Abstract
The characteristics of combustion of liquid hydrocarbons in the presence of a mixture of superheated steam with a diluent gas in an evaporative burner are studied by an example of diesel fuel. Carbon dioxide is used as a diluent gas. The experiments reveal regimes of injection of superheated steam or carbon dioxide, as well as their mixture in various proportions, that ensure similar profiles of the mean flame temperature, thermal power, and air-to-fuel ratio. It is demonstrated that fuel burning in the presence of superheated steam, carbon dioxide, and their mixture allows reaching low concentrations of CO and NO\(_{x}\) in combustion products. In the case of CO2 injection, these values are at the boundary of admissible concentrations for class 3 in accordance with the EN:267 standards. In the case of injection of only superheated steam, nitrogen oxide emissions in flue gases are smaller than those in the case of carbon dioxide injection: reduction of NO\(_{x}\) emissions can reach 15%.
