Refuse derived fuels for the cement and lime industry

Development of a hot filter for energogas made by gasification of refused derived fuel (rdf). This hot filter will clean the energogas from high molecular pyrolysis products, sulphur, chlorine and fluorine compounds.

There is an interest of many companies that produce lime and cement in the possibility of using Refuse Derived Fuel (RDF) as a substitute for conventionally used fuels. RDF is basically sorted industrial waste. It includes papers, plastics, leathers, wood and textiles. RDF can be either burned directly in a burner or gasified and used as a gas fuel. The big advantage of RDF gasifying is the transformation of RDF energy fixed to solid phase to another chemical energy fixed to gas phase. This factor makes it possible to use energogas in kilns where it is impossible to use solid RDF directly in the burner (lime kilns, white cement kilns, etc.). RDF contains some sulphur, chlorine and fluorine compounds. They remain partly in the reactor ash as inorganic mineral salts and, in energogas, partly as hydrogen chloride, fluoride, sulphide, PCB and PCDD/F. The objective of the project is to develop a hot filter for energogas made by the gasification of RDF. This hot filter will clean the energogas from high-molecular pyrolysis products, sulphur, chlorine and fluorine compounds. The limestone will be used as a filter bed material. This is a very simple and cheap solution for using this technology of natural gas substitution in the cement and lime industry. Keywords: energogas cleaning, gasification, Refuse Derived Fuel (RDF).
