Описание (английский):

ISO 19743:2017 specifies a method for the determination of content of heavy extraneous materials larger than 3,15 mm by the use of sink-and-float separation combined with elutriation. This document is applicable to woody biomass in accordance with ISO 17225‑1:2014, Table 1.

Abstract

Overview

Key Topics

Heavy Extraneous Materials Identification The standard focuses on identifying inorganic, high-density materials with a specific density greater than 1 g/cm³ and particle sizes above 3.15 mm. These impurities are differentiated from lighter, low-density materials (e.g., plastic foils) that can also be manually sorted during testing.
Sink-and-Float Separation Principle Separation is achieved by immersing the biomass sample in water to allow heavy materials to sink, followed by elutriation-a process where upward water flow helps separate particles based on size, shape, and density.
Sample Preparation and Processing Minimum sample volume of 20 liters is required, prepared according to ISO 18135 and ISO 14780. The sample is divided and analyzed, incorporating moisture content determination consistent with ISO 18134-1 or ISO 18134-2.
Drying and Weighing After separation and sieving using a 3.15 mm mesh, the retained sediment is dried at controlled temperatures to reach constant mass before weighing. This step ensures precise measurement by removing moisture influences.
Calculation Methodology The content of heavy extraneous materials is calculated as a percentage of dry biomass mass using a standardized formula involving weights before and after drying and moisture content data.
Reporting Requirements Clear test reporting is mandated, including test identification, product details, test results, any deviations or unusual observations, and reference to ISO 19743:2017.

Applications

Biofuel Quality Control Ensuring solid biofuels comply with quality specifications by quantifying inorganic contamination levels helps prevent operational issues such as equipment wear, corrosion, and emissions problems.
Combustion Process Optimization Accurate assessment of heavy extraneous materials supports the optimization of combustion processes, reducing ash formation and improving energy recovery efficiency.
Supply Chain Verification Biomass suppliers and end-users can use this standard method to verify the purity of feedstock, enhancing transparency and trust in biomass fuel transactions.
Environmental and Safety Compliance Identifying impurities such as glass or metal helps mitigate environmental hazards and safety risks associated with biomass handling and combustion.
