Abstract
Halogenated hydrocarbon materials are burned in an internally-fired horizontal fire-tube boiler and the heat of combustion directly produces saturated steam. Halogen values may be recovered from the combustion gases, e.g., by being absorbed in water. Thus halogenated hydrocarbon material which may need to be disposed of, is beneficially converted to energy and useful product.
