two pulverised coal fired, rotary lime kilns producing burnt and hydrated lime for a variety of customer bases including the gold, steel, roading and water treatment industries. Each kiln uses approximately 100 tonnes of coal per day producing in excess of 400 tonnes of carbon dioxide. The decomposition of limestone in each kiln

The kiln model applied in this work was developed by Hatch over a number of years and has been used for several rotary kiln projects. It has its roots in a FORTRAN program that was developed by Venkateswaran (1978) to study the reduction of iron ore. The original software was used to model the operation of a 35 m pilot kiln at the Stellco company

Rotary kiln drives the cylinder body to rotate through transmission device and continues to be heated at high temperature to meet the heat transfer requirements of each stage of the clinker formation process and the requirements of heat, temperature and time for the formation of different minerals as well as physical and chemical reactions.

Beginning in the '20's, efforts were directed toward lime recovery installations. Today, a proper Rotary Lime Kiln Operation is an integral part of all modern pulp mills. How a Rotary Lime Kiln Works Kiln Feed and Feeders High quality lime can be produced at a uniform rate only if the kiln is fed at a constant rate with lime sludge [.]

The prevalent type of kiln is the rotary kiln, accounting for about 90 percent of all lime production in the United States. This kiln is a long, cylindrical, slightly inclined, refractory-lined furnace, through which the limestone and hot combustion gases pass countercurrently. Coal, oil, and natural gas may all be fired in rotary kilns.

Practice has proved that to ensure the long-term safe operation of rotary kiln, the following three aspects should be carried out: 1. Operation . Hanging and protecting the kiln skin is one of the main measures to ensure the long-term safe operation of the kiln.In order to protect the kiln skin, the following measures should be taken:

Selecting the Proper Lime Kiln Technology. Lime is a key industrial mineral used as a chemical additive by many industries. The industrial facilities that utilize Lime in various forms are metal ore processing, metallurgy, steel, paper, pharmaceuticals, sulfur removal, and water treatment.

of the entire kiln operation. 2.0 Theory 2.1 Types of kiln Kilns employed for burning lime may be divided into two classes[4] : intermittent kilns and continuous kilns. The latter class in turn may be sub-divided into rotary and shaft kilns. The shaft kilns may again be sub-divided into mixed feed and separate feed kilns.
