Luca Sarandrea Cimprogetti Italy discusses high capacity lime kilns fired by lean gases and the successful commissioning of three such kilns for JSW in India

A pilot twin shaft lime kiln of 15 ton per day capacity was employed in the evaluation It was shown that low firing rates of the burners affects negatively the kiln throughput and very low drafts lead to excessive backfiring of the burners

are their twin shaft vertical kiln that comes with multiple firing lances for fuel injection and an interconnecting section for hot air transfer between the shafts This Twin Shaft Regeneration design is more fuel efficient due to better heat transfer and containment Cimprogetti kilns are also designed in

Shaft kilns The theoretical heat the standard enthalpy of reaction required to make highcalcium lime is around 315 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 heatup and cooldown cycles of the batch kilns

The special geometry of this kiln and the special charging of the feed material guarantee ideal heat distribution even when processing smallgrained stone The principle of the PFR kiln ie the calcination of lime in one shaft and the preheating of the stone with the hot kiln gases in the other shaft is also used in the Finelime kiln
