Combustion of sub-standard liquid hydrocarbons dispersed by a superheated steam jet

This paper by the example of spent automobile transmission oil investigates the combustion of sub-standard liquid hydrocarbons in a straight-flow burner, implementing a promising method of liquid fuel dispersion by a superheated steam jet. The aim of the work is to study the influence of regime parameters on the thermal and environmental characteristics of the combustion process. Gas composition of combustion and heat release products was measured. A flow calorimeter was used to measure heat release. The measurement of the amount of generated heat was based on determining the coolant temperature difference at the inlet and outlet as well as the flow rate of the coolant and fuel under stationary experimental conditions. TESTO 350 gas analyzer was used to control the composition of gaseous combustion products. Sampling of reaction products cooled to room temperature was carried out at the calorimeter output. Dependences of specific heat release on steam and fuel flow rates have been obtained. The regimes with low CO content in the combustion products have been found.
