Vertical kiln production is often due to raw materials, defective fuel calcining kiln operation control and to determine the status of the deviation, will appear in the kiln wall tumor mass phenomenon, and even shed material phenomenon. This phenomenon can also cause the kiln wall temperature increases, there will be severe kiln wall see red, but also a refractory failure phenomenon. After this happens, must be treated, otherwise it will seriously affect the safe operation of the quality of the lime kiln and lime. Kiln shell of reinforced concrete and steel the forces green lime kiln shell the same price, but because of this kiln shell thickness relatively large steel kiln shell, and therefore needs to withstand the temperature difference between inside and outside temperature stress generated when the computer passed concrete kiln shell When the temperature should be considered complete when the brick lining and wear after two cases, because the brick lining wear will raise the temperature inside the kiln shell surface. From the perspective of temperature stress, temperature stress YU Xiao thinner reinforced concrete shell lime kiln process equipment, caused by the temperature difference, but the kiln shell is too thin is not easy to ensure construction quality. Taking into account the complexity of the kiln shell by force and to ensure the quality of construction, it is generally preferable to 150 mm thickness, when the kiln shell height is small, its thickness can be reduced to 120 mm. For mixing kiln, after anthracite coke, is the most common current use of the fuel burnt lime, particularly in construction lime plant. Anthracite coal fixed carbon content than are other types of high-volatile content of low 亦较 each other, and therefore has a high combustion starting temperature. Kiln hood door feeding lime is generally trapezoidal shape, number and size of the environmental feasibility report kiln feed doors, flat location and elevation settings, you should consider feeding, easy to play through the kiln and brazing operations and ease of handling, etc. accident, feeding door can not be too large and too small, too much effect on the structural strength of lime kiln and chimney, and kiln poor sealing, easy leakage. Feeding operation is too small is too small feeding operation inconvenient inconvenient, when feeding the dead that is prone to uneven loading. According to the actual experience of domestic production, for natural smoke, the white brick chimney ordinary kiln, usually set up a feeding door. For mechanical exhaust chimney steel side, set the number of feeding in the kiln hood door, depending on the kiln diameter, generally 1-2, up to more than three.
