链蓖机/回转窑燃烧控制模型优化

摘要

莱钢链蓖机/回转窑采用双闭环比值控制前馈-反馈回转窑温度来优化温度模型，实现精确配料和科学控制回转窑内温度，最大限度地防止了结圈、结块现象，每天少结块20 t，提高了球团产量，节省煤气1050 m3/h。%　　Laiwu Steel’s grate kiln adopted double-closed-loop ratio to control feed forward-feed back kiln temperature for optimizing temperature model, achieving precise batching and scientific control of rotary kiln temperature, preventing maximum sticking and blocking phenomenon, decreasing blocking about 20 t every day, increasing pellet quality, saving gas 1 050 m3/h.
