TOP DIFFUSOR

Fossil-fueled power stations around the globe are under increasing pressure to operate with maximum efficiency and minimum emissions.

A power station built in 2020 is significantly more efficient, economically as well as environmentally, than a power plant built in earlier years. In spite of these technical improvements, power plant chimneys today are essentially the same as forty years ago, except for the fact that different construction materials are used for the internal flues.

Hadek has developed a range of innovative technologies and concepts for new power plant chimney construction and chimney modernization. On this page, we present the Top Diffusor^TM.

COMPLICATIONS OF FGD WET STACK OPERATIONS

One of the complications of using FGD Wet Stack is, that the flue gas temperature in such chimneys is low, which will result in reduced draft as well as positive pressure, especially for power stations operating in hot climates.

INNOVATIVE TECHNOLOGY: TOP DIFFUSOR

In cooperation with German design specialist Constructure, Hadek has developed a specific diffusor that is to be placed at the top of an NCD (New Chimney Design) chimney, which has a height of 15 meters and runs outward under an angle of 8 degrees. The use of this Top Diffusor will increase the draft in the chimney by 60%, while also preventing the problem of damaging positive pressure.

The proposed Top Diffusor (patent pending) could be constructed as part of the normal slip forming process and its limited additional cost would typically be earned back within 5 years.

ADVANTAGES OF THE NEW TOP DIFFUSOR

Including a Top Diffusor in your power plant chimney design significantly reduces operating and maintenance costs. Moreover, emissions are significantly reduced, and the risk of harmful stack liquid discharge ("spitting") is minimized.

For additional cost and emissions reduction, power plant owners may consider our other innovative ideas:
