A PFR kiln (parallel flow regenerative shaft kiln) consists of two vertical shafts and a connecting crossover channel. Both shafts work with each other. While one calcines the product, the other preheats the stone. In the burning shaft the lime is calcined in parallel flow. The hot combustion gases are then
Annular Shaft Kiln The major feature of the annular shaft kiln is a central cylinder which restricts the width of the annulus, and ensures good heat distribution. The central column also enables part of the combustion gases from the lower burners to be drawn down the shaft and to be injected back into the lower burner chamber.
Annular Shaft kiln inner structure from top to bottom is preheating zone, uppercounterfollow calcining zone, lowerparallelfollowcalcining zone,and cooling / discharge zone. Raw material is screened firstly, then . transferred to the top of the kiln by the hoisting hopper,and then feed into the kiln body by the rotary . distributor evenly.
Kiln feed is fed into the Cyclone duct. Preheating and Calcination takes place in various stages of Cyclones due to heat transfer. Fine Coal is fired from Kiln outlet and through a Burner pipe. The hot gases generated due to fine coal firing are taken out by ESP Fan through Preheater and ESP. Heat transfer takes place in Preheater as Kiln feed
Several different types of kilns are used for the calcination process. These kilns can be rotary kilns or shaft kilns. The type of the kiln to be selected strongly depend on the characteristics of the limestone, anticipated production rate, cost of fuel, investment costs, available fuel, local conditions, infrastructure and other things.

kilns have satellite coolers, no preheaters and are protect ed from the weather by a common building enclosure. Kiln 5 is the largest kiln at 12 ft dia. x 405 ft long with the front 75 ft of the burning zone flared to 13 ft dia. All five kilns are direct coalfired with Raymond bowl mills. The oldest part of the plant is the kilns 1 to 4 area.
