This document specifies a method for the determination of the characteristic temperatures for the ash melting behaviour of solid biofuels.
Abstract
Overview
ISO 21404:2020 - "Solid biofuels - Determination of ash melting behaviour" specifies an empirical laboratory method to determine characteristic temperatures that describe the ash melting (fusibility/softening) behaviour of solid biofuels. The method uses ash prepared under controlled ashing conditions, a standardized test piece, controlled heating and atmosphere, and continuous observation to record temperatures at which defined shape changes occur. Results are used to compare tendencies of different biofuel ashes to form deposits or cause bed agglomeration in combustion systems.
