Overheating turbine generating system for recovering sensible heat of converter gas

The invention relates to a residual heat utilization technology of converter gas, in particular to an overheating turbine generating system for recovering sensible heat of converter gas, comprising a steelmaking converter, an evaporative cooling flue, a high temperature-resistant dust remover, a residual heat boiler, a refined dust remover, a steam pocket, a turbine and a generator. 1600 DEG C converter gas generated by the steelmaking converter sequentially passes through the evaporative cooling flue, a diffusion type cyclone dust remover and the residual heat boiler and then enters the refined dust remover after being cooled to below 200 DEG C, and the back part of the refined dust remover is connected with a gas recovering and discharging device; and an overheater arranged in the evaporative cooling flue transforms steam separated out of the steam pocket into overheating steam with the temperature of 350-400 DEG C and the pressure of 1.5-2.5 MPa, and the overheating steam enters the multi-inlet overheating
