2500t / d NSP kiln ring formation Analysis and Prevention

,[link widoczny dla zalogowanych], The coal mill population increased temperature from 230oC to 260oC,[link widoczny dla zalogowanych], the outlet temperature from 60 ℃ up to 65cc,[link widoczny dla zalogowanych], coal moisture control in about 1% to 1.5%, to ensure complete combustion of coal in the kiln. (3) in the smoke chamber and preheater kiln exit gas analyzer installed. Enhance the means of control. Strictly control the content of kiln smoke chamber 0 (volume fraction 12% ~ 3%,[link widoczny dla zalogowanych], CO content (volume fraction) <0.5%; if found excessive. Immediately find the cause and make adjustments. (4) strict enforcement of thin fast forward system. Three unified operation, strict implementation of the system of thin fast forward, slow the kiln is strictly prohibited aniseed, forcing the fire burned the top. In normal production time. We kiln speed from the 3.3 ~ 3.5r/min to 3 .7 ~ 3.9r/min. In addition, investment expected from the beginning of the production of normal feeding time to as short as possible (when I heat in the kiln. from the normal expected to vote around with 30rain), to avoid a long feeding period of time, the kiln speed slow, wind, coal, materials matching knot ring caused unreasonable. Liren Long: 2500t / d NSP kiln ring formation and prevention of the causes of more than 3 effective implementation of the measures adopted. I plant the phenomenon of ring formation is essentially eliminated. from change the first 3 months and 3 months after the change of production data response system after the reform of the kiln thermal stabilization, rotary kiln production and quality are more than design specifications, power consumption, coal, brick consumption to the domestic advanced level. which : (1) clinker production from 2300 ~ 2400t / d increased to 2600 ~ 2750t / d, 28d from the 56 ~ 58MPa high strength increased to 59 ~ 62MPa; (2) Results from 60 times the number of rings to 2 times, the operation rate from 70% to 91%; (3) tons of clinker power consumption dropped from 80kwh 72kwh, tons of clinker, coal consumption fell from 130t 108t; (4) transition zone and burning zone refractory bricks from 3-month life cycle Replacement extended to 12 months replacement.
