Circulating Fluidised Bed Combustor (CFBC) unit allows thermal destruction of organic contaminants, such as PCBs, contained in soils, sludges, solid or liquid wastes, with a removal efficiency exceeding 99.9999%. Trial burns and commercial contracts were performed with this unit. The CFBC is designed to treat from 500 to 5,000 kg/hr (1,200 to 12,000 lb/hr) of contaminated material. It comprises seven (7) modules that can be easily transported. When assembled, it occupies a surface of 20 x 25 m (65 x 82 ft) and reaches to a height of 18 m (58 ft). Plant job books and training manuals are available.
