200 tons lime shaft kiln

Description

Brief Introduction of 200 Ton Lime Vertical Kiln

At present, the lime shaft kiln with 200 tons per day is one of the most popular single kilns. The main reason is that its output is not large and its investment is relatively small. So many owners who have just started the lime calcination industry and have insufficient funds usually choose the lime shaft kiln with 200 tons per day. So if you are interested in the lime shaft kiln with 200 tons per day, you can choose the lime shaft kiln with 200 tons per day. Take a close look at the detailed introduction of 200 tons of lime shaft kiln per day.

200 tons lime shaft kiln technology

The technology of lime shaft kiln with 200 tons per day is the same as that of other lime shaft kilns. However, because the output of lime shaft kiln is relatively small and the diameter of the cylinder of lime shaft kiln is relatively small, the fuel usage of lime shaft kiln with 200 tons per day is optional, such as anthracite and natural gas, so the fuel selection is different, so the technology of lime shaft kiln is not the same. Similarly, it is obvious that the calcination process of anthracite mixture is different from that of natural gas or gas, both in theory and in equipment itself.

Principle of 200 tons Lime Vertical Kiln

Like other lime shaft kiln principles, the final firing zone temperature is up to 1250 degrees Celsius by burning fuel in a closed kiln. However, the decomposition rate of calcium carbonate in limestone is the fastest at 1250 degrees Celsius, so the principle of 200 tons of lime shaft kiln per day is CaCO3 (s) = CaO (s) +CO2 (g), and the temperature condition is 1250 degrees Celsius.

Advantages of 200 tons Lime Vertical Kiln

The lime shaft kiln with a daily output of 200 tons has many advantages, among which small investment and low operating cost are the most important. Generally speaking, the total cost of the lime shaft kiln with a daily output of 200 tons is about 3.7 million. Of course, the specific situation needs specific analysis. Of course, there are some friends who want to collect heat. Now the lime market is very good. The construction speed of the lime shaft kiln with a daily output of 200 tons is very fast. So this has become a highlight of the lime shaft kiln. In sum, the lime shaft kiln with a daily output of 200 tons has many advantages.

Features

1.The kiln operation is flexible and can be adjusted arbitrarily from 60-100% to achieve stable production.
2.Applicable fuels are solid fuels such as coke and anthracite.
3.Low heat consumption, reasonable utilization of heat energy, secondary high temperature air preheated by cooling lime directly participates in combustion.
4.The shaft kiln adopts micro-negative pressure operation (kiln roof) to make the air flow in the kiln evenly distributed, which is conducive to the calcination of lime.
