Some shaft kilns can be operated on natural gas, liquid and solid fuels.This type of kiln tends to produce medium reactivity quicklime, which can then be used in a number of industrial processes including the manufacture of iron and steel and aerated concrete blocks.Quicklime from shaft kilns is also processed into hydrated lime.
The so-called multi-fuel-fired normal shaft kiln nsk is one of the oldest types of lime shaft kiln, in which burnt lime is produced from limestone by expelling the carbon dioxide gas.This type of kiln is fired with lumpy solid fuels.Due to this mode of firing, operation of the kiln has special characteristics that result in complex process.
The result is the convergence of a unique constellation and concentration of lime shaft kiln expertise.In addition to our own product palette, eberhardt schwab is now able to build, optimise and modify all shaft kiln types and systems mixed-fuel kilns, multi-chamber furnaces, ggr kilns, annular shaft kilns, etc.
In view of the low production capability and high energy consumption with the gas - burning shaft lime kiln used in metallurgical works, a double pre- heating technique is employed in the shaft kiln, which is recently completed at sisg and coupled with a metal-tube.
This paper introduces the features of limes activity, simulates the lime kiln of shaft furnace by using 2d mathematical model, discusses on the simulation results, and indicates that the unreasonable blast-cap structure is the main reason of causing the low activity of the lime.
Operations strategies for vertical shaft lime.The next common type of kiln is the vertical shaft kiln.This kiln can be described as an upright heavy steel cylinder lined with refractory material.The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln.
