100 Ton Per Day Lime Kiln Manufacturers in China
In the field of lime production, the manufacturing of a 100 ton daily lime kiln requires a balance between efficiency, energy consumption, and environmental protection, which poses a severe test on the manufacturer's ability to integrate technology. Top Chinese enterprises have achieved breakthrough upgrades in equipment performance through structural innovation and process optimization.
In terms of kiln design, mainstream manufacturers adopt a straight cylindrical structure, with a kiln diameter controlled between 6.5 meters and 7.6 meters and a height of 31 meters to 39 meters. This proportional design not only ensures the uniformity of material heating, but also reduces heat loss by optimizing the heat dissipation area of the kiln body. The refractory material is made of high alumina phosphate brick or composite carbon steel, combined with nano aerogel felt insulation layer, so that the surface temperature of the kiln body is 40% lower than that of traditional equipment, and the thermal efficiency is increased to more than 85%.
The combustion system is the core breakthrough point. Manufacturers generally use dual channel burners, which control the flame shape by adjusting the ratio of internal/external air, and cooperate with PLC automation control systems to achieve precise temperature field regulation. In terms of fuel adaptation, it supports multi fuel switching of coal, natural gas and converter gas. The gas pulverized coal composite combustion technology can reduce the fuel cost by 25%, while the oxygen content can be increased to 25% through oxygen enriched combustion technology, and the combustion efficiency can be increased by 15%.
In terms of environmental performance, the manufacturer integrates a five stage suspension preheater and grate cooler, reducing the exhaust gas temperature to below 250 ℃ and the secondary air temperature to 800-900 ℃, achieving a waste heat recovery rate of over 60%. The exhaust gas treatment adopts three-level purification of "cyclone dust removal+pulse bag+wet electrostatic precipitator", combined with limestone gypsum wet desulfurization and SNCR denitrification technology, to achieve particle emissions ≤ 5mg/m ³, SO ₂ emissions ≤ 20mg/m ³, NOx emissions ≤ 100mg/m ³, far below the national industrial kiln emission standards.
