What is BS EN 15415-3 – Image analysis method for solid recovered fuel particles about?
BS EN 15415-3 specifies the determination of particle size distribution of solid recovered fuels using an image analysis method.
BS EN 15415-3 applies to both agglomerated and non-agglomerated solid, recovered, fuel pieces exhibiting an irregular shape, such as shredded end-of-life tyres and demolition woods.
BS EN 15415-3 provides the determination of the maximum projected length as well as parameters such as equivalent diameter. It also gives a characterisation of the filaments protruding from the SRF pieces.
Who is BS EN 15415-3 - Image analysis method for solid recovered fuel particles for?
BS EN 15415-3 on image analysis method for solid recovered fuel particles is useful for:
- Solid recovered fuel industry
- Producers and suppliers of SRF
- Testing laboratories
- Quality control bodies
- Persons involved in the entire delivery chain
Why should you use BS EN 15415-3 - Image analysis method for solid recovered fuel particles?
Partical size distribution is essential for understanding the physical and chemical properties of a material for user, manufacturers of solid recovered fuels.
BS EN 15415-3 is dedicated to outlining an optical method for characterizing the size of pieces of solid recovered fuel (SRF) that exhibit an irregular shape and are generally large in size. Typical examples are shredded end-of-life tyres or demolition woods.
When such products reach the end-of-life stage, they continue to exhibit the very strong mechanical properties for which they were designed and fabricated. For instance, tyres are designed and fabricated to withstand cutting. Therefore, it is wise to minimise shredding when producing SRF from these end-of-life products.
This results in a general in production of SRF pieces exhibiting an irregular shape and large size.
These SRF cannot be characterised using the sieving method specified in EN 15415-1 which utilises well-known distribution curves and a series of test sieves.
Consequently, the method specified in BS EN 15415-3 is an optical method based on the determination of the maximum projected length and accompanied by an appropriate statistical evaluation. This maximum projected length approach is needed for sake of testing; but it is mainly needed to facilitate the use of these solid recovered fuels.
Safe transportation (e.g. with conveyer) and introduction into the combustion zone are dependent on the design and operations adapted to such maximum length.
In BS EN 15415-3, the maximum projected length determination is complemented with a characterisation of the filaments protruding from the SRF pieces (see 3.1).
Note: BS EN 15415-3 is based on CEN/TS 14243, AFNOR XP T47-753, AFNOR XP T47-756, AFNOR XP T47-757, AFNOR NF X11-696:1989 and ISO 13320.
