Alimak rack and pinion elevators for power plant FGD systems

An Alimak SE-H rack and pinion elevator was installed to provide vertical access for frequent upkeep and maintenance of a flue gas desulfurization system at a power plant near New Haven, WA, USA. 

The large capacity elevator ensures the plant can stay on top of the maintenance, without the need for a crane. 

The AEP Mountaineer Power Plant is a coal-fired, 1300 megawatt generating facility located near New Haven, West Virginia. To achieve this output of electricity AEP Mountaineer burns an average of 9,000 tons to 12,000 tons of coal a day. AEP has added to this plant state of the art emission control equipment. One piece of this system is a flue gas desulfurization (FGD) system. FGD systems, commonly known as “scrubbers”, will help keep the plant in compliance with environmental regulations by reducing the sulfur dioxide emissions. The FGD building is running constantly and it requires frequent upkeep and maintenance. The plant decided they needed a large capacity elevator to stay on top of the maintenance, without the need for a crane. AEP Mountaineer chose an Alimak SE-H 2700 rack and pinion elevator with a 2,700 kg capacity (near 6000 lb). By installing a large permanent elevator on the FGD building they can get personnel plus their heavy tools, large equipment and specialized parts to the top of the FGD building at any moment. This may minimize unplanned outages if the scrubber goes down because they can start repair work instantly. Alimak rack and pinion elevators can be placed in environments where traditional traction elevators cannot, for several reasons: 

  • Alimak elevator can be installed onto the existing structure in a number of places because it requires no hoist way or machine room 
  • It is vertically self-supporting and imposes only relatively small tie-in loads on the existing structure 
  • The elevator can be installed inside or outside, with or without a below grade pit 
  • Alimak’s rugged, industrial grade elevators 
  • come in many sizes and capacities and can be tailored to fit in nearly any situation 

Alimak, with an extensive line of elevator and hoist products, and mast climbing work and transport platforms has been the world leader in rack and pinion driven vertical access solutions for over 50 years. Elevators and hoists from Alimak have been installed in numerous power plants worldwide on a variety of structures.
