Ultra-high temperature ultra-high temperature shaft kiln shaft kiln for calcining high purity refractory material, and the majority of alkaline material, kiln temperature up to 1900 ℃ -2000 ℃. Now the country has been put into use in ultra-high temperature shaft kiln main performance: effective volume: 3.5m3-19m3; kiln inner diameter: φ700mm-φ1600mm; production capacity: 700t / a-50000t / a; unit of product heat consumption: 2000kJ / kg-2500kJ / kg. Ultra-high temperature shaft kiln utilization coefficient, and high productivity. Actual production, furnace utilization factor of up to 5t / m3-7t / m3d, part of the furnace up to 7t / m3d-10t / m3d. The main technical measures to achieve ultra-high temperature are: the kiln secondary air to make good contact with the material, to fully absorb the physical heat the material, before entering the calcining zone temperature has reached above 1500 ℃. At the same time the fuel is injected into the kiln through the burner directly on the hot material SAIC of combustion, high combustion efficiency, the furnace temperature coefficient of up to 0.9. (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, supplementary heat loss 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 amount of wind lime kiln drying kiln Oscar altar, Shangshih volume, cinder large, so mixing down faster, and shorten the cooling zone, failed to sufficiently preheated air will enter the firing zone Jintan lime kiln drying kiln, leaving the calcium carbonate decomposition to reduce the number of Jintan lime kiln drying kiln, CO is reduced accordingly. Cause an increase in the amount of burned lime green. Another is the raw material crushed or size bias large deviation increase kiln resistance, 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 content, and appropriately increase the amount of wind Jintan lime kiln drying kiln, so when the top pressure is too large, the material may be appropriate to reduce the grant, the changes of the partial pieces of raw material, due to increase a large proportion of grain block, reducing grain differential, so the kiln resistance decreases. Adjustment of fuel and stone blocks to make it meet the technical requirements. Lime kiln project, Jintan lime kiln, kiln blue sky by LUOZHUANG Kiln Ltd. Linyi City blue sky.
