British Lime Association (BLA) part of the Mineral

In the UK, lime is manufactured using two types of gas-fired kiln; vertical shaft kilns and parallel flow regenerating (PFR) kilns. PFR kilns are widely considered to be the most energy efficient. Vertical shaft kilns use similar technology and processes but are less efficient.
