Vacuum Pump Rotary Pump Diffusion Pump Molecular Pump

The pump utilized to create a vacuum inside a closed container is called a vacuum pump. Absolute vacuum cannot be created, hence the degree of vacuum comes into picture when we discuss a vacuum pump. Any vacuum pump has three main features. Exhaust Pressure Degree of Vacuum Pumping Speed. Exhaust Pressure of a Vacuum Pump … Read more

Thermal Power Generation Plant or Thermal Power Station

Thermal power generation plant or thermal power station is the most conventional source of electric power. Thermal power plant is also referred as coal thermal power plant and steam turbine power plant. Before going into detail of this topic, we will try to understand the line diagram of electric power generation plant. Theory of Thermal … Read more

Wind Energy Electricity Generation

Wind energy simply means kinetic energy of air in motion. Air flows on the earth due to uneven heating of the earth surface by radiant energy from the sun. There are many places on the earth where the wind always presents. As the wind is naturally available mechanical energy, we can use this wind to … Read more

Natural Draught and Chimney

Draught is the pressure difference which causes a flow of air or gases from one point to another point in the boiler system. Draught is required in a boiler system mainly due to two reasons. To supply sufficient air for completing the combustion. To remove flue gases from the system after combustion and the heat … Read more

Types and Working of Cooling Tower

Purpose of a cooling tower is to reduce the temperature of circulating hot water to re-use this water again in the boiler. This hot water is coming from the condenser. How Cooling Tower Works? Hot water is coming at the inlet of the tower and pumped up to the header. The header contains nozzles and … Read more

Schematic Diagram of Gas Turbine Power Plant

The main components of a gas turbine power plant are the compressor, regenerator, combustion chamber, gas turbine, alternator, and starting motor. Compressor Air compressor used in a gas turbine power plant is mainly of the rotary type. The air filter is attached at the inlet of the compressor where air gets filtered from dust. The … Read more

Natural Draft Cooling Towers

A cooling tower is an open direct contact type heat exchanger where hot water from system or condenser gets cooled by direct contact with fresh air. Cooling towers use the principle of evaporation of water against the air flow. Hot water is sprayed from the nozzles for increasing the heat transfer surface area. The temperature … Read more

Steam Jet Draught

The boiler produces steam. If we utilize, a small portion of the pressurized steam for producing draught in a boiler system then we call the draught as steam jet draught. As the steam, causes the draught, generated in the boiler itself, there will be no need for extra electric power to run draught fans. Steam … Read more

Pulverized Fuel Firing of Boiler

The solid-fuel firing method is inefficient to take care properly the fluctuations of the load. There is a limitation in the combustion process. Solid-fuel firing method is not stable hence not suitable for large capacity thermal power plants. The flue gases contain a large quantity of ash, and for large capacity boiler, it is difficult … Read more

Unit of Electrical Energy

The unit of electric power is watt, and hence unit of electrical energy is watt – second since energy is the product of power and time. The watt – seconds is referred as joules. One joule means the work required to be done for transferring one-ampere current in one second from one point to another … Read more
