    Opis:
    The paper presents the results of a research on the effects of process parameters on the combustion of waste plastics. The experiments were carried out in a laboratory fluidized bed reactor. The temperature and the conditions of the process were changed during the experiments. The plastics were combusted continuously (autothermally), periodically with extra fuel (co-firing) and alone in a hot fluidized bed. During the combustion process of materials containing nitrogen (PA, ABS), while the bed temperature decrease, changes of emissions of nitrogen oxides, in particular an increase in the concentration of N2O, up to 250 ppm at ~730°C, were observed. During ABS combustion, emission of HCN was registered, at a maximum of 400 ppm. The presence of the supporting fuel (LPG) resulted in the stabilization and acceleration of the plastic samples degradation process. The rate of thermal decomposition of waste materials depended on its elemental composition and also the physicochemical properties.

    Opis:
    This study presents the use of fluidised bed combustion to produce thermal energy, aluminium recovery and the reduction of the Tetra Pak and Combibloc packaging waste stream. Fluidisation and the pneumatic transport, which take place in the same apparatus, allow recovering bits of the aluminium foil from the combustion zone. The limited time spent in the high temperature zone leads to a high content of free metal in the solids separated in the ash trap and cyclone. Other solid products are practically chemically inert and may be disposed in a landfill of municipal or inert wastes.

    Opis:
    The purpose of this article is to present the possibilities of coal shale combustion in furnaces with bubbling fluidized bed. Coal shale can be autothermally combusted in the fluidized bed, despite the low calorie value and high ash content of fuel. Established concentrations of CO (500 ppm) and VOC (30 mg/m3) have indicated a high conversion degree of combustible material during combustion process. Average concentrations of SO2 and NOx in the flue gas were higher than this received from the combustion of high quality hard coal, 600 ppm and 500 ppm, respectively. Optional reduction of SO2 and NOx emission may require the installation of flue gas desulphurization and de-NOx systems.

    Opis:
    The paper discusses the possibility of using the reversible reaction CaCO3 ↔ CaO + CO2 for the cyclic capture and release of CO2 directly inside a fluidised bed combustor. This could lead to the lowering of CO2 emissions into the atmosphere, as part of an effort to mitigate the greenhouse effect associated with the rising atmospheric CO2 concentrations resulting from obtaining energy from burning fossil fuels. An enrichment coefficient E has been introduced and defined as a measure of the production of CO2 (on calcining CaCO3) or its removal (on carbonation of CaO) with respect to the level associated with fuel combustion alone. The observations made on the effect of introducing an additional external stream of CO2 on the efficiency of the chemical capture process have been described. Through an appropriate control of the temperature inside the reactor it is possible to change the value of E over the range [-0.8; 0.8]. This implies that up to about 80% of the CO2 derived from the fuel can be temporarily retained within the bed and released later, at a higher concentration. The proposed method of burning fuel in a chemically active fluidised bed could be an available method leading to CO2 isolation from the flue gases and leading to its eventual sequestration.
