摘要
A method for oxy-fuel combustion, the method comprising the steps of: introducing a liquid fuel (20) into an emulsion chamber (10) through a liquid fuel conduit (31) having an effective diameter (14), the emulsion chamber having a length (13) that is 2 times or less than 2 times of said effective diameter (14) of said liquid fuel conduit (31); introducing an atomizing gas (21) into the emulsion chamber (10) through at least one atomizing gas conduit; mixing the liquid fuel and the atomizing gas in said emulsion chamber (10) to create an emulsion mixture that has a mean residence time in said emulsion chamber of from 500 to 800 µs, the emulsion mixture having an emulsion mixture velocity less than or equal to 12 m/s; and discharging said emulsion mixture through a generally rectangular-shaped orifice (11) into an oxygen-enriched oxidizer stream: A nozzle and burner for oxy-fuel combustion are also disclosed.
