Possible utilization of SRF (solid recovered fuel) in the energy industry is a widely investigated topic, because even though it economically feasible, its complex reactions make steady operation hard to maintain. prepared as mixture well-combustible (but not recyclable) parts municipal and industrial waste, which consists mainly various papers, plastics textiles with very different combustion characteristics. To describe kinetics sample like this, more advanced methods recommended. In this work, genetic algorithm was used fit four reaction models thermogravimetric data measured oxidative atmosphere, results were compared. It concluded that tested distributed activation model simple expanded nth-order offer only slightly better fitting value for special sample, promotes usage simpler first-order model.
