Abstract
A method and apparatus for dehydrating sewage sludge is described. Sewage sludge is placed into a dehydration chamber. The sewage sludge is heated to convert moisture in the sewage sludge to steam and cause gasification. Steam and gases are drawn from the dehydration chamber into a condenser, where the steam is condensed to form hot water. Gases are drawn from the condenser to a burner.
