The following is a record of factors that affect the selection of a site for building a Steam power station:. Supply of fuel:
Coal and Ash circuit Pulverised coal from the storage area (called stack) is taken to the boiler by means of coal handling equipment such as belt conveyors, bucket elevators etc. Note : A thermal power plant of 400 MW capacity requires 5000 to 6000 tonnes of coal per day. After the pulverised coal is burnt at 15000C to 20000C by combustion it
This is the multi-stage pump having the double casing, the inner casing contained in the outer casing. Among various boiler feed water pumps, this pump is adopted for high pressure and high temperature application as in the subcritial steam power generation.
A steam power station is described in the figure 3. The boiler volume is 50 L and it contains 90% liquid and 10% steam (volume fractions) at 100 kPa. When the pressure in the boiler reaches 700 kPa. The pressure valve starts to work and maintains constant pressure in the boiler of 700 kPa.
A combined cycle power plant (CCPP) is a complex system with a Gas Turbine, Steam Turbine and a Heat Recovery Steam Generator (HRSG) working together. The HRSG is a key component of a combined cycle power plant. Its role is to convert as much of the heat as possible from the exhaust gas of the gas turbine into steam for a steam turbine.
Running large steam boilers had proved to be dangerous. With so much water in such volume, defects in materials or workmanship could cause a boiler to explode at high pressure. In 1922, Mark Benson was granted a patent on a boiler for converting water to steam at high pressure.

Inside the furnace, combustion
The capital cost for a greenfield steam and power plant is high and may not be justifiable. As a result, existing infrastructure should be utilized wherever possible. Since the boiler is the largest capital cost, one should evaluate modifying an existing boiler to accept syngas to replace natural gas or fuel oil.
A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.

Although boilers can be small, most of the boilers in power-generation are very large, requiring hundreds of people in varying shifts to build the scaffolding. Boilers consists of four primary areas and shapes that every scaffolder needs to be aware of: the base, the main birdcage structure, the bullnose, and the superheater.
Eventually, the plant must initiate a rundown or reduction in steam generation rather than trip the boiler. Typical rundowns are associated with air flow, furnace pressure, fuel flow, feedwater
If the plant has only one steam generator (boiler), uses a single fuel, and has a single steam pressure level, it is relatively easy to assign a cost to the steam. However, in most cases, there are multiple steam sources and multiple fuels. There are also multiple steam pressure levels with multiple
