    50tpd Nature Gas Lime Plant , Quicklime Vertical Shaft Kiln Plant Plc Control

    50tpd nature gas lime Plant Quicklime Shaft Vertical Kiln plant


    Introduction:

    Lime vertical shaft kiln has many forms, the vertical kiln with continuous operation is mostly adopted. Its heating fuel includes coal, nature gas and coal gas. The solid fuel can be added together with the limestone, it can also be burned into gas outside the kiln and then introduced into it. The former is called mixing shaft kiln, the latter is called gas kiln. Mixing shaft kiln has the advantages of large production capacity, fully mechanized procedure, high concentration of kiln gas, high thermal efficiency, good lime quality and so on, so it is often adopted.
    Structure of lime kiln equipment is shown below. The kiln shell is formed of ordinary brick or steel plate, its inner is formed of refractory bricks, the thermal insulation material (e.g., asbestos slag, foam diatomite, etc.) is filled between the two layers to reduce heat loss. Air is blowed into the kiln by blower below.


    Working Principle:

    After mixed well, blocks of limestone and coke are put into the kiln above. They do top-down movement and go through three areas: preheating zone, calcining and cooling zone. Preheating zone is located in the upper part of kiln, accounting for 1/4 of the total height, and it uses the hot kiln gas from the calcining zone to preheat and dry the limestone fuel and evaporate the moisture. When the temperature exceeds 70 degrees, furnace burden starts to burn. Hot kiln gas conducts nearly half heat to furnace burden, and its temperature drops to 50-100 degrees, discharged from the kiln crown. Calcining zone is located in the middle of the kiln, accounting for 1/2 of the kiln height. To avoid over-sintering, this zone temperature should not exceed 1200 degrees. Cooling zone is located in the bottom of the kiln, about 1/4 of the total kiln height, its main role is to preheat the air in the kiln to cool the hot lime to 30-60 degrees, not only recycle the heat but also protect the kiln gate from burning-out.
    The main technological conditions to maintain the normal operation of lime kiln is to maintain the normal and stable temerature distribution inside the kiln.


    Our Advantages:


    The vertical kiln was manufactured by YUHONG Corp with modern new technology, which is an environment protection, save energy, higher machanization and automaticity, quite modern lime kiln. Because it adopts the modern technology, make full use the cheap energy, especially pollution of gas for environment harmful( such as conventer gas, blast furnace gas, calcium carbide furnace tail gas) as the energy, turn waste into wealth. Thus will protect the environment, and produce the high quality lime with lowest cost. To use this new technology enterprise, economic benefits have increased significantly.
