Double-Chamber Shaft Kiln Introduction:
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.
Other Name: Maerz Kiln:
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.
Our Advantages of Double-Chamber Shaft Kiln:
1. High heat utilization rate: Due to the heat storage heat exchange system, high-temperature exhaust gas is discharged through the preheated kiln, and after a long time of heat exchange, the heat is transferred to the material, and the waste heat is fully utilized, thus achieving the purpose of energy saving . The heat consumption per unit product can reach 850kcal/kg, double-chamber shaft kiln is relatively low among all existing kiln types;
2. The exhaust gas temperature and dust content are low: the exhaust gas temperature is very low due to the sufficient heat exchange between the exhaust gas and the material, the exhaust gas temperature is 90-130°C under normal conditions, and the dust concentration in the exhaust gas is generally 5-8g/m³ , double-chamber shaft kiln is easy to take waste gas purification treatment measures, which is beneficial to reduce environmental pollution;
3. 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;

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.
