100tpd Shaft Lime Kiln for quick Lime
The 100TPD shaft lime kiln is a highly efficient vertical kiln designed for producing high-quality quicklime (calcium oxide, CaO) from limestone (calcium carbonate, CaCO₃). This kiln is widely used in steelmaking, chemical industries, water treatment, and construction due to its stable performance, energy efficiency, and environmental compliance. Below are the key technical parameters and features of this kiln.
Key Technical Parameters
Production Capacity: 100 tons per day (adjustable based on limestone quality)
Fuel Type: Coal, natural gas, biomass, or mixed combustion
Coal Consumption: ~120 kg per ton of quicklime (depending on limestone quality)
Quicklime Activity: ≥280 mL (high reactivity for industrial applications)
Calcination Temperature: 900-1150°C (optimized for complete decomposition)
Limestone Size Requirement: 40-80 mm (uniform size for efficient calcination)
Quicklime Purity: ≥90% CaO (low residual CO₂ content)
Thermal Efficiency: ≥75% (superior heat utilization compared to traditional kilns)
Dust Emission: ≤30 mg/Nm³ (meets national environmental standards)
NOx & SO₂ Emissions: Compliant with China’s GB 13271-2014 standards
Design Features & Advantages
Vertical Shaft Structure – The compact design ensures uniform heat distribution, reducing energy waste and improving calcination efficiency.
Advanced Heat Recovery System – Preheats incoming limestone using exhaust gases, lowering fuel consumption.
