Abstract
Exploring alternative options to address the impending global energy crisis while taking environmental concerns and climate change mitigation into account and addressing the skyrocketing energy demand has become urgently essential. This need is further highlighted by the Republic of Serbia's significant reliance on imported energy sources and its energy sector's strategy focus, which implies the rational use of energy resources, use of RES, and waste management with satisfying environmental regulations. The use of low-calorific and waste materials in conjunction with fluidized bed combustion (FBC) technology is the method to achieve all of the above goals synergistically. This paper presents experimental results of the combustion of several solid wastes (Kolubara's coal mining waste, paper sludge and hazelnut shells), conducted in an industrial demonstration and experimental bubbling FB boiler (capacity up to 500 kW). Burning these wastes has a variety of advantages, including recovering substantial energy remaining in them and minimizing overall waste volumes. The furnace temperature distribution, the flue gas composition at the furnace exit, and other combustion parameters of the tested fuels are given. Based on these results, an evaluation of FB combustion of waste fuels and the possibility of utilization of their energy potential is given.
