Labelling draft for Pellets EN agro Proposal from MixBioPells to European Pellet Council: Handbook for the certification of non-woody pellets based on EN 14961-6
EN 14961-6 Straw EN 14961-6 Miscanthus EN 14961-6 Reed grass canary EN 14961-6 EN 14961-6 B
The certificattion system contains the following essential points Requirements for pellet production and quality assurance (EN 15234-6) Requirements for the product (EN 14961-6) Requirements for labelling, logistics and intermediate storage Requirements for the delivery to end customers MixBioPells - IEE/09/758
Labelling draft for Pellets The essential components of the labelling draft are: Inspection and verification of the compliance of the agro and mixed biopellets with the European standards, as well as the logistics system (up to the end customer s store), both according to the requirements written in this manual Specifications for the in-house quality management (certificate holder facilities and processes, employee qualifications, documentation duties, internal quality control) The execution of certification and external controls, license issuing and revoking, handling of complaints.
Product Quality The quality of the pellets corresponds to the classes of the EN 14961-6. ENagro-cereal straw pellets ENagro-miscanthus pellets ENagro-reed canary grass pellets ENagro-blended pellets class A 5 ENagro-blended pellet class B MixBioPells - IEE/09/758

Labelling draft for combustion appliances
Compared to the combustion of woody biomass, the main fields of problems for the combustion of alternative and mixed biomass fuels are: Slagging tendencies in the bottom ash Increased emissions on dust, NO x, HCl, SO 2 Increased risks of corrosion and fouling
The following combustion related parameters were identified by the project consortium to be considered in a labeling system for mixed pellets: Low emissions (CO, NOx, Particles) Small particles (PM 10 or PM 2.5 µm) Efficiency Measuring methods Ash amount and behavior Ash melting behavior Long term performance
Overview of existing standards for testing pellet appliances EN 303-5 Heating boilers: Heating boilers for solid fuels, hand and automatically stoked, nominal heat output of up to 300 kw Testing fuels: wood logs, wood briquettes, wood pellets, a number of fossil fuels EN 14785:2006 Residential space heating appliances (< 50 kw) Testing fuels: wood pellets EN 15270:2007 Pellet burners for small heating boilers (< 70 kw) Testing fuel: high quality pellets. Other fuels will be considered in future amendments
Requirements in EN 303-5:1999 - Production documentation - Drawings including material used and welding process - Quality manual - Safety and design requirements - Material used (steel/cast iron), wall thickness, water side connections, water side resistance, temperature control and limiting devices for open and closed vented system, cleaning of heating surfaces, insulation, electrical safety (according to EN 60335-1), etc. - Boiler performance requirements - Boiler efficiency - Emission (CO, OGC and dust; NOx is optional) - Heat output and combustion period (2h, 4h, 6h)
Test fuels in EN 303-5:1999
Revision of EN 303-5:1999 - Boilers up to 500 kw - Non woody biomass such as straw, miscanthus, reeds, kernels and grains. (Suggestion: According to the range specification of the manufacturer or EN 14961) - Additional safety requirements for automatically stoked boilers. - Risk analyses shall be done by the manufacturer. - Higher emission- and efficiency requirements.
