TVA Gallatin Fossil Power Plant
Flue gas desulphurisation

Delivered: November 2013

Customer:


Application: Flue gas desulphurisation in a fossil fuel power plant.

The Tennessee Valley Authority (TVA) is the largest electrical power distributor in the United States, serving some 9 million customers. Their effort to reduce sulfur dioxide emissions through flue gas cleaning is a key part of a program to minimize their overall environmental impact. Tomal AB plays an important role in this program by providing equipment for reliable and accurate feeding of lime used to remove sulfur dioxide (SO2) in an Alstom Power flue gas desulphurisation system.

Tomal AB, in partnership with Prominent Fluid Controls, Inc. USA, has delivered eight “twin” multiscrew feeders that supply sixteen lime dosing lines. The accuracy and reliability of Tomal feeders help to ensure that up to 98% of SO2 is removed while maintaining lower lifecycle costs than competing types of desulphurisation systems.



C4 Energi, Allöverket
Sulphur feeding plant

Delivered: October 2013

Customer: C4 Energi AB, Kristianstad, Sweden


Application: Big Bag feeding station with two sulphur feeding lines for corrosion prevention.

 C4 Energi, Allöverket is a power and district heating plant that utilizes 99% renewable fuel. This matches the environmental goals of Kristianstad Municipality to be “fossil free”. The fuel consists mainly of wood chips but also bio-gas and bio-oil.

Burning of bio-fuel often exacerbates corrosion in the furnace, mainly in the superheaters, due to the low sulphur content fuel. To reduce corrosion and clogging in the superheaters a small amount of sulphur is added to the fuel intake.

An important side effect is that combustibility increases resulting in lower CO emissions. By decreasing the amount of O2 you can reduce NOx emissions as well.

Equipment delivered includes:

  • Big bag emptier with hoist.
  • Dust-free connection of the big bag.
  • Buffer hopper 500 dm3.
  • Two feeding systems. Capacity 2 × 0.5 − 3.5 kg/h.
  • Two pneumatic conveying systems.
  • Conveying hoses with wear detection.
  • Machine room.
  • Commissioning.
  • ATEX CE Declaration of Conformity to ATEX directive 94/9/EG.
  • CE Declaration of Conformity (2A) to Machine Directive 2006/42/EC.



NCC Kärra
