Simulation of the limestone calcination in normal shaft kilns

This article presents a mathematical process model to simulate the limestone calcination in a normal shaft kiln. The process model comprises a set of ordinary differential equations derived from .

Lime kilnWikipedia

Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient.The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.

Simulation of limestone calcination in ­normal shaft kilns

The process of calcination in normal shaft kilns can be described and simulated by means of a mathematical model in which the operating conditions, material properties and kiln geometry serve as …

Simulation of the limestone calcination in normal shaft

In principle, the normal shaft kiln is a vertical single shaft where limestone is charged at the top of the kiln and lime is discharged at the bottom. Figure 1: Schematic of a normal shaft kiln .

Lime Shaft Kiln,Cement Rotary kiln

Lime shaft kiln, which also called vertical kiln, due to the vertical position of its kiln shell does not rotate, is always used to produce the products, such as cement, refractory materials (bauxite and mullite), lime, etc.

Simulation of limestone calcination in ­normal shaft kilns

For normal shaft kilns it is described how the axial profiles of the surface and core temperature of the stones, their decomposition and the gas temperature depend on the process parameters, which are stone size, energy input, throughput and type of fuel.

Energy and exergy analysis of an annular shaft kiln with

In current industry practice, there are several types of kilns commonly used for lime burning; including the rotary kiln, the normal shaft kiln, the Maerz kiln and the annular shaft kiln. Among all these kilns, the annular shaft kiln has been widely adopted with the advantage of being able to produce lime with various reactivities [1] , [2] .
