Parallel flow regenerative (PFR) kilns. The PFR kiln is a very efficient shaft kiln composed of 2 or 3 shafts interconnected by a central crossover channel. Energy is supplied via lances that are plunged into the charge. Some kilns are fitted with 19 lances, whereas modern kilns are fitted with 33 lances in each shaft.

kiln: two burning shafts with a rectangular or hexa - gonal cross section are placed next to each other. Through a direct crossover channel the combustion gases flow from one shaft to the other. The rect- angular cross section simplifies the fabrication of the kiln by imposing fewer challenges on the steel con - struction and the refractory material.

A lime manufacturer operates a 300 tons per day Parallel Flow Regenerative Kiln (PFRK), fired with natural gas. The kiln is fed with 40-80 mm limestone, but in order to maximize the use of the quarry reserve, the company wished to explore the possibility to feed the kiln with smaller and coarser particle size distribution.

Twin ShaftProcess Regenerative The Cimprogetti TSR is a two-shaft vertical kiln which utilizes the regenerative process for lime calcination. When one shaft operates in the burning mode, the other shaft operates in the regeneration (non-burning)mode. Each shaft operates for an equal amount of time in theburningandregenerationmodes.
