At the present stage, the waste heat utilization approach of the high-temperature and high-pressure coal gas in China only adopts the clean coal gas after dust removal to send to a TRT turbine device for power generation, and the high-temperature sensible heat of the blast furnace gas is not effectively utilized. The herringbone pipeline is mainly adopted for natural cooling, then wet dust removal or dry dust removal is carried out, the clean gas after dust removal is sent to a TRT turbine device for power generation, and the low-parameter clean gas from the TRT turbine device is returned to the steel process for recycling. Because the temperature of the clean gas after wet dedusting is only 80 ℃, the clean gas has adverse effect on the power generation of a subsequent TRT turbine device, has low power generation efficiency and is gradually replaced by dry dedusting. Compared with wet dust removal, the blast furnace gas adopts dry dust removal to improve the generated energy by 30 percent, and the TRT power generation turbine efficiency is improved by 10 percent when the gas temperature is increased by 10 ℃. However, the temperature increase has certain limitation, and because the inlet temperature of a bag-type dust remover adopted by dry dust removal cannot exceed 250 ℃ at most, if the temperature of coal gas is higher than 250 ℃, the bag becomes brittle and even burns. Therefore, the sensible heat at high temperature of the blast furnace gas above 250 ℃ cannot be effectively utilized, and the utilization rate of the traditional waste heat utilization device is not high, so that the problem of effectively utilizing the residual heat of the high-temperature and high-pressure gas is urgently needed to be solved.
