Experimental Study of Kerosene Combustion with Steam Injection in Laboratory Burner

and environmental parameters were measured during kerosene combustion at injection of superheated steam into the combustion zone. The studies were carried out in a laboratory burner, i.e., a new method of combustion of fuel sprayed with steam was implemented. Experimental data have been obtained for various concentrations of steam in the mixture with the fuel. The content of toxic substances in the exhaust gases was reduced due to the steam injection: up to 70% for CO and up to 95% for NOx. The parameters of kerosene combustion for regimes with spraying by jets of superheated steam and heated air were compared. The advantages of the proposed method of combustion with steam have been shown. Minimum emissions of 0.11 g/kg for CO and 0.89 g/kg for NOx at a high combustion efficiency of kerosene of similar to 44.5 MJ/kg and a power of 15- 18 kW have been achieved at a steam concentration of 36%; they meet the environmental standard EN 267. The results obtained indicate effectiveness of steam application for reducing emission of toxic combustion products at kerosene combustion. Experimental data are needed to verify the results of numerical simulation in the calculation of low-emission combustion chambers.

Automated summary

This study investigated the effects of injecting superheated steam into the combustion zone during kerosene combustion. Experimental data showed that injecting steam resulted in a significant reduction in toxic emissions, with up to 70% reduction in CO and up to 95% reduction in NOx. Comparisons were made between kerosene combustion with steam and heated air. The proposed method of combustion with steam demonstrated advantages, achieving minimal emissions of CO (0.11 g/kg) and NOx (0.89 g/kg) while maintaining high combustion efficiency. These findings are important for the design of low-emission combustion chambers.
