RDF Characterization for More Efficient Use in Combustion Systems ^†

1. Introduction

The main systems for solid municipal waste (SMW) management involve the separation of all recyclable materials and the last fraction, usually named refuse-derived fuel (RDF), which contains all non-recyclable materials with different particle sizes and variable moisture, depending on the efficiency of the management system [1,2,3]. Usually, due to its convenient calorific value, the dried RFD is used in the cement industry for the partial replacement of solid fuels [1].

To answer specific issues in the Integrated Management Center from Tarpiu, Bistrita Nasaud County, through the CleanTech Project, funded under the frame of POC 2014–2020 Structural Funds Programme, a complete characterization of produced RDF is under evaluation.

2. Materials and Methods

In this study, the RDF recovered from SMW separation was decomposed in a fixed-bed reactor and the condensable fraction was analyzed be gas chromatography coupled with mass spectrometry (GC/MS) using a Perkin Elmer analyzer.

3. Results

The main compounds in the liquid phase collected during the thermochemical decomposition in an oxygen-free atmosphere of tested RDF were identified. In Figure 1, the chemical structure of these compounds and their retention time are presented.

4. Conclusions

By applying GC/MS analyses, the main compound released by the RDF in thermochemical applications can be identified, which allows a better control of post-treatment procedures efficiency.
