Procedure

Technical Report

Overview

This Technical Report describes exemplarily methods for the determination of shrinking, deformation, hemisphere and flow temperature for characterising the ash melting behaviour of solid recovered fuels. In order to determine the indicated temperatures, a test piece made from the prepared ash is heated up with constant rate whereas the deformation is continuously observed. The temperatures at which characteristic changes of the shape occur are recorded. The test method described is empirical. The ashes used for the test are homogeneous material, prepared from the fuel, and the determination is performed at a controlled rate of heating in a controlled atmosphere. In contrast, under full-scale conditions, the complex processes of combustion and fusion involve heterogeneous mixtures of particles, variable heating rates and gas compositions. The aim of this Technical Report consists in providing a common and successful practice for describing the ash melting behaviour. CEN/TR 15404 has been prepared by Technical Committee CEN/TC 343 "Solid recovered fuels", the secretariat of which is held by SFS (Finland). The responsible German committee is Working Committee NA 062-05-83 AA "Sekundärbrennstoffe" ("Recovered fuels") of NMP.
