Слайд 3

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.

Слайд 4

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

Слайд 5

Economizer
The economizer is a mechanical device intended to reduce energy consumption,

or to perform another useful function like preheating fluid.

Слайд 6

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

capacity.

Слайд 7

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.

Слайд 8

Сonstruction of economizer

Boiler economizers are series of horizontal tubular

elements generally made from low-carbon steel.

Слайд 9

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.
