A "vertical lime kiln" is a type of industrial furnace or oven used for the high-temperature calcination of limestone (calcium carbonate) to produce quicklime (calcium oxide). Unlike traditional horizontal kilns, vertical lime kilns have a vertical orientation, and the limestone feed is introduced from the top, while the combustion of fuel and the production of quicklime occur in the lower part of the kiln.

The key purpose of a vertical lime kiln is to heat the limestone to a temperature high enough to facilitate the chemical decomposition of the calcium carbonate into calcium oxide and carbon dioxide. The quicklime produced in the kiln is a vital component in various industrial processes, including metallurgy, construction, and water treatment.

Vertical lime kilns are often preferred for their energy efficiency and relatively small footprint, making them suitable for a range of applications where quicklime is required. These kilns can be operated using different types of fuel, such as coal, natural gas, or other suitable combustible materials, depending on the specific requirements of the lime production process.

A vertical lime kiln is a stationary, vertical, cylindrical lime kiln that encompasses both mechanical shaft kilns and regular shaft kilns. Ordinary shaft kilns involve either manual feeding and unloading or mechanical feeding and manual unloading. In contrast, mechanical vertical lime kilns are employed for both mechanical feeding and unloading. Mechanical vertical kilns, when compared to regular vertical kilns, run continuously and deliver higher output, better quality, and improved labor productivity.

In recent years, China has made significant progress in the development of fully automatic, mechanized, environmentally friendly, and energy-efficient active lime kilns. These kilns are approaching the advanced kiln type indicators of foreign countries.
