Solid biofuels - Determination of particle density; German version EN 15150:2011
Feste Biobrennstoffe - Bestimmung der Partikeldichte; Deutsche Fassung EN 15150:2011
Overview
This document describes a method for determining the particle density of compressed fuels such as pellets or briquettes. Particle density is not an absolute value and conditions for its determination have to be standardised to enable comparative determinations to be made. Both mass and volume of an individual particle or a group of particles are determined. The volume is measured by determining the buoyancy in a liquid. This procedure follows the physical principle that the buoyancy of a body is equal to the weight of the displaced volume of a liquid. The apparent loss in weight between a measurement in air and the subsequent measurement in liquid marks its buoyancy. The volume of the sample body is calculated via the density of the applied liquid.
