Inspection Methods For Wood Pellets, Solid Fuels, And Wood Pellet Biomass Fuels
Apr 07, 2018

1.  EU standardization of wood pellet biomass fuel EU standardization of  wood pellet biomass fuel started in 2000. There are currently 30  technical specifications, divided into terms, specifications,  classification and quality assurance, sampling and sample preparation,  and physics (or mechanical) Characteristics, chemical properties and other five aspects.

2.  Standard Test Method for Wood pellet Biomass Fuel in the United  States Standards for solid fuel-related test methods developed by the  ASTM Institute of the United States, mainly including the biomass bulk  density, ash content, volatile matter, element analysis, wood fuel  analysis, spherical particle combustion chamber 9  standards such as heating furnace, wood pellet fuel moisture content  test for microwave oven, charcoal chemical analysis test method,  charcoal particle size distribution, abrasion resistance, etc.; American  Agriculture and Biological Engineering Association has formulated  biomass product harvesting, collection, storage and transportation ,  processing, conversion, application terms and definition standards;  product standards developed by the Institute of Biomass Particle Fuels,  the main product indicators include shape, bulk density, mechanical  strength, ash and chloride; the United States Department of Defense has  formulated for the preparation of ammunition Charcoal standard. ASTM biomass fuel standard.



3,  other European national standards Swedish solid molding fuel standard  SS 187120, mainly including dimensions, density, durability, moisture,  ash, total moisture (transport), calorific value, sulfur, chlorine and  other indicators. Prior  to the promulgation and implementation of the EU standard, it was  widely adopted by European countries such as Finland and Denmark. German  wood molding fuel standard DIN 51713, the performance indicators for  arsenic, calcium, chromium, copper, mercury, lead, zinc, organic halogen  extraction and other elements have made more detailed requirements. Charcoal  standard DIN 51749, mainly includes moisture content, ash, fixed  carbon, particle size, adhesives and other indicators. Austria  is divided into raw materials and bark according to different sources  of raw materials. Onorm M7135 and Swedish standards contain roughly the  same product standards. Onorm M7136 and Onorm M7137 are also  supplemented with quality and specifications. In  addition, Switzerland also has a corresponding SN 166000 standard; the  United Kingdom is divided into three levels (1010, 3% or 6%) based on  the ash index, which is basically the same as the Swedish standard;  Finland, Denmark and other countries mostly adopt Swedish standards.
