Mixing apparatus with outlet nozzle and uses thereof

摘要

An apparatus and process for the atomization of a combustible material comprises feeding at least one stream of the combustible material and at least one stream of an auxiliary gas, under pressure, through an elongated zone in which atomization of the combustible material is achieved by expansion of the auxiliary gas while causing the said streams frequently to split into partial streams, recombine, and changing their rotational flow pattern throughout substantially the whole length of the zone; and adjusting the feed of the said auxiliary gas and combustible material into the atomization zone such that the atomized product from the zone is one in which the auxiliary gas occupies an appreciably greater volume than that occupied by the combustible material. At the zone outlet is provided a nozzle for constraining the atomized combustible material in a desired predetermined profile. There is substantially no atomization of the fuel by the auxiliary gas prior to entry into the atomization zone.
