POSSIBILITIES OF ENERGY USE OF WASTE FUELS IN HEAT SOURCES IN HOUSEHOLDS
Abstract
Various users of small heat sources in household use incorrect solid fuels. This leads to a higher burden on the environment, mainly due to higher production of emissions, but also to various problems during the operation of the heat source. These various complications may arise as a result that these fuels usually have low bulk density, high ash content, low ash melting temperatures, and low calorific values, which lead to combustion problems and often also the emission formation and further environmental burden. This article deals with the emission formation during the combustion of four types of alternative fuels: leaves, lawn clipping and two types of solid non-separable waste. One type contained more plastic (plastic solid non-separable waste). Ash melting temperatures were also observed due to possible deposit formation, slagging, and sintering which can also lead to accidental damage to the heat source the inability to heat the household. The results confirmed that the combustion of fuels not recommended by the manufacturer of the heat source significantly increases the emission formation and causes combustion problems. When using tested fuels, there was detected a higher ash content, a higher concentration of particulate matter, and higher production of carbon monoxide, nitrogen oxides, and sulfur oxides.
