Obecnie ze względu na narastające potrzeby energetyczne świata oraz świadomość zagrożeń związanych z emisją gazów cieplarnianych, wykorzystanie energii z odpadów staje się coraz bardziej pożądane. Fluidalna technologia spalania to czysta i wydajna technologia ze względu na doskonałe właściwości mieszania i wymiany ciepła. Pozwala ona na wykorzystanie paliw nie tylko takich jak węgiel, czy biomasa, ale również komunalne odpady stałe. Coraz powszechniejszą tendencją jest częściowe lub całkowite zastąpienie paliw kopalnych przez paliwa alternatywne m.in. biomasę i RDF/SRF. Wartość opałowa tych paliw jest wysoka, zbliżona do węgla brunatnego. Największym wyzwaniem w stosowaniu paliw alternatywnych jest ogromne zróżnicowanie właściwości chemicznych i fizycznych tych paliw. W pracy przedstawiono analizę procesu spalania wytworzonych z odpadów komunalnych peletów RDF w zmiennej temperaturze prowadzonego procesu spalania. Badania przeprowadzono na reaktorze laboratoryjnym z cyrkulacyjnym złożem fluidalnym. Badania Zostały przeprowadzone w trzech różnych temperaturach komory spalania: 850°C, 750°C i 650°C i w strumieniu materiału inertnego Gs=2,5kg/m2s i Gs=5kg/m2s modelującym warunki w rzeczywistym palenisku. Z badań wynika, że technologia fluidalna może być uważana za jedną z bardziej efektywnych metod unieszkodliwiania odpadów komunalnych przy jednoczesnym wykorzystaniu ich potencjału energetycznego. Mogą one być z powodzeniem wykorzystywane zarówno w procesie spalania oraz zgazowania, czy pirolizy.

Nowadays, due to the growing energy needs of the world and awareness of the threats associated with greenhouse gas emissions, the use of energy from waste is becoming more and more desirable. Fluidized bed combustion technology is a clean and efficient technology in view of its excellent mixing and heat transfer characteristics. It allows the use of fuels not only such as coal or biomass, but also municipal solid waste. The current trend is to partially or fully replace fossil fuels by alternative fuels such as biomass and Refuse Derived Fuel (RDF )/ Solid Recovered Fuels (SRF). The calorific value of these fuels is high, while also competitive in comparison with lignite. The biggest challenge in the use of alternative is that these fuels have different physical and chemical properties. The paper presents an analysis of the combustion process of RDF pellets produced from municipal waste at a variable temperature of the combustion process. Tests were carried out in a laboratory reactor with a circulating fluidized bed. The research was carried out at three different temperatures of the combustion chamber: 850°C, 750°C and 650°C and in the stream of material Gs=2.5kg/mzs and Gs=5kg/mzs modeling the conditions in a real boiler. The study shows that fluidized bed combustion can be considered to be one of the most efficient methods of neutralizing municipal waste while using its energy potential. They can be successfully used both in the process of combustion and gasification or pyrolysis
