MAIN COMPONENTS BOILER TURBINE DEAERATOR HEAT EXCHANGERS SUPER HEATER ECONOMIZERS CONDENSOR FEED WATER HEATER

BOILER :

BOILER The boiler is also termed as, ‘ steam generator generator’ ’ is a container in which water can be fed and by the application of heat evaporated continuously into steam.The heat source is obtained by burning the fuel, which is coal.Water circulates in the water walls the heat energy is applied to the water walls and water converted into steam,this steam is fed into upper heaters to remove water particles to obtained superheated steam is fed into superheater where water particles is completely removed & finally fed to turbine.

A. Boiler Systems

Slide 6:

2. Water tube or "water in tube" boilers in which the conditions are reversed with the water passing through the tubes and the hot gasses passing outside the tubes. Two categories of boiler: Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates.

Slide 7:

2. Turbine Turbine , rotary engine that converts the energy of a moving stream of water, steam, or gas into mechanical energy. The basic element in a turbine is a wheel or rotor This mechanical energy is then transferred through a drive shaft to operate a machine. Turbines are classified as hydraulic, or water, turbines, steam turbines, or gas turbines .

It also combines with any dissolved carbon dioxide to form carbonic acid. Most deaerators are designed to remove oxygen down to levels of 7 ppb by weight (0.0005 cm³/L) or less. 3. Deaerator

4. Heat Exchangers

Slide 10:

3. Deaerator A deaerator is a device that is widely used for the removal of air and other dissolved gases from the feed water to steam generating boilers In particular, dissolved oxygen in boiler feedwaters will cause serious It also combines with any dissolved carbon dioxide to form carbonic acid. Most deaerators are designed to remove oxygen down to levels of 7 ppb by weight (0.0005 cm³/L) or less.

5. Super Heater Super heater are meant to raise temp. of steam,the saturation temp.by absorbing heat from flue gases limiting the value the boiler is 540 540drg.drg.c. super heater eliminate the formulation of condensate during transporting of steam in pipe lines & inside the early stage of the turbine which is harmful for turbine blades.

7. Economizers

Slide 13:

6. Condenser

Slide 14:

8. Feed water heater

Slide 15:

Air preheater is a heat exchanger in which air temp. raised by transferring heat from other fluid such as flue gases.Since air heater cab be successfully employed to reclaim heat from flue gas at lower temp. level,thus heat ejected to chimney is reduced, hence boiler efficiency is increased AIR PREHEATER
