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.
