed primarily to solve condensing problems where water supply is limited, it is also well suited in operations where water temperatures are high in relation to vacuum requirements, or where a large volume of non-condensables must be removed. Vapor enters the condenser at the top and is thoroughly mixed with injection water which is delivered

Condensing steam locomotive - Wikipedia

2020-12-15 · Thermodynamics. Unlike the surface condenser often used on a steam turbine or marine steam engine, the condensing apparatus on a steam locomotive does not normally increase the power output, rather it decreases due to a reduction of airflow to the firebox that heats the steam boiler.In fact it may reduce it considerably. Condensing the steam from a high volume gas to a low volume liquid

Why vacuum may be lost or not maintained in steam

2. The noncondensate (air) can be removed from the condensate-steam circuit by pulling and maintaining a vacuum in the steam side. Therefore, the condensate can be used as boiler feed. Ideal conditions of surface condenser used for steam power plants 1. Uniform distribution of exhaust steam throughout to the heat transfer surface of the

TSPS Engineering Manual -

2019-4-15 · The Nash Vacuum pump was installed in 1991, and is representative of equipment found on modern merchant ships. The purpose of the vacuum pump is to create and maintain the vacuum on the main condenser, and it can be used as a back-up and alternative to the main air ejectors. The vacuum pump has two-stage rotor which is turned by an external motor.

Condensers: Necessity, Classification, Sources of Air

2020-12-17 · If the condenser temperature is known, P s is found from steam tables and P c can be read from the vacuum gauge. ∴ We can write, P a = P c – P s Knowing the partial pressure of air P a its mass m a can now be calculated with the help of ideal gas equation P a V c = m a RT a where V c = volume of condenser; T a = temperature; R

(PDF) Steam Condenser - ResearchGate

The vacuum eff iciency is a measure of the degree of perfection in achieving the desired vacuum in the condenser. The vacuum efficiency may be defined as the ratio of actual vacuum as recorded b y

Air-cooled vacuum steam condenser - LARINOFF;

An improved air-cooled vacuum steam condenser in a steam turbine cycle comprising a turbine for generating mechanical power, a boiler for generating steam, a conduit arrangement coupling the boiler to the turbine and then another conduit arrangement coupling the turbine exhaust back to the boiler through steam condensing mechanism.

Air Cooling in Steam Plant Condenser Using

2018-7-17 · Modifying the steam plant condenser by incorporating a vapor compression refrigeration system, which is utilized to chill the water used for cooling the condenser air cooler, is proposed in this work. Hence a considerable drop in air temperature is obtained, and more steam associated with air is condensed resulting in reducing both steam lost and vacuum pump power.

What is Boiler and Condenser Pressure - Rankine

Boiler and Condenser Pressures. The thermal efficiency of steam turbine tends to increase as the average steam pressure increases and/or the condenser pressure decreases. Thermal Engineering

gas fired condensing vacuum hot water boiler

Condensing boiler technology is the latest face of boiler innovation, with typical efficiencies greater than 90% and significant energy savings. Condensing hot water boilers recover the waste heat in the flue gases and use it to pre-heat the cold water entering the boiler. GET PRICE BY E-MAIL Industrial Biomass Fired Vacuum Boil. Get a Quote

Why We Maintain Small Vacuum In Atmosphere

The first condenser output is then a cool dried air while the other one give portable water. Thus an atmosphere condenser is nothing but an air cooled condenser with fins attached; to successfully radiate heat out of the system. It is also used in power plant and boiler system in areas with water scarcity. Why Vacuum is Maintained in Most


2020-12-7 · RESIN BEHIND DROPPING CONDENSER VACUUM. In this article, we discussed the causes of dropping condenser vacuum during a running time of turbine and also when we started the steam turbine The main signals of the condenser vacuum reduction during turbine running are: temperature rise at the exhaust cylinder; reduction at the vacuum meter and obvious terminal difference of the condenser.
