Slide 2

Introduction Steam generators, or boilers use heat to convert water into steam for variety of applications. Steam is widely used on thermal power plants to produce electricity.


Slide 3

Steam generator components The major components in the steam generating and heat recovery system are the following: Furnace steam superheaters steam reheater economizer steam drum air heater


Slide 4

Economizer The economizer is a mechanical device intended to reduce energy consumption, or to perform another useful function like preheating fluid.


Slide 5

Advantages of economizer Fuel economy; Longer life of the boiler; Increase in steaming capacity.


Slide 6

Boiler economizer In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid.


Slide 7

Сonstruction of economizer Boiler economizers are series of horizontal tubular elements generally made from low-carbon steel.


Slide 8

Conclusion The common application of economizers in steam power plants is to capture the waste heat from boiler stack gases and transfer it to the boiler feedwater.
