(1) reducing the amount of wind pressure and the fire floor down, such as the top of low pressure may be appropriate top pressure. (2) increase the amount of cinder, due to increase fuel ratio, lime kiln, heat loss supplement is not restored to normal when the top temperature is high due to normal after adjustment for normal. (3) examine and adjust the size of the original fuel. The fuel content limit excessive powder, may be appropriate to add the water to saturation, so that they increase the degree of cohesion stone to delay the fuel burn time. Firing zone down, wind, fire, when finding the top temperature is low, gray temperature rise, serious and wind unburnt fuel. The same raw lime burning increased while reducing CO2 concentration which shows a firing zone down. The main reason for this situation is the small amount of wind, Shangshih volume, cinder large, so mixing down faster, and shorten the cooling zone, failed to sufficiently preheated air will enter the firing zone, leaving the amount of calcium carbonate decomposition reduction, CO correspondingly reduced. Cause an increase in the amount of burned lime green. Another is the raw material crushed or size bias large deviation increase resistance kiln, lime kiln advanced equipment, this time pressure is not low, but the actual amount is not enough wind. In such cases should be appropriate to reduce the amount of loading and unloading stone ash, lime kiln construction, and appropriately increase the amount of wind, so when the top pressure is too large, may be appropriate to reduce the material batch, changing the material partial pieces, the appropriate increase in large grain blocks ratio, reducing grain differential, so the kiln resistance decreases. Adjustment of fuel and stone blocks to make it meet the technical requirements. Blast furnace maintenance and shutdown: continue for a long generation furnace served, its equipment, structure, lining be worn in production, some way in need of repair, and some want to break wind, building lime kiln, and some want to shutdown to be replaced Such work is called maintenance. Access by time and nature can be divided into four categories: temporary maintenance, preventive maintenance, repair and overhaul. A temporary repair and regular maintenance overhaul mainly refers to temporary change vents and small slag tap, also including small repair work must address. Temporary access to off the wind, the wind off the program on short-term operations. To replace the air when regular maintenance or in large sets of sets, air pipe, part of the furnace body cooler, skip, hot air valve, distributor, etc. Periodic maintenance time is short, there are more than ten hours, up to several days long, so long off the air by the blast furnace process. Second, in the repair and overhaul of heavy maintenance work, can not be processed in time during routine maintenance, it should be carried out in a blast furnace repair. In the repair projects are: repair, relining, replace the upper cooler, replace distributor, hoist rope wheel. In the generation furnace process, repair once or twice normal. The repair time required for five days to a month, with the workload varies. The repair of the blast furnace to be shutdown, but hold residual iron. Are hearth furnace charge to hold in addition, depending on whether the replacement hearth brick lining and cooler. Overhaul including the replacement of all lining (especially the bottom), the replacement of one or all of the metal structure, expanding blast volume and the like. Overhaul time to be 30 to 45 days, medium-sized blast furnace is 25 to 40 days. _ _ Blue sky kiln lime kiln construction furnace (view) provided by LUOZHUANG Kiln Ltd. Linyi City blue sky.
