Unveiling the Vertical Shaft Lime Kiln Production Line: A Revolutionary 100-500 Tpd Solution
Detailed Product Introduction
The vertical shaft lime kiln stands as an imposing and meticulously engineered vertical structure, dedicated to the art of lime burning. This cutting-edge steel cylindrical design harnesses the pioneering heat exchange principle, where the gravitational descent of raw materials is perfectly counterbalanced by the ascent of hot gases, delivering lime of peerless quality.stone. With precision management, materials are introduced through the top and meticulously extracted from the base post-calcination, with the kiln's temperature gradient defining three distinct operational zones. it features a strategic division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials wisely make use of the warmth of flue gases; within the calcination zone, they undergo calcination through the intense heat generated by fuel combustion; in the cooling zone, the hot calcined materials efficiently transfer heat to the incoming cold air, cooling themselves while supplying heated air to fuel combustion in the calcination zone. This comprehensive system ensures an uninterrupted and complete calcination process, integrating advanced technology to optimize the use of economical energy sources, transforming environmentally degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Highlighted Product Advantages
1) Unmatched Energy Efficiency: after the calcination process uses heat, the residual hot flue gas efficiently preheats incoming material, maximizing energy efficiency and significantly reducing output flue gas temperature to a minimal 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, thereby minimizing excessive energy consumption.
3) Typically, the refractory materials demonstrate an extended lifespan of 6 to 10 years, ensuring durability and long-term cost efficiency.
4) The kiln boasts exceptional fuel adaptability. It manages mixed fuels like lump coal and coke, high calorific gases including natural gas and coke oven gas, and alternative fuels such as converter gas, blast furnace gas, and lower calorific fuels like coal gas and generator gas with remarkable flexibility. Fuel oils like heavy oil and diesel further enhance its versatility.
5) The strategic vertical shaft design, with its single bucket elevator and ingeniously compact layout, optimizes space utilization.
6) Reduced investment requirements, our kiln offers an efficient streamlined steel structure with fewer machined parts, significantly reducing processing costs. The design simplifies installation, facilitating seamless construction of refractory materials, ensuring smooth operational execution.
