Using the vertical preheater, the calcinations process not only will shorten the time of limestone burning in the kiln, but also get a high degree of the active lime. According to the place of vertical preheater in rotary kiln system, and negative pressure working principle of Preheater.
The KVS preheater/rotary kiln calcining system is selected when a uniform, high quality lime product is required. Metso can also supply long rotary lime calcining systems, but it is the KVS preheater/rotary kiln system approach to lime calcining that is the technology of choice for the more demanding applications.

Preheater for lime calcining The Metso preheater is a proven, efficient piece of heat recovery equipment that uses the hot process gases from a pebble lime rotary kiln to preheat/pre-calcine limestone feed material prior to metering it into the rotary kiln at a controlled rate for final calcining.
Efficiency and flexibility in operations The KVS preheater/rotary kiln calcining system is selected when a uniform. to select the proper type and size of calcining equipment. or combinations of two or three different types of fuels. calcining (of both high calcium and dolomitic limestones).
Lime calcining systems Preheaters The KVS Preheater System includes an integral “live” stone storage bin. Stone flows by gravity from the bin to the preheater modules through vertical chutes, (which also provide an air seal between the process and ambient). Kiln exhaust gases enter the preheater at 1900 to 2100 Degrees F.

Metso can also supply long rotary lime calcining systems, but it is the KVS preheater/rotary kiln system approach to lime calcining that is the technology of choice for the more demanding applications.
Kiln fuel is combusted on the lime discharge end of the kiln and hot gases are exhausted on the end of the kiln where the stone enters the process. After heating and partial calcining in the pre-heater, the stone is discharged by a hydraulic ram to the pre-heater discharge opening.
In a modern, well designed preheater rotary kiln calcining system, fuel efficiency can be as low as 4 MBtu/Ton. A preheater can be added to an existing kiln of any length. By retrofitting a preheater onto an existing kiln the system efficiency can be greatly improved. In some cases the preheater is added at the feed end of the existing kiln.
