A PFR kiln (parallel flow regenerative shaft kiln) consists of two vertical shafts and a connecting crossover Energy optimisation of vertical shaft kiln operation ,The essential part of the refractory materials production on a basis of sintered dolomite as raw material is the process of dolomite calcination. The technology process usually takes place in shaft or rotary kilns, where the dolomite stone, CaMg(CO3)2, is subjected to a high temperature heat treatment. The calcination of the dolomite is highly endothermic Annular shaft kiln for lime burning with kiln gas recirculation,Recently, the influence of vertical temperature profile in an annular shaft kiln on the calcination process has been experimentally measured and analysed,. Since Beckenbach’s invention of annular shaft kilns in the 1960s, quite a few successful adaptations to suit various fuels and raw materials (lime types) have been introduced [14]

    2.5 Vertical Shaft Brick Kiln (VSBK) This technology has been produced by China and these are in the form of a rectangular stove. The gap between the furnace wall and the outer wall of the furnace is filled with rice husk or clay. This technology consumes less fuel and produces less gas. VSBK has been running for many years.ENERGY OPTIMISATION OF VERTICAL SHAFT KILN ,Description of the technology process in shaft kiln The calcination of dolomite stone, which is one of the main stages of the sintered dolomite manufacturing, is chemical process which proceeds in a vertical shaft or rotary kiln. When heated, the dolomite decomposes according to the following endothermic reaction: CaMg(CO 3) 2 CaO + 11.17 Lime Manufacturing US EPA,The next most common type of kiln in the United States is the vertical, or 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. A primary advantage of
