Understanding Steam Power Plants: Components and Operation

Steam Power Plant

AUWh7SUY1A4FAAAAAElFTkSuQmCC

  • The major components of this power plant are: (i) boiler, (ii) steam turbine, (iii) condenser, (iv) water feed pump, (v) electrical generator, (vi) cooling tower, etc.
  • In a steam power plant, thermal energy is converted to electric energy.
  • Water is supplied to the boiler through a feed water pump (1) from the water tank.
  • The water in the boiler (4) is heated by transferring heat from the combustion of fossil fuel in the furnace. The boiler consists of an economizer (6) and a superheater

Types and Functions of Mechanical Couplings and Clutches

Understanding Mechanical Couplings

Durable Couplings are essential machine components used during power transmission. Their primary functions involve connecting shafts, facilitating mounting, and simplifying maintenance.

Drive Couplings

These couplings provide a direct link between two shafts, typically transmitting rotational motion. They often involve plates or screws connecting the elements, allowing for power transfer but generally not accommodating misalignment unless specifically designed to

Fire Protection Systems in Buildings

Fire Extinguishing Installations

BIE (Fire Hose Stations)

A pressurized water fire extinguishing system comprising:

  • Connection to a public water supply or fire pumping equipment.
  • Network of pipes for water distribution.
  • Hose reel (BIE).

Sprinklers

Individual, automatic sprinkler heads connected to a separate cold water pipe, capable of withstanding a pressure of at least 150 meters of water column (mca), and composed of:

CT Installation: Components, Classifications, and Features

CT installation is provided with one or more processors, reducing high and low voltage switchgear and working with precise complementary functions. The function of a CT is to distribute electricity to different voltages while simultaneously allowing the connection to lines and networks at any point. CTs are classified in five ways:

Classification by Food (Supply)

  • In Point: There is only one supply line connected to the derivation of the main network.
  • In Step: Has one input and one output line to another
