Quality assurance of solid recovered fuels (SRF)

The utilization of solid recovered fuels for energy recovery has established itself and has been increasing steadily in recent years in Europe. A permanent availability in the area of solid recovered fuels can only be achieved with a fuel of constant quality that is appropriately matched with the combustion technology. In this case, it is necessary to define quality standards and introduce targeted quality assurance measures.

1 Introduction

The terminology for treated wastes used either in mono-incineration or co-incineration application varies. In Germany, waste for energy recovery is generally subdivided into solid recovered fuels and high-calorific fractions. A solid recovered fuel is a specially prepared fuel made of production-specific or municipal waste that has been treated adequately for co-incineration. Solid recovered fuels that comply with a defined quality standard according to RAL-GZ 724 [RAL, 2012a] are known by the protected brand name SBS®. By contrast, high calorific fractions have undergone a...
