Ultra-high temperature ultra-high temperature shaft kiln shaft kiln for calcining high purity refractory material, and the majority of Wuxi alkaline material kiln construction, 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 by kiln burner construction materials directly SAIC of hot combustion, high combustion efficiency, the furnace temperature coefficient of up to 0.9. Fourth, nodulation, nodulation is mixed with the gas kiln firing kiln including the biggest failure, then can be found in (1) often at high temperature ash, lime simultaneous unloading students burned, the CO2 content of the gas kiln partial long time Low (2) the material surface height and cinder amount does not match, the material in the kiln residence time is shortened, but prolonged cinder, ash mixed with unburned fuel and uncalcined limestone appears to form a green ash. The main reason is that it (1) fuel ratio is too high, or too many impurities in the fuel, generated fusible material. (2) the ratio is not high, but fuel locally concentrated Pizhou kiln construction, calcining kiln wall material strong form (3) can not properly produce or prolonged power outage Jiangsu kiln construction, kiln residence time in the hot zone too often or impurities easy to form a tumor block component is present. Should (1) When this happens adjust fuel ratio, top pressure adjustment Pressure Reducing raw fuel impurities. (2) reduce the quantity or an increase in the dumping of ash, reducing the material surface height so the tumor mass or hanging material exposed by the cooling and feeding the impact it off. Small blast taking serious measures. (3) changes in the fuel mix and the original fabrics inequality, avoid excessive local fuel. (4) increase the frequency of feeding and discharging ash to increase the flow of the material times, to avoid sticky materials linked to the phenomenon of state.
