Burning coal's waste
In an old Pennsylvania coal valley, growing fresh produce and eliminating ancient waste piles both depend on a fluidized bed boiler cogeneration plant. The builders of a complex now nearing completion at Archbald, however, will soon begin to turn two of the waste piles, called culm banks, into economic assets. Culm will burn although it has a low, variable heat content. The project combines several recently developed technologies to use culm as fuel for a fluidized bed boiler cogeneration plant that will heat a hydroponic greenhouse. What makes the venture economically viable are the products that will be sold: 23 mw of electricity to the local utility and fresh produce to meet burgeoning demands in East Coast supermarkets. For instance, if the ''salad plant'' were completely devoted to growing lettuce, 3 million heads could be harvested in 11 hydroponic seasons a year. The owners, Archbald Power Corp., chose a 271 acre stie that had been mined for anthracite by both open pit and deep shaft methods.
