Product description:
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.
Advantages:
1. 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%;
2.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, which is relatively low among all existing kiln types;
3. 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 , It is easy to take waste gas purification treatment measures, which is beneficial to reduce environmental pollution;
