| Abstract [eng] |
Master’s final work analyzes burning of biomass together with fractions of different waste in low-power device. The theme of work is relevant because in individual households the combustion process is the least controlled . There are released dangerous compounds to human health during the combustion process of waste. Biofuel with waste impurities was burned in a laboratory in 13kW solid fuel burning boiler under stable combustion conditions. 13 waste products were chosen for the experiment: newspaper, magazine, bleached paper, package of milk, juice package, cruet of sour cream, tomato sauce bottle, plastic bottle, disposable cups, shampoo bottle, foam sponge, diapers, furniture fabric. During the study the quantity of released polycyclic aromatic hydrocarbons (PAHs) emissions solid particles, were analyzed. The results have shown that the biggest number of solid particles was producedduring the combustion of shampoo bottle and juice package and the lowest amount – for the magazine. The largest quantity of PAHs, which are in the gas phase was produced during the combustion of white paper and the lowest – for the newspaper. Meanwhile, analyzing PAHs in solid phase the largest quantity of it was produced, burning milk package and the lowest – burning magazine. The results showed that gas-phase polycyclic aromatic hydrocarbons are released to the atmosphere during waste combustion. The results of the investigation showed, that the emission of the burning wood pellets is 2 times less than of the magazine, which emitted the least amount of polycyclic aromatic compounds compared to the other examined materials. |
