Småskalig förbränning av returträflis: En studie om möjligheterna för mindre fjärrvärmeverk i norra Sverige att förbränna returträflis (RT-flis)

The purpose with this report was to investigate the possibilities for smaller district heating plants to use recovered wood waste (RT-flis) as fuel. A smaller district heating plant in the north of Sweden (Sorsele värmeverk AB) was the main study object. To be able to incinerate this fuel there are a number of requirements that need to be fulfilled according to the law. In addition to these requirements, the incineration of this fuel also needs to be profitable. The results for this study were obtained through interviews, investigations of the incineration laws and the fuel supply, as well as an analysis of the opinions occurring within the personnel of the heating plants. The results show that the possibility to incinerate RT-flis depends on the appropriate technology; the possibility to fulfill the requirements of the law, as well as it has to be profitable. All these parameters are in close relation to each other. Whether it is technologically possible to use RT-flis largely depends on the construction and technology of the heater, which affects the possibility to fulfill the requirements on, for example, air emissions. Economically, main issues include investments into measuring equipment, but also the accessibility of fuel. The most important aspect is the quality of the fuel (e.g., contaminations).
