Channel temperature of the kiln lime plant

Nov 28, 2016 OPERATING A LIME KILN Exhaust Gas Temperature. The exhaust gas temperature in chain equipped kilns ranges from 300 to 550 F, depending on the particular installation. A few days’ operation will indicate the average temperature for normal operation. Watch the recorder. Any unusual temperature rise may indicate that the kiln feed has stopped

    Lime recovery kilns can be as long as 380 feet and as wide as 15 feet in diameter. These vessels are refractory lined and typically zoned into five major sections including the chain section, tumbler section, intermediate zone, burning zone, and refractory dam. The operating environment in each section varies and dictates refractory selection

    Rotary Kiln Maintenance Procedures

    A kiln should be aligned when it is in operation for four very important reasons: 1. A straight cold kiln has a measurable misalignment at operating temperatures. This is because the shell axis elevation increases by one half of the thermal expansion of the shell diameter. This expansion is the function of the shell temperature and, as such, it

    Because the kiln is the hub of the lime plant, it is necessary to monitor the level of the limestone inside the kiln during operation. Through limestone level monitoring, the operator can adjust kiln operation (i.e., adjust waste gas outlet temperature or fine-tune the quicklime discharge system)
