WE'RE ON FIRE FOR THE MOST EFFICIENT LIME KILNS.

The principle of the PFR kiln, i.e., the calcination of lime in one shaft and the preheating of the stone with the hot kiln gas in the other shaft, is also used in the Finelime ® kiln. Thus its heat consumption is significantly lower compared to rotary kilns. Since 1989, when it was first introduced onto the market,

Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 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 heat-up and cool-down cycles of the batch kilns.
