This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2011, and confli
14、cting national standards shall be withdrawn at the latest by September 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This docu
15、ment supersedes CEN/TS 15234:2006. The European standard series EN 15234 Solid biofuels Fuel quality assurance are provided as a general requirements and additional standards. Additional standards may extend this series over time. EN 15234 consists of the following parts, under the general title Sol
16、id biofuels Fuel quality assurance: Part 1: General requirements; Part 2: Wood pellets for non-industrial use (under development); Part 3: Wood briquettes for non-industrial use (under development); Part 4: Wood chips for non-industrial use (under development); Part 5: Firewood for non-industrial us
17、e (under development); Part 6: Non-woody pellets for non-industrial use (under development). Although these standards may be obtained separately, it should be recognised that they require an understanding of the standards based on and supporting EN 15234-1. It is recommended to obtain and use EN 152
18、34-1 in conjunction with these standards. NOTE In these standards, non-industrial use means: use in smaller scale appliances, such as, in households, in small commercial and public sector buildings. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follow
19、ing countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovak

BS EN 15234-1:2011EN 15234-1:2011 (E) 4 Introduction The overall aim of this European Standard is to guarantee the solid biofuel quality through the whole supply chain, from the origin to the delivery of the solid biofuel and to provid
21、e adequate confidence that specified quality requirements are fulfilled. The solid biofuel supply chain usually consists of the main stages described in Figure 1. Figure 1Solid biofuel supply chain The objective of this European Standard is to serve as a tool to enable the efficient trading of biofu
22、els. Thereby: a) end-user can find a biofuel that corresponds to its needs; b) producer/supplier can produce a biofuel with defined and consistent properties and describe the biofuel to the customers. Quality assurance measures shall establish confidence in the biofuel through systems that are simpl
23、e to operate and do not cause undue bureaucracy. Solid biofuels are specified according to EN 14961 series Solid biofuels Fuel specifications and classes. According to the terminology of EN ISO 9001:2008 1, a Quality Management system generally consists of quality planning, quality control, quality
24、assurance and quality improvement. This European Standard covers fuel quality assurance (part of quality management, focused on providing confidence that the quality requirements will be fulfilled) and quality control (part of quality management, focused on fulfilling the quality requirements). The
25、users of this European Standard may integrate EN 15234-1 in their general quality assurance scheme, e.g. the EN ISO 9000 series 1, 2, 3. If the company does not have a quality management system, this European Standard can be used on its own to help the supplier in documenting fuel quality and creati
26、ng adequate confidence between the supplier and the end-user. NOTE This European Standard for fuel quality assurance is only concerned with the fuel part. To ensure the efficient use of solid biofuels, the relationship between the fuel and the combustion unit is also important to consider. It is rec
27、ommended that the end-users ensure that the combustion technology used and the solid biofuels are compatible to achieve an optimised burning process. In addition to high efficiency, the environmental impact is reduced when the combustion process is optimised (e.g. unburnt carbon in the ash will be r
28、educed; the emissions from the flue gases are reduced, etc.).

30、). This European Standard covers the whole chain, from supply of raw materials to point of delivery to the end-user. According to the mandate given for the standardisation work, the scope of the CEN/TC 335 only includes solid biofuels originating from the following sources: products from agriculture
31、 and forestry; vegetable waste from agriculture and forestry; vegetable waste from the food processing industry; wood waste, with the exception of wood waste which may contain halogenated organic compounds or heavy metal as a result of treatment with wood preservatives or coating, and which includes
32、 in particular such wood waste originated from construction and demolition waste; fibrous vegetable waste from virgin pulp production and from the production of paper from pulp, if it is co-incinerated at the place of production and heat generated is recovered; cork waste. NOTE 1 The quality assuran
33、ce systems applied to the operation of conversion plants fuelled by solid biofuels are outside the scope of this European Standard. NOTE 2 Health, safety and environmental issues for solid biofuels are important and need special attention, however they are outside the scope of this European Standard
34、. NOTE 3 For the avoidance of doubt, demolition wood is not included in the scope of this European Standard. Demolition wood is defined as “used wood arising from demolition of buildings or civil engineering installations” (EN 14588:2010, 4.52). NOTE 4 The biofuels covered by this European standard
35、are identical to the fuels exempted from the Directive 2000/76/EC Article 2.2 a) from i) to v) on incineration of waste. NOTE 5 Aquatic biomass is not included in the scope of this European Standard. 2 Normative references The following referenced documents are indispensable for the application of t

44、he supply chain and the information to be used in the quality control of the biofuel. This ensures traceability and gives confidence by demonstrating that all processes along the supply chain (of solid biofuels) up to the point of the delivery to the end-user are under control. Figure 2 illustrates
45、the principle of this standard and the procedures to establish confidence in the biofuel. Traceability Production requirements Product declaration Person/ Organisation responsible: 1stoperator providing the resource as a feedstock for energy purposes Producer of the solid biofuel who is responsible
46、for the maintenance of the fuel quality until it is delivered to the end-user or retailer. If the producer is a direct supplier for end-user it is him/her who has to provide a product declaration. Supplier/retailer of solid biofuels to the end-user Actions: Providing accurate information on the orig
47、in, source and location the feedstock was taken from. Processing, handling and storage of the solid biofuels ensuring the solid biofuel is supplied in the quality that has been declared. Ensuring the customer receives products as declared in the product declaration and the declaration is accurate an
48、d appropriate for the end-users requirements Example of demonstrating compliance This can be achieved through a combination of using EN 14961-1:2010, Table 1 Origin and Source and having a declaration where possible on the location of the feedstock This can be achieved by providing a declaration abo
49、ut origin, source an location according to EN 14961-1:2010, Table 1 at the location of the feedstock wherever possible Product declaration, backed up with quality control verification and quality assurance documentation and test data (as appropriate) Figure 2 Illustration of principle.
