Combustion of Substandard Liquid Hydrocarbons in Atmosphere Burners with Steam Gasification

Abstract

In this research we experimentally investigated the process of liquid hydrocarbon combustion at spraying by a jet of superheated steam, using waste automobile transmission oil as an example. In the laboratory burner model (up to 20 kW) we studied the effect of mode parameters on the characteristics of the combustion process in the presence of superheated steam, namely, heat release and composition of combustion products, and flame temperature. The possibility of combustion of substandard liquid hydrocarbons in a straight-flow atmospheric burner at 10 kW is shown. Dependences of the main thermotechnical and environmental characteristics of the burner on temperature and flow rate of superheated steam and fuel consumption are found. The fuel combustion efficiency reaches 97%, observing minimal concentrations of toxic combustion products: {CO} = 20 mg/kWh{NO}_x = 60 mg/kWh, which corresponds to class 3 of EN 267.
