Fourth, nodulation, nodulation is mixed with the gas kiln firing kiln including the biggest failure, then can be found in (1) ash high temperature constantly, Shandong environmental protection lime kiln, lime simultaneously discharged raw burning kiln gas CO2 content is low for a long time (2) the material surface height and cinder amount does not match, the material in the kiln residence time is shortened, but the cinder prolonged, the cost of environmental protection lime kiln 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. Easy to form a tumor mass (2) the ratio is not high, but fuel locally concentrated, intense calcining kiln wall forming material (3) is not normal production outage or a long, hot zone residence time in the kiln too often or the presence of impurities. 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 amount of cinder, Jingjiang environmental protection lime kiln, reduce stock level, so that 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. The product structure rationalization of fuel combustion of fuel should not contaminate the product, or the degree of pollution in the quality of products within the allowable range. Therefore, when the calcination and firing high concentrate products, coal burning kiln environment, we must insist on the use of low-ash high calorific value gaseous fuel or liquid fuel. Because of China's unit GDP occupied by the fuel is too high, resulting in shortage of fuel resources, relatively speaking, coal, less oil, blast furnace, coke oven, converter gas recovery, etc. inadequate use. From our actual situation, the focus of the work carried out: 1) the development of efficient coal preparation equipment, application of anthracite powder as kiln fuel; 2) utilization of coal resources, coal-water slurry as a refractory kiln fuel (> 1350 ℃ ); 3) the development of both the use of gas fuel and solid fuel, high calorific value and low calorie ene ene feed material and oxygen-enriched with two or with three burner technology.
