A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for .

clinker and gypsum. Additionally, clinker is produced through a combination of lime‐ stone and minor amounts of clay. In India to reduce clinker factor, supplementary cementitious materials (SCM's) fly ash and blast furnace slag are commonly used. In fact, a majority of the cement produced in India is PPC or Portland Pozzolana cement

Slaglime cements—ground granulated blastfurnace slag is not hydraulic on its own, but is "activated" by addition of alkalis, most economically using lime. They are similar to pozzolan lime cements in their properties. Only granulated slag (, waterquenched, glassy slag) is effective as a cement component.

The consumption of fuel in the blast furnace with the limestone flux, amounted to 38 cwts. on the ton of pig metal produced; with burntlime it was 36'5 cwts. to the ton, showing a diflbrence of about 4 per cent. in favor of the burnt lime.

A blast furnace is a special type of furnace for smelting iron from furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in blast furnace is the biggest chemical furnaces are also called high ovens..

The calcined ore is mixed with lime stone (CaCO 3) (Flux) and ore in the ratio of 8:1:4 and charged into blast furnace. The blast furnace is cylindrical steel vessel limed 6m in diameter. The blast furnace is cylindrical steel vessel limed 6m in diameter.

Lime stone and dolomite when charged in the blast furnace gets calcined inside the blast furnace. Decrease of silicon content in the hot metal by 1 % improves the coke rate by 5 % to 15 %. pellets and calibrated iron ore (CLO).
