In a steam cycle, the water is heated to steam (usually superheated steam) in a boiler. The steam then runs a turbine which is connected to a generator to create electricity. After the steam passes thru the High Pressure Turbine and the Low Pressure Turbine, it's heat energy is used to preheat the feed water.

The power plant has two (each at 50% of total steam) boiler /incinerator units each producing 65,800 Ib/hr of steam, in which whole automobile and truck tires are fed through the tire feed system. The heat resulting from tire incineration is used to generate steam that in turn drives a single condensing steam turbine-generator.
In this article we will study about the construction,working, efficiency, advantages and disadvantages of steam power plant. Steam Power Plant. It is the power plant which is used to generate electricity by the use steam turbine. The major components of this power plant are boiler, steam turbine, condenser and water feed pump.

We prepared an article on Power Plant Interview Questions & Answers which covers basics about power plant operation. Name the four major circuits in steam power plant. Feed water and steam circuit. What consists of air and flue gas circuit? Air and flue gas circuit consists of forced draught fan, air pre heater, boiler, furnace, super heater
available as fuel for the refinery power boilers and steam generators has decreased dra-matically, presenting boiler and firing systems designers with significant challenges. The lowest quality streams can have a variety of names based on the specific refining process from which they are generated, but can be generally referred to as asphalts.
systems, steam losses, evaporation from cooling, and blowdown. • Since there is a constant loss of cycle water for one reason or another, it is always necessary to have a continual source of incoming water. • Treating this water is the beginning of the power plant's cycle chemistry. • Makeup treatment almost always consists of
Reheat steam pressures are normally around 45 bar. SuperHeater / ReHeater. The above are the major water and steam circuit items in a boiler and are collectively called the 'pressure parts'. This post is part of the series: Working Of A Power Plant Boiler. Boiler in a power plant has two functions.
The heat produced converts water, which runs through a series of pipes in the boiler, to steam. The high-pressure steam turns the blades of a turbine, which is connected by a shaft to a generator. The generator spins and produces electricity. A Coal-Fired Thermoelectric Power Plant .
The power plant's control system can use the high pressure differential measurement to automatically set the feedwater rate depending on the boiler load demand. At lower demand periods, less steam is used to power the steam turbine driven pump and less feedwater is consumed.
Steam Superheaters in Industrial Boilers. The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the
The natural gas boiler produces high pressure steam to generate about one-third of the 35 MMgy plant's electrical needs, then the lower pressure steam goes on to supply the plant's process heat. "We save $15,000 a month in electrical bills," says Doug Sommer, EKAE plant manager.
1. Condensate or condensed steam returned from the processes. 2. Makeup water which is the raw water which must come from outside the boiler room and plant processes. The steam system collects and controls the steam produced in the boiler. Steam is directed through a piping system to the point of use.
Schematic diagram of a steam power plant. High-pressure steam leaves the boiler and enters the turbine. The steam expands in the turbine and does work which enables the turbine to drive the electric generator. The exhaust steam leaves the turbine and enters the condenser where heat is transferred from the steam to cooling water.
When steam from the distribution system enters the steam using equipment the steam will again give up energy by: a) warming up the equipment and b) continuing to transfer heat to the process. As steam loses heat, it turns back into water. Inevitably the steam begins to do this as soon as it leaves the boiler. The water which forms is known as
•Steam cycle - Begins at the boiler where thermal energy in superheated steam is converted to mechanical energy in the propulsion turbine - Steam is then converted into condensate in the main condenser - Condensate is combined with distilled makeup water and is pumped as feedwater through heaters to a
Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
steam from the oil-fired straight watertube boilers. The Medea's steam engine and boiler, although built six years later, are typical of the previous generation of steam plants, the two-cylindered compound double-expansion engine supplied with steam from a firetube boiler, originally burning coal but since converted to oil.

Heat Transfer In Steam Boiler. A steam boiler is designed to absorb the maximum amount of heat released from the process of combustion. There are three way (Radiation, convection & Conduction) that heat is transfer in the boiler and relative percentage of each heat transfer within system boiler is dependent on the type of steam boiler, fuels and the designed transfer surface.
This is the pump for sending high pressure and high temperature fluid to the boiler. The types vary depending upon the pressure. The single casing type is used for the combined cycle, the subcritical steam power generation, etc.

Boilers are defined as "Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.
Boiler, apparatus designed to convert a liquid to vapour. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect. A conventional boiler has a f
Boiler or more specifically steam boiler is an essential part of thermal power plant. Steam boiler or simply a boiler is basically a closed vessel into which water is heated until the water is converted into steam at required pressure. This is most basic definition of boiler. The basic working principle of boiler is very very simple and easy to
Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 22.214.171.124 Requirements of Condensate Polishing Unit. Boiler pressure is the key factor for determining the requirement of a CPU system (see Figure II/3.6.6-1).For the steam generator plant with low steam pressure (below 40 kg/cm 2), the requirement of a condensate polishing unit is usually avoided.
