“…Based on the proposed combustion method, low-emission liquid fuel burners of various designs were developed and tested for the disposal of liquid combustible waste. 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.…”

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.

“…Kerosene combustion in a burner with a jet of superheated steam was studied with the help of an experimental setup used in [17]. The setup consists of: burner; water supply system (flow rate Fv = 0.2 ÷ 1.4 kg/h); electric steam generator (steam overheating degree Ts of up to 400 degrees); air supply system, instead of steam (flow rate Fair = 0.3 ÷ 1.2 kg/h); system for liquid fuel supply and heating (fuel flow rate Ff = 0.4 ÷ 2.2 kg/h) (see figure 2).…”

“…The experimental setup for studying the soot-steam combustion of liquid hydrocarbons is part of the unique research facility USU "Large-scale thermohydrodynamic setup for studying the thermal and gas-dynamic characteristics of power plants" [18]. To plot a regime map of burner operation during the combustion of kerosene sprayed with superheated steam, a flow-through calorimeter with installed Testo 350 gas analytical equipment was used [17]. To study the flame temperature in the selected regimes, we used a platinum-rhodiumplatinum-rhodium thermocouple of type B (wire diameter of 0.3 mm) mounted on a coordinatemoving device to determine the average flame temperature along the flame symmetry axis.…”

In the present work, the effect of forced air supply on the combustion process of liquid hydrocarbons was studied using diesel fuel as an example. The content of the flame intermediate components and temperature distribution along the flame symmetry axis were studied using an atmospheric burner in which liquid fuel is atomized by a steam jet. The gas composition of equilibrium combustion products and heat release were also investigated. The influence of the excess air ratio in the combustion chamber of the burner device on the thermal and environmental characteristics was shown.

“…The result was a burner that produced an almost flame‐free combustion, and they also indicated that less than 15 mg/Nm 3 NO X and less than 5 mg/Nm 3 CO emissions were produced. Anufriev et al [ 9 ] studied a new burner to achieve low NO X emissions. In this study, they used a steam burner and intended to burn diesel and waste oil.…”

A fuel/oxidizer mixture can be burned using a colourless distributed combustion (CDC) process to obtain low emissions and homogeneous combustion. As an alternative way, a perforated burner can be designed to achieve homogeneous combustion and low emissions without changing the combustion performance by having entrainment effects on the combustion chamber. In this study, computational fluid dynamics (CFD) 3D modelling was performed in a perforated burner for ammonia/methane fuels in order to obtain the distributed regime and focus on the entrainment effects. In numerical analysis, the eddy break‐up was used as combustion model, k‐Ɛ as turbulence model, and P‐1 as radiation model. In this study, 10% and 20% entrainment rates were provided from the flame holder wall of the perforated burner. The effects of entrainment rates on temperature, velocity, and NOX emission values were examined. According to the results, when the entrainment rate was increased from 10% to 20%, the overall temperature values of ammonia and methane combustion slightly increased by approximately 1.0%, while on the other hand the maximum temperature levels in the near burner zone decreased by about 5.0%. The findings demonstrated that temperature and velocity distributions got more uniform and the flame zones became thinner. This provided a more colourless and invisible flame appearance. In this way, an improvement in the thermal field has been achieved. In conclusion, when the effect of the distributed regime on NOX emission levels was examined, it has been noted that entrainment effects enable the achievement of low emission levels (approximately 9.0%).
