The manufacture of quicklime in lime kilns a history and

produced one after another because it would waste fuel to fire the kiln from cold each time. Most of the quicklime produced from these early kilns was consumed locally. David Johnson, in his book on Limestone Industries of the Yorkshire Dales, describes how he has identified kilns of this type in the Craven area built between 1440 and 1700.

tower. Lime slurry is more alkaline, having a pH of 12.5 while limestone slurry is roughly neutral. A lime based system will therefore add more lime when pH drops below 12 and a limestone based system will be controlled around 6. Unless one or the other is added, the SO 2 gas will quickly drive the pH acidic. The calcium compounds produced in
