Custom Lime Production Solutions with Vertical Shaft Kiln Design Options
Detailed Product Introduction
The vertical shaft lime kiln stands as a commanding and precisely engineered vertical structure, dedicated to advancing the art of lime burning. This state-of-the-art steel cylindrical masterpiece harnesses the sophisticated heat exchange mechanism, where the gravitational descent of raw materials synchronizes seamlessly with the upward movement of hot gases, resulting in lime of the highest quality and purity.stone. With meticulous management, materials are introduced from the top and extracted from the base post-calcination, with the kiln's strategic temperature gradient crafting 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 leverage the warmth of flue gases; within the calcination zone, they undergo calcination powered by heat from fuel combustion; in the cooling zone, the hot calcined materials transfer heat to the incoming cold air, effectively cooling themselves while providing heated air to sustain fuel combustion in the calcination zone. This holistic system ensures an uninterrupted and comprehensive calcination process. It integrates cutting-edge technology to optimize the use of cost-efficient energy sources, transforming environmentally degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into beneficial energy.
Highlighted Product Advantages
1) Unmatched Energy Efficiency: after the calcination process makes use of heat, the residual hot flue gas adeptly preheats incoming material, maximizing energy efficiency and remarkably reducing output flue gas temperature to an impressively low range of 170~300ºC.
2) The kiln's lining consists of four layers of robust refractory materials, delivering outstanding thermal insulation. The kiln shell maintains a temperature roughly 60°C above ambient, thereby minimizing excessive energy consumption.
3) Typically, the refractory materials boast a prolonged lifespan of 6 to 10 years, ensuring durability and long-term cost efficiency.
4) The kiln demonstrates exceptional fuel adaptability. It efficiently 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 options like coal gas and generator gas with considerable flexibility. Fuel oils such as heavy oil and diesel further enhance its versatility.
5) The strategic vertical shaft design, featuring a single bucket elevator and intelligently compact layout, optimizes space utilization.
6) Reduced investment requirements, our kiln offers an efficient streamlined steel structure with fewer machined parts, significantly cutting processing costs. The design simplifies installation, facilitating seamless construction of refractory materials, ensuring smooth operational execution.
