Coal fired vertical kiln uses a mixture of limestone and coal at proper ratio for calcination. Our environmental friendly mechanical vertical kiln designed with airtight top sealing structure, automatic disc outlet mechanism at bottom, exhaust gas outlet designed with threestage desulfurization and dust removing system, significantly reducing emission of dust and SO2.
In a shaft kiln, the limestone | dolomite moves counter flow to hot gases in the shaft. This gives shaft kilns the lowest fuel consumption of any type of calciner. The shaft refers to a vertical vessel where the calcining takes place.
Kilns are normally fired with pulverized coal or gas at one end. Raw materials are fed to the kiln at the back end, furthest ... much longer to allow enough time for drying before calcination. Lime or quicklime are the common names for calcium oxide (CaO), a graywhite powder. ... to a rotary or vertical kiln where carbon dioxide is driven off to
Calcination is an endothermic process and the required heat energy is supplied usually by firing coal along with the lime stone. There are heaped and rectangular trenched kilns commonlyknown as country kilns, vertical shaft kilns of KVIC designed and CBRI designed vertical shaft country kilns and Belgian vertical shaft kilns. The limestone to ...

Vertical lime kiln, just like its name, the shape is erect. It is used for calcination limestone. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, it was widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.
In a flare kiln, a bottom layer of coal was built up and the kiln above filled solely with chalk. The fire was alight for several days, and then the entire kiln was emptied of the lime. In a draw kiln, usually a stone structure, the chalk or limestone was layered with wood, coal or coke and lit.

Physical Properties of the Limestone and Lime: Although the fuel efficiency of vertical kilns is much higher than that of rotary kilns, limestone could break down into smaller pieces during calcination due to the "decrepitation" phenomenon which clogs vertical kilns, making the process not feasible. Likewise, the lime created during the ...
