Opis:
Mercury emission field measurements were conducted for two types of coal from Polish mines. Total mercury content were evaluated in coal and ash on mercury analyzer atomic absorption spectrometer AMA 254. Obtained result shows that brown coal contains more mercury compared to hard coal (289 ppb and 66 ppb respectively for a polydisperse system). Mercury concentration in ashes is several times higher than for coal which means ash may be a good absorber for mercury. Also, application of oxy-fuel technology results in smaller amount of mercury absorbed in the ash which can be related to higher emission of Hg in the gaseous form.

Opis:
Alternative fuels are fuels which include: biomass fuel from waste and sewage sludge. Co-firing biomass with coal is now considered as an effective and financially attractive way the use of biomass for energy production. Perhaps in the future this new technology will replace co-efficient technologies, such as gasification in combination of the gas-steam systems, and the use of gas or ethanol from biomass to value highly efficient fuel cells [1]. The use of coal and biomass mixtures can also be a threat to the safe operation of the plant, including in particular the preparation and installation of the fuel supply. Organic matter in biomass (organic fraction) is a complex mixture of fats, proteins, carbohydrates, humic material-go and fatty acids [2–4]. Self-igniting the fuel can be the result of various factors such as chemical, physical or biological agents stored inside a large amount of organic matter. Self-igniting solid fuels storage depends on many factors such as particle size, nature and type of biomass, coal, the moisture content of the fuel, the storage method and the means of ventilation [5]. In order to determine the self-ignition temperature of coal and of biomass: straw pellets and wood pellets, the method called CPT (Crossing Point Test) [18] was used. Apart from this, the elemental composition of these biomass as well as of coal have been marked.

Opis:
The paper presents the results of the mechanical, electrical, CCSEM and XRD measurements of hard coal, conducted in simulated conditions of sintering in atmospheres of O2/CO2,. The changes of the coal ash resistivity are correlated with the content of the oxides and with the sintering temperature determined by the mechanical test and Leitz method. The SEM-EDS analysis was conducted for deposits on the probe. The changes of the measured ash samples, observed during sintering process in O2/CO2 atmosphere, were discussed in the ash microstructure point of view.
