“…While using the original atmospheric spray-type burner for burning heptane [50], diesel fuel [48], waste oil [47], fuel oil [51], and crude oil [52], it was shown that this method allows a reduction in soot, CO, and NO x formation. For burners with a forced air supply to the combustion chamber [53], regimes providing significant reduction in the content of nitrogen oxides in the flue gases of up to 70% with a high completeness of fuel combustion were found. At that, the burners do not undergo significant changes when changing fuel and are distinguished by a simple design.…”

Waste-to-energy approaches, aimed at using cheap energy carriers (oil production and refining waste, etc.), require the creation of new technologies with high energy efficiency and low emissions. One of the environmentally friendly methods is a superheated steam injection (SIM) into the combustion zone. At the same time, trends in CO2 reduction and recycling make carbon dioxide more attractive to use together with, or instead of, steam. This paper experimentally investigated the possibility of upgrading SIM to steam and the carbon dioxide injection method (SCIM) or the carbon dioxide injection method (CIM), where superheated steam and carbon dioxide are supplied together or completely replaced by CO2. In the example of diesel fuel, the characteristics of the combustion of liquid hydrocarbons in the presence of a mixture of superheated steam with CO2 in a spray burner are obtained and compared. It shows that a high completeness of fuel combustion is observed for all the studied modes. The analysis of combustion product composition demonstrates that when replacing the superheated steam with carbon dioxide, the levels of CO and NOx in the combustion products increase by 25%. All the investigated regimes comply with the EN:267 standard. The results obtained show that it is possible to realize SCIM and CIM approaches for waste-to-energy with the use of CO2.

“…At the same time, it was shown in works, that the use of superheated steam can significantly reduce the content of harmful emissions in the combustion products, compared to other types of diluents. For example, the use of superheated water steam can reduce the concentration of nitrogen oxides in exhaust gases by up to 50% at high combustion efficiency of hydrocarbon fuels [3]. In works, such effect is connected with decrease in the flame temperature, due to which formation of "thermal" NOx is decreased, as well as occurring of steam gasification, which also allows maintaining high combustion efficiency of fuels.…”

In the present work, the combustion of liquid hydrocarbons sprayed by air jet was studied using diesel fuel as an example. The dependences of nitrogen oxides and carbon monoxide concentrations in combustion products on the fuel and air flow rates were investigated using an atmospheric burner device. It is shown that while diesel fuel sprayed by air jet there is a wider range of operating parameters in comparison with steam spraying due to the flameout. Compared with atomization by air jet at room temperature, steam and heated air spraying have advantages, for these regimes the NOx concentrations are observed to be lower.
