Исследование параметров горения жидкого углеводородного топлива при его распылении перегретым водяным паром, углекислым газом и их смесью

Abstract

Reducing the anthropogenic impact on the environment is one of the priority tasks of our time. One of the sources of pollution is the burial of a large amount of substandard combustible waste, including hydrocarbon waste, which is not currently in demand, as well as solid and toxic substances generated during combustion. The solution to the identified problems is possible through the Waste-to-Energy approach, aimed at involving combustible waste in the fuel balance, with the organization of low-temperature combustion by adding various diluent gases - carbon dioxide or water vapor. In this work, using diesel fuel as an example, the combustion characteristics of liquid hydrocarbons in the presence of a mixture of superheated steam and carbon dioxide in a spray burner were experimentally obtained and compared to identify the features and advantages of their use in Waste-to-Energy approaches. It is shown that for all studied modes a high completeness of fuel combustion is observed. Analysis of the composition of combustion pro¬ducts shows that when replacing superheated steam with carbon dioxide, the content of CO and NOx in combustion products increases by 25%. At the same time, all studied modes comply with the EN:267 standard. The results show that it is possible to implement approaches of adding carbon dioxide, water vapor and a mixture of both to convert waste into energy.
