Solid recovered fuels - Determination of moisture content using the oven dry method - Part 1: Determination of total moisture by a reference method

This Technical Specification specifies a method for the determination of total moisture content of solid recovered fuels by drying a sample in an oven. This method is suitable for use if a high precision of the determination of moisture content is required. It is applicable to all solid recovered fuels.
NOTE 1   The total moisture content of solid recovered fuels is not an absolute value and therefore standardised conditions for its determination are indispensable to enable comparative determinations.
NOTE 2   The term moisture content when used with recovered materials can be misleading since solid recovered materials, e.g. biomass, frequently contains varying amounts of volatile compounds (extractives) which can evaporate when determining moisture content by oven drying.
NOTE 3   This Technical Specification is based on EN 14774 1 [1].

Feste Sekundärbrennstoffe - Bestimmung des Wassergehaltes unter Verwendung des Verfahrens der Ofentrocknung - Teil 1: Bestimmung des Gesamtgehaltes an Wasser mittels Referenzverfahren

Diese Technische Spezifikation legt ein Verfahren zur Bestimmung des Gesamtgehaltes an Wasser von festen Sekundärbrennstoffen durch Trocknen einer Probe in einem Ofen fest. Das Verfahren ist geeignet, wenn eine hohe Präzision der Bestimmung des Wassergehaltes erforderlich ist. Es gilt für sämtliche festen Sekundärbrennstoffe.
ANMERKUNG 1   Der Gesamtgehalt an Wasser von festen Sekundärbrennstoffen ist kein absoluter Wert, und deshalb sind genormte Bedingungen für seine Bestimmung unerlässlich, um vergleichbare Bestimmungen zu ermöglichen.
ANMERKUNG 2   Der Begriff Wassergehalt kann bei der Anwendung im Zusammenhang mit festen Sekundär¬brenn-stoffen irreführend sein, weil feste Sekundärbrennstoffe, z. B. Biomasse, oft unterschiedliche Mengen an flüchtigen Verbindungen (Extraktstoffen) enthalten, die bei der Bestimmung des Wassergehaltes durch Ofentrocknung verdampfen können.
ANMERKUNG 3   Diese Technische Spezifikation beruht auf EN 14774-1 [1].

Overview

SIST-TS CEN/TS 15414-1:2010 defines a reference oven-dry method for determining the total moisture content of solid recovered fuels (SRF). The method is intended where high precision and comparability of moisture determinations are required and is applicable to all types of solid recovered fuels. It is based on earlier work in EN/ prEN 14774-1 and references SRF sampling and preparation standards.

Key Topics

• Principle: Dry a representative laboratory sample in an air‑circulating oven at (105 ± 2) °C until constant mass is reached, then calculate moisture from the mass loss.
• Apparatus requirements: A temperature‑controlled drying oven (105 ± 2 °C) with 3–5 air changes per hour, non‑corrodible dishes or trays with clean even surfaces, and a balance accurate to 0.1 g.
• Sample size & preparation: Minimum sample mass is 300 g (preferably > 500 g); for large particle sizes (nominal top size 100 mm) 1–2 kg is recommended. Prepare samples following prEN 15442 and prEN 15443 to maintain representativity.
• Drying procedure: Spread the sample thinly on the dish (approx. 1 g per 100 mm2 surface area; 0.5 g per 100 mm2 for very low bulk density). Use a reference dish for buoyancy correction and reweigh dishes while still hot within 10–15 s to avoid re‑adsorption.
• Mass constancy: Dry until further heating at (105 ± 2) °C for 60 minutes causes a change of no more than 0.2 % of the total loss in mass. Generally avoid drying longer than 24 hours to limit loss of volatile extractives.
• Safety note: Some SRF components may present a risk of self‑ignition when heated; follow laboratory safety procedures.

Applications

This Technical Specification provides a standardized, high‑precision procedure for:

• Quality control and fuel specification of SRF for energy recovery and co‑firing applications
• Comparative laboratory testing between suppliers, users and certification bodies
• Supporting accurate conversion between wet basis and dry basis moisture values for calorific and process calculations

Practical advantages include reproducible moisture data for contract testing and improved confidence when reporting fuel characteristics.

• prEN 15443 - Solid recovered fuels: laboratory sample preparation
• prEN/EN 14774-1 - Solid biofuels: oven dry method (basis for this TS)

Test reports shall record laboratory identity, test date, sample identification, reference to CEN/TS 15414-1, any deviations, results (wet or dry basis) and unusual observations. Note that due to SRF heterogeneity, no precision (repeatability/reproducibility) is given in this Technical Specification.
