Opposite each hearth are burners mounted underneath arches. the products of combustion and
Lime kiln . Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient.The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.

2.1 Types of kiln Kilns employed for burning lime may be divided into two classes[4] : intermittent kilns and continuous kilns. The latter class in turn may be sub-divided into rotary and shaft kilns. The shaft kilns may again be sub-divided into mixed feed and separate feed kilns.
As the designation 'synthesis kiln' already indicates, the core of the kiln concept is the synthesis of various construction advantages of lime kilns in one design. QualiCal kilns are double-shaft-kilns that are distinguished, amongst other things, by varying geometries of kiln height.
Lime shaft kiln, which also called vertical kiln, due to the vertical position of its kiln shell does not rotate, it is known as vertical kiln or shaft kiln. Vertical kiln is always used to produce the products, such as cement, refractory materials (bauxite and mullite), lime, etc.
For larger capacities, e.g. from 300 to 800 tons per day, kilns of circular cross section are mommended. These kilns have circular ring channels collecting the combustion gases before they enter the non- burning shaft via the crossover channel, as illustrated in Fig. 7. The gases exit the burning shaft and enter the non-burning shaft radially

Low-reactive burnt lime is used for the production of sand lime bricks, aerated concrete bricks and aerated concrete blocks. Previously, no modern shaft kiln was really well adapted to the production of low-reactive burnt lime. This is why Maerz designed, constructed and patented a new single-shaft kiln, the HPS kiln (high-performance shaft kiln).
Alibaba offers 4,144 vertical shaft lime kiln products. About 96% of these are cement making machinery, 1% are industrial furnace, and 1% are drum drying equipment. A wide variety of vertical shaft lime kiln options are available to you, such as free samples.
In the shaft kiln system, taking the double-chamber shaft kiln as an example, its lime cooling device adopts central and peripheral annular cooling, and the central cooling air cap adopts tower structure to ensure uniform and smooth ventilation, so that the cooling air can better absorb the physical sensible heat of lime.
