TVA Gallatin Fossil Power Plant
Flue gas desulphurisation

Delivered: November 2013


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
Wood powder feeding plant

Delivered: August 2013

Customer: NCC Roads asphalt plant, Hisings Kärra (Asphalt plant)

Application: Storage and feeding of wood powder for asphalt aggregate production.

The NCC Roads Hisings Kärra asphalt plant utilizes wood powder fuel in their process for heating and drying of aggregates used in asphalt production.

Tomal AB has delivered to NCC Roads AB a wood powder storage and feeding plant. The wood powder is used to fuel a burner for the drying drum in the aggregate preparation process.

A key feature of the Tomal AB system is its ability to feed wood powder to the burner at a uniform rate, without pulsations. This is essential for proper functioning of the burner and drying drum. The wood powder is reliably discharged without interruption.

The delivery includes a 250 m3; storage silo and a 4 ton/hour feeding line, about 20 MW fuel. Tomal AB provided freight, construction, electrical installation and commissioning.

To assure health and safety of the machinery operators Tomal provides CE Declaration of Conformity (2A) to EC Directive 2006/42/EC.
