Abstract

The invention relates to a method for determining the contents of volatile component industrial components of refuse-derived fuel (RDF) and calculating a heat value of the RDF. The method is characterized in that characteristic temperatures T1, T2 and T3 appearing when the various volatile industrial components are released, the contents V1, V2 and V3 of the volatile component industrial components 1, 2, and 3, and the moisture content Mad, ash content Aad and constant carbon content FCad in the RDF are determined by virtue of thermogravimetric analysis, and then the heat value Q of a to-be-tested refuse-derived fuel sample can be calculated according to an empirical formula Q=-32100Mad+7850V1+19930V2+20750V3+23660FCad+4110.45. An experiment can be completed and needed data can be acquired by utilizing a conventional drying box, a muffle furnace and an analytical balance, so that the heat value of the RDF can be finally calculated. The method is suitable for being used in factories with simple test means.

Description

Technical field [0001] The invention relates to a method for determining the content of volatile industrial components of refuse derived fuel (RDF) and calculating the calorific value. Background technique [0002] In recent years, the disposal of municipal solid waste has become increasingly serious. The current methods for treating municipal solid waste mainly include incineration, composting, and landfilling. Among them, the incineration energy generation method has developed rapidly in my country. However, the direct incineration of municipal solid waste for energy production requires higher equipment and lower utilization rate. Therefore, refuse-derived fuel technology is produced. Refuse-derived fuel (RDF) is a kind of high calorific value produced by sorting, crushing, eddy current removal of aluminum, magnetic separation and removing iron, and then further crushing, sorting, extrusion molding and drying. Solid fuel with good combustion stability. [0003] The calorific ...
