SRS saves money with wood

  • Follow Metro

Savannah River Site, which converted a coal-fired power plant to run on biomass fuel last year, estimates it is saving $1.5 million a year through its use of wood products.

The $10 million project begun in June 2007 included the conversion of coal-fired generators in the site's A-Area to a new system that burns wood chips and tree residue.

"It looks like a standard butler building with aluminum siding, and the program is working fine," site spokesman Jim Giusti said. "It runs on wood chips like you spread in your yard. The chips go onto a conveyor belt that flows into a boiler. The material is burned up and the ash drops out into a container."

The plant operates on 22,000 tons of wood chips each year, replacing at least 12,000 tons of coal that were used by the plant.

Some of the fuel comes from U.S. Forest Service timber operations at the site, which creates an annual yield of 35 million board feet.

Residue from timber operations is substantially cheaper than coal.

The cheaper operating costs will enable the site to pay for the new facility within 10 years.

Would have been useful to have included the megawatt size of this plant. Maybe it's top secret?!

The new plant is mostly for

The new plant is mostly for steam for heat etc. I was there for almost 20 years and all the small area plants was for steam to support the production missions.

At least this plant doesn't

At least this plant doesn't produce coal ash, which is dumped at SRS. Now, SRS has an application before SC DHEC to expand one of the dump sites. Part of SRS is run by the Forest Service as an off-the-books national forest which gets less scrutiny that a real national forest. Public input into forest management needs to be better solicited.

For every X board feet that

For every X board feet that is burned is SRS planting trees? Seems to me that it is even more wasteful if they are not; trees are renewable resources, but only if, for every tree used, two are planted in its place. No kudos there SRS--you are still wasteful!

When this type of voluntary

When this type of voluntary switch to another fuel happens, you can bet the trees are replanted. There is endless attention paid to monitor any pollutants, disease, health of workers, and etc. on the site, as well as off-site. Many household and industrial products we use today were discovered, or worked on through the DuPont contracts. If you check under the site's webpage you will see that they licence new ways to cleanup soils, waters, and about any type of contamination which exist. You are lucky to have the plant as a workplace and technology center. I do not work for the plant but I know what they stand for, "Clean everything" long before it became popular to the public.
