17、4 Introduction Both the limited range and scope of crude oil and other fossil energy sources, as well as the impact on the climate resulting from the anthropogenic output of greenhouse gases, have led to a politically induced initiation of the restructuring of energy usage. In addition to increasing
18、 actual efficiency in the technical utilization of fossil energy sources, the focus is on the development and expansion of renewable energies. The integration of regenerative resources in sustainable heat generation can reduce the output of greenhouse gases such as CO 2 , as well as the need for fos
19、sil energy sources. As a bio-component of blends, fatty acid methyl ester (FAME) is currently used. As a result of the chemical/physical properties, as well as evaporation and combustion characteristics, experience shows that an admixture is possible up to 30 % (V/V) FAME 22, 23. Due to the possible
20、 interactions of the blends with components and in particular with non-ferrous metals such as copper/brass, the manufacturers of consuming units and devices have approved their products only to a limited extent for such an admixture. By contrast, the manufacturers of tanks and components in the fuel
21、 piping consider their products to also be suitable for blends with higher admixtures. However, with regard to the increasing market penetration of blends as a liquid fuel with biogenic or alternative admixtures, requirements for the materials used should be defined and stipulated as standard. There
22、 is, therefore, the need to prove the resistance of the materials used against these fuels. PD CEN/TR 17144:2017CEN/TR 17144:2017 (E) 5 1 Scope This Technical Report includes application-relevant metallic materials of supply systems for liquid fuels and their blends with regard to corrosive or servi
23、ce life reducing influences. Assessment of the specialist literature showed possible interactions with biogenic and alternative fuels and motor fuels as well as their blends with mineral oil and motor fuels. The results of this assessment are given in this CEN/TR. 2 Normative references There are no
24、 normative references in this document. 3 Terms and definitions For the purpose of this document, the following terms and definitions apply. 3.1 material raw, semi-finished or finished substance of given characteristics from which processing into a component or part is undertaken SOURCE: EN 16603-10

29、the existing specialist literature. Note 2 to entry: The term “motor fuel” is valid for the use in vehicles. 3.8 biodiesel liquid motor fuel which consists 100 % (V/V) of liquid biogenic fuels Note 1 to entry: see Clause 5 category B. 4 Materials Table 1 lists material groups and materials, which ar

In the case of the material groups in Table 1 an evaluation of the literature has shown that the resistance against biogenic and alternative fuels and their blends may be limited. The material groups steel, stainless steel and cast iron were not considered
31、here as no limitation of resistance is known for these materials.
