Method and installation for conversion into fuel of organic material originating for instance from domestic waste

a technology of organic material and domestic waste, which is applied in the direction of biofuels, solid fuels, shaping presses, etc., can solve the problems of reducing the output of the power plant, not only the non-combustible fractions, but also per se combustible materials such as wood or plastics, to be separated from was

Benefits of technology

[0007] The invention therefore has for its object to improve these known methods such that it is possible to dispense with the separation of plastics and/or wood from the waste before this latter is mixed with flammable material and pressed to form granules. The invention provides for this purpose a method

Problems solved by technology

A problem however is that costly additional measures and provisions are necessary for this purpose, while the thus formed fuel has a lower net heating value than coal, thereby reducing the output of the power plant.
The heretofore known methods, including that of the above stated patent application, have the drawback that not only the non-combustible fractions, but also per se combustible materials such as wood or plastics, have to be separated from the waste before it can be mixed with

Embodiment Construction

[0030] Before the present invention is further described, it is to be understood that this invention is not limited to particular embodiments described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims.

[0031] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range in...

Abstract

A method is provided for converting organic material from domestic refuse into fuel for use in a pulverized coal power plant, comprising of mixing the organic material with at least one flammable material while adding binder, and pressing the mixture to form hard, relatively brittle agglomerates. Further provided is an installation for converting organic material from domestic refuse into fuel, comprising a device for mixing the organic material with at least one flammable material while adding binder, and device for pressing the mixture to form hard, relatively brittle agglomerates.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Pursuant to 35 U.S.C. §119, this application claims priority to the filing date of Dutch Patent Application Serial No. 1027726 filed Dec. 13, 2004; the disclosure of which is herein incorporated by reference. INTRODUCTION [0002] The invention relates to a method for converting organic material into fuel. The invention relates particularly to a method with which the organic material can be converted into a type of fuel which can be ground to powder and is thereby suitable for burning in a pulverized coal power plant. In this application “organic material” is understood to include the combustible fraction of domestic refuse or equivalent industrial waste, so-called RDF (Refuse Derived Fuel). Fibrous material, such as for instance wood chippings, also falls however within this designation. [0003] It is already known per se to convert domestic refuse into a fuel which can be used in electricity power plants. Compared to the combustion of un...
