Description
technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for calculating the depth of a blast furnace tuyere swirl zone. Background technique [0002] The blast furnace is a complex counter-flow reactor. The high-temperature and high-pressure hot air blown from the lower part of the blast furnace reacts with coke in the tuyere swirl area to generate a gas flow. During the rising process, the gas flow exchanges energy with the ore added to the upper part of the blast furnace, and a reduction reaction occurs to generate molten iron and slag. The tuyere swirl area is an important reaction area indispensable for the stable operation of the blast furnace. The depth and reaction conditions of the tuyere swirl area of the blast furnace directly affect the gas distribution of the blast furnace, the charge drop, and the heat and mass transfer process of the entire blast furnace. [0003] In the prior art, the Euler mode...
