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

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.

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, NOx, HCl, SO2

• 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.

Overwiev of existing voluntary labels for pellet appliances

• P-marking of pellet burners, pellet boilers and pellet stoves (Sweden) emissions, safety, function, surveillance inspections

• Nordic Ecolabelling of Solid biofuel boilers (Scandinavia) emissions, efficiency, environmentally responsible product design

• Der Blaue Engel (Germany) emissions, efficiency, safety, auxiliary power demand, environmentally responsible product design

• Din Plus for pellet stoves (Germany) emissions, efficiency

• Umweltzeichen 37 (Austria) emissions, efficiency, auxiliary power demand,
