    600tpd Energy Saving Double-Chamber Shaft Kiln / Maerz Kiln


    Double-Chamber Shaft Kiln Other Name:

    Maerz Kiln

    Capacity: 50-800(t/d)
    Limestone size: 30~60/40~80(mm)
    Scope: Suitable for industries such as metallurgy, building materials, calcium carbide, aerated concrete and sugar.
    The double-chamber heat storage shaft kiln is commonly called Maerz kiln. Compared with other lime kilns, it has the lowest heat consumption, high activity of calcined lime and low residual carbon dioxide.


    Working Principle of Double-Chamber Shaft Kiln:

    The double-chamber lime ash shaft kiln has two kiln chambers, and the two kiln chambers are connected by a connecting passage through which gas can flow from one kiln chamber to another. The two kiln chambers alternately calcine and preheat the stone, and the working status of the kiln chamber is changed every 12-15 minutes.


    Process Characteristics of Double-Chamber Shaft Kiln:

    The stone is loaded from the top of the kiln, and the fuel is fed into the upper part of the double chamber shaft kiln. The spray guns located at the bottom of the pre-tropical zone are evenly distributed across the section of the double chamber shaft kiln. The combustion-supporting air is fed from the upper part of the double chamber shaft kiln. The combustion-supporting air is preheated in the preheating zone before mixing with the fuel, and then the calcining flame gas flows through the calcining zone and flows co-currently with the ore to obtain the ore. The calcined waste gas is discharged to the top of the kiln along the preheating belt of the other kiln through the passage connecting the two kilns. Due to the long process of parallel calcination, the lime quality is very good, and due to the alternate operation of the two kilns, the waste gas directly preheats the ore, and the heat is fully utilized, so the unit heat consumption is lower in various kilns.

    Our Advantages of Double-Chamber Shaft Kiln:

    1. Convenient quality inspection: There are 2×8 quality inspection doors under the double-chamber shaft kiln, and the fuel supply of the corresponding burner can be adjusted to ensure the quality by checking the product quality of each part;
    2. Reliable equipment: Most of the equipment on the double-chamber shaft kiln adopts hydraulic operation, and the operation is stable and reliable. These equipments include: air and exhaust gas reversing gate, chimney exhaust gas reversing gate, kiln closing gate, feeding hopper gate, discharge device, discharge hopper sealing gate and material level indicator, etc.;
    3. The double-chamber shaft kiln body has good heat insulation performance: the surface temperature is low, which not only protects the environment but also saves energy.

    4. Parallel calcination: This is the technical feature of the double-chamber shaft kiln. Because the high temperature flame contacts the lower temperature material, the heat exchange rate is very high, and the relatively low temperature hot gas contacts the material to be burned. Avoiding over-firing and under-firing, the roasted product has better quality, higher activity, up to 360ml or more, and less residual CO2, generally not higher than 2.5%;
