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.
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
Economizer The economizer is a mechanical device intended to reduce energy consumption, or to perform another useful function like preheating fluid.
Advantages of economizer Fuel economy ; Longer life of the boiler ; Increase in steaming capacity.
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.
С onstruction of economizer Boiler economizers are series of horizontal tubular elements generally made from low- carbon steel.
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.
