power plant economizer

,

economizer for boiler

Spiral type boiler economizer super cirtical coal fired plant high temperature high pressure

 

Spiral Finned Tube Economizer

 

1.The economizer can be installed at the rear of exhaust gas stovepipe to recovery exhaust gas heat,increase the electricity output,lower the coal consumption.spiral finned tube 2.economizer is a new and efficient heat transfer equipment, which is a good solution to the light tube economizer because of badly worn, short life and other shortcomings.

 

Details

 

1.Heat transfer area can be greatly extended, reducing the volume and angle fittings, enhanced heat transfer.

2.As gas flows through the finned tube forming the boundary layer, resulting in the vortex.Adapting to wide temperature, high pressure;impact resistance low flue gas resistance.

Purpose

 

1.Using an economizer does not just prevent heat loss — it can also extend the life of the boiler.

2.Stresses from using cooler temperature make-up water, known as “thermal shock”, can subject wear and tear on the boiler’s structural integrity over time.

3.This hammering “shock” effect occurs as the boiler’s fixed tube-sheets and fire-tubes rapidly contract from the sudden make-up of cooler temperature water.

4.However, when this water is pre-heated, the temperature differential is far less extreme, putting less strain on the boiler and giving it a longer operating life.

 

Advantages

 

1. The equipment body can be designed into many modules to ensure the long term and stable running;

2. The low temperature economizer manufactured by our company can guarantee the wall temperature is 5-10 ℃ higher than the acid , and flue outlet temperature is 10-15 ℃ higher than the wall surface temperature

3. Wall surface temperature can be adjusted according to the boiler load and fuel changer to avoid corrosion under low temperature

4. Changer the DCS system of the existing boiler to achieve the auto and remote control by computer.
