Renovation Practice of Waste Heat Boilers for Converters 1 and 2 at ZNIS
The waste heat boiler recovery system is a key link in converter production.With the requirements of high pro-duction,low consumption,and green development of the converter,the efficiency improvement of the converter waste heat boiler system is a technical challenge faced by steelmaking production.In response to the problems of frequent tube bursts,low steam recovery,heavy maintenance workload,and serious environmental pollution in the converter waste heat boiler,technical renovation measures such as modifying the tail flue and high-pressure deaerator of the converter waste heat boiler system,adopting new nano insulation materials,and optimizing the direction of the heat pipeline are taken to stabilize the operation of the converter waste heat boiler system,improve steam recovery,and achieve the goal of stable and safe convert-er production.
