Thermal Power Plant : Principle, Parts, Working, Advantages and Disadvantages

Basic Introduction or Principle: We all are aware with the term "Generator". A device which converts mechanical energy into electrical energy is known as generator. This generator makes rotate with the help of some kind of external energy. When this energy extract from the energy of steam, the plant is known as steam power plant.  A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a  boiler   which converts it into high pressurized super heated steam. This high energized steam passes through steam  turbine  (a mechanical device which converts flow energy of fluid into mechanical energy) and rotate it. Owing to extract full energy of steam, three stage turbines is used which is known as LPT (Low pressure turbine), IPT (intermediate pressure turbine) and HPT (High pressure turbine). The turbine shaft is connected to the...

How Many Types of Boilers?

Today we will discuss about types of boilers used in industries. A boiler may be defined as a closed vessel in which steam is produced from water by combustion of fuel. Boiler is used in many industries such as in steam power generation, in sugar industries, in textile industries for sizing and bleaching etc. and in many other chemical industries. Earlier it was mainly used in  power  generation  in steam engine.  Boiler is also known as steam generator. The primary requirement of boilers is the water, which must be contained safely and the steam must be safely delivered in desired condition.  In a boiler, many parts and fittings of mounted, which are mounted on the boiler for its proper and safe functioning. These are as follow 1. Water level indicator 2. Pressure gauge 3. Safety valves 4. Stop valve 5. Blow of cock 6. Feed check valve 7. Fusible plug Types of boilers: Boiler may be classified in following types. According to the ax...

Benson Boiller : Principle, Construction & Working

Today we will discuss about Benson boiler. Benson boiler is also known as super critical steam generator which is developed by Mark Benson in the year 1922. This boiler can generate high pressure steam, which is further used in production of electricity and other industrial processes. It is a water tube boiler. In the early stage water tube boiler used to generate steam at the pressure up to 10MPa, which is known as sub critical boiler. Two big problem occur in sub-critical boiler. 1. First, in sub critical boiler water form the vapor bubbles at the tube surface, which decrease heat transfer rate, hence decrease efficiency. 2. The second one is, the sub critical boiler used the water steam separator drum to separate steam which make it too complex and heavy. It cannot be easily transfer from one station to another. To overcome these problems, in 1922, Mark Benson invent...
