High-Quality Lime Kiln Solutions for Large Scale Production
A Thoroughly Detailed Product Introduction
The vertical shaft lime kiln emerges as a towering and meticulously constructed vertical marvel, dedicated to the art of lime production. This cutting-edge steel cylindrical design employs the advanced heat exchange principle, where the gravitational descent of raw materials beautifully synchronizes with the upward rise of hot gases, producing lime of unmatched quality.stone. With precision management, materials are strategically introduced from the top and extracted from the base post-calcination, while the kiln's temperature gradients create 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 warmth of flue gases; within the calcination zone, they are calcined through the intense heat generated by fuel combustion; in the cooling zone, the hot calcined materials transfer their heat to the incoming cold air, effectively cooling themselves while supplying preheated air to fuel combustion in the calcination zone. This comprehensive system ensures a seamless and complete calcination process. It integrates state-of-the-art technology to optimize the use of economical energy sources, transforming environmentally harmful gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Outstanding Product Benefits Highlighted
1) Unparalleled Energy Efficiency: after the calcination process utilizes heat, the residual hot flue gas effectively preheats incoming materials, maximizing energy efficiency and significantly reducing output flue gas temperature to an impressively low range of 170~300ºC.
2) The kiln's lining features four layers of durable refractory materials, offering exceptional thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thereby minimizing unnecessary energy waste.
3) Typically, the refractory materials exhibit a robust lifespan of 6 to 10 years, ensuring durability and long-term cost effectiveness.
4) The kiln demonstrates exceptional fuel adaptability. It efficiently handles 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 impressive flexibility. Fuel oils such as heavy oil and diesel further enhance its versatility.
5) The intelligently designed vertical shaft, equipped with a single bucket elevator and a compact layout, optimizes space utilization.
6) Reduced investment requirements, our kiln offers an efficient streamlined steel structure with fewer machined parts, significantly lowering processing expenses. The design simplifies installation, enabling seamless construction of refractory materials and ensuring smooth operational performance.
