| 20090035211 | DEVICE FOR ENERGETICALLY UTILIZING SOLID WASTE - The invention relates to a device for energetically utilizing solid waste. The term “solid waste” refers, for example, to waste paper, scrap wood, plastic waste, production waste, industrial sludge or other solid fractions containing combustible constituents, or mixtures thereof. The aim of the invention is to create a device for thermally utilizing solid waste, which has a neutral if not even positive energy balance and is suitable for a wide range of waste materials while paying special attention to environmental relevance, especially the flue-gas composition. The aim is achieved by providing the inventive device with a material-feed mechanism, a charring apparatus and a thermal post-combustion apparatus. These basic components make it possible to utilize many different types of solid waste, the feedstock initially being transformed into hot gas which can be converted into steam and power as required. | 02-05-2009 |

| 20140112859 | METHOD FOR PRODUCING CARBONACEOUS FILM, METHOD FOR PRODUCING GRAPHITE FILM, ROLL OF POLYMER FILM, AND ROLL OF CARBONACEOUS FILM - Disclosed herein is a method for producing an elongated (rolled) carbonaceous film by polymer pyrolysis while suppressing the fusion bonding and the rippling of the carbonaceous film. The method for producing a carbonaceous film includes the step of heat-treating a polymer film wound into a roll, wherein the heat treatment is performed after the polymer film is wound into a roll at a temperature lower than a pyrolysis onset temperature of the polymer film so that the roll of polymer film has a center and has a space inside its cross-sectional circle (50% cross-sectional circle) (space within 50% cross-sectional circle) whose center is at the center and whose circumference passes through a point at which a length of the polymer film from an inner end thereof is 50% of a total length of the polymer film and that an area of the space within 50% cross-sectional circle is 25% or more of an area of the 50% cross-sectional circle. Particularly, providing a space between a core and an innermost layer of the roll of polymer film is more effective at solving the above problem. | 04-24-2014 |
