The common evaporative stabilizer structure is provided with an evaporation tube, and when the afterburner is in a small afterburning working state, a small part of fuel oil is directly supplied into the evaporation tube. The fuel oil is acted by wall surface heat in the evaporating pipe, most of the fuel oil is evaporated into gas and then is sprayed out from the small holes of the evaporating pipe, so that the fuel oil is uniformly distributed in the radial and circumferential ranges of the stabilizer, and the aims of promoting atomization, evaporation and mixing of the fuel oil are fulfilled.
