The paper presents an overview of non-destructive quality control methods and some examples of test results of elements of prototype module of drying line used to receive RDF fuel from waste recycling. The line is object of considerable size and the authors used to control parts non-destructive methods with should be fully mobile and autonomous. During test the researchers used such methods as ultrasonic and penetration methods. In the article was shown not only the physical basics of used methods, the advantages and limitations of each method, but also test results. The publication contains examples of pulses obtained on the screen of ultrasonic flaw detector along with their interpretation. The results of investigations by liquid penetrant method were presented. The last part of publication is summary, which classified the scope of use of each method presented in the article.
