Introducing the Next Generation Vertical Shaft Lime Kiln Production Line: A Game-Changing 100-500 Tpd Solution
In-Depth Product Overview
The vertical shaft lime kiln is a towering testament of meticulous engineering, dedicated to the sophisticated art of lime burning. This cutting-edge steel cylindrical structure employs an advanced heat exchange principle, wherein the natural gravitational descent of raw materials perfectly synchronizes with the upward motion of hot gases, yielding lime of exceptional quality.stone. With precision management, materials are skillfully introduced from the top and retrieved from the bottom post-calcination, as the kiln's temperature gradient establishes three distinct operational zones. It boasts a strategic division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials harness the thermal energy of flue gases; within the calcination zone, they undergo calcination by the heat generated from fuel combustion; in the cooling zone, the hot calcined materials transfer heat to the incoming cold air, efficiently cooling themselves while supplying preheated air for combustion in the calcination zone. This well-orchestrated system guarantees a smooth and comprehensive calcination process. It integrates cutting-edge technology to enhance the utilization of cost-effective energy sources, transforming environmentally degrading gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Key Product Advantages
1) Superior Energy Efficiency: After the calcination process capitalizes on the heat, the remaining hot flue gas efficiently preheats incoming material, optimizing energy efficiency and significantly reducing output flue gas temperature to an impressively low range of 170~300ºC.
2) The kiln's lining is composed of four layers of robust refractory materials, delivering excellent thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, effectively minimizing unnecessary energy usage.
3) Typically, the refractory materials demonstrate a sustained lifespan of 6 to 10 years, ensuring durability and long-term economic efficiency.
4) The kiln exhibits remarkable fuel adaptability. It accommodates mixed fuels like lump coal and coke, high calorific gases such as natural gas and coke oven gas, and alternative fuels including converter gas, blast furnace gas, and lower calorific fuels like coal gas and generator gas with remarkable flexibility. Fuel oils such as heavy oil and diesel further extend its versatility.
5) The intelligent vertical shaft design, featuring a single bucket elevator and a thoughtfully compact layout, maximizes spatial efficiency.
6) Lowered investment needs, our kiln offers an efficient streamlined steel structure with fewer machined parts, significantly reducing processing costs. The design simplifies installation, ensuring seamless construction of refractory materials and guaranteeing smooth operational performance.
