The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical it passes through the turbine, the steam is condensed in a greatest variation in the design of steam-electric power plants is due to the different fuel sources. Section 4. Technology Characterization – Steam Turbines. Introduction. Steam turbines are one of the most versatile and oldest prime mover technologies still in general production used to drive a generator or mechanical machinery. The first steam turbine used for power generation was invented in .
TYPES OF THERMAL POWER PLANT: 1. Condensing Type Thermal Power Plant: In Condensing type thermal power plant, discharges exhaust steam is coming to a condenser which creates suction at very low pressure and it allows the expansion of steam in the turbine to a very low a result, turbine's efficiency increases. This type of thermal power plant plays an important role where there is . Direct air-cooled condenser units in power plants usually consist of finned tubes arranged in the form of ground surface area. A-frame direct air-cooled steam condenser units are normally arranged in multi-row or multistreet arrays.

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. steam must have appropriate temperature and pressure which must be controlled during start-up. Prior to supplying steam to the turbine, the steam supply pipelines have to be drained and heated up. In case of turbines with cooling water preheating and low-pressure (LP) by-pass, prior to supplying steam the regeneration and dumping systems have to be.

Heat Exchange Institute (HEI), Standards for Steam Surface Condenser, AIR COOLER SECTION. The condenser tubes and baffles are arranged in such a way as to cause the steam to flow from the condenser steam inlet toward the air cooler section.
The steam carries with it the noncondensible gases such as air, carbon. The condensing steam turbine in general use for power production employs a fuel which may be oil, coal, gas or nuclear power, to heat water to a temperature close to the critical point. Most modern power stations operate at a steam feed temperature of between and °C and a steam pressure.

Therefore, the complete steam plant consists of a furnace in which to burn the fuel, the boiler in which the heat from the furnace is used to boil water into steam, the steam engine which turns the heat of the steam into mechanical power, the condenser which condenses the steam back into water, and the feed pump that pumps the waterFile Size: 2MB.
20 rows Condensers for Steam Power Plants; And over the past 35 years, we have retrofitted. Identifying the Steam-Condenser Problem • A successful air-cooled steam condenser must continuously and completely gather and discharge all of the noncondensables in the system.
• These are the gases that result from atmospheric air leaks into the vacuum portions of the steam. Interest in the use of an air cooled condenser (dry cooling tower) in steam power plants has increased due to concern about the amount of water required for a conventional steam power plant with once through cooling or a wet cooling tower.
Steam Power Plant water cooling to condense the low pressure steam exhaust from the turbine is a crucial part of the Rankine power cycle typically used in a.
In these condenser the process is used sufficient boiler feed water is available. Where as in these process sufficient boiler feed water is not available and the condensed steam is reused as boiler feed water. The condensing plant is economical and simple. The condensing plant is costly and complicated.
process is very cheaper. A steam condenser is a closed vessel in which vacuum is maintained and the exhausted steam is condensed by extraction of heat. About 50% to 60% of the heat energy associated with steam is lost in a steam condenser. Cooling water supplied to the condenser for the condensation of steam.
The subject of this chapter is the capital equipment in a steam power plant that is used to condense the exhaust steam from the lowest pressure turbine, by using water as the cooling medium. In the applied heat transfer literature, such heat transfer equipment is often simply referred to as the “Surface Condenser.”.
Steam Power Plants power plants, power is generated by alternately vaporizing and condensing a working ﬂ uid (in many cases water, although refrigerants such as ammonia may also be used) .
There are four processes in the Rankine cycle, each changing the state of the working ﬂ uid. These states are identiﬁ ed by number in Fig. Steam power plants cycles Rankine cycles describe the operation of steam heat engines commonly found in power generation plants as schematically shown here in Figure 1.
In such vapor power plants, power is generated by alternately vaporizing and condensing a working fluid (in many cases water, although refrigerants such as ammonia may also be. Page - chambers, including ash carried away in the gases, if any, determined from the analyses of coal and ash.
The "combustible" used for determining the calorific value is the weight of coal less the moisture and ash found by analysis. The "heat absorbed" per pound of coal, or combustible, is calculated by multiplying the equivalent evaporation from and at degrees per pound Reviews: 1.

Condenser: It is a closed vessel used to condense the steam. The low pressure steam gives off its heat to the coolant (here water from cooling tower) and gets converted into water during the process of condensation.
Elements of a Steam Condensing Plant The main elements of a steam condensing plant are: a condenser in which the exhaust steam in condensed, — supply of cooling or injection water, for condensing exhaust steam, — a pump to circulate the cooling water in case of a surface condenser.

The primary type of steam turbine is the condensing steam turbine, which has been used for large drive applications above a certain power rating limit (say, as a very rough indication, above 8 MW). These steam turbines exhaust directly to one or more condensers that maintain vacuum conditions at the discharge of the steam turbine.C H A P T E R T W O Fundamentals of Steam Power Introduction Much of the electricity used in the United States is produced in steam power plants.
