Advanced Lime Kiln Solutions Vertical Shaft Kiln with 100-500 Tpd Capacity
In-depth Product Overview and Features
The vertical shaft li me kiln is a commanding, precision-engineered vertical masterpiece devoted to the art and science of lime burning. This pioneering steel cylindrical marvel employs cutting-edge heat exchange methodology, where the gravitational flow of raw materials is adeptly synchronized with the upward movement of hot gases, crafting lime of extraordinary quality.stone. With meticulous precision, materials are introduced at the zenith and removed from the nadir post-calcination, with the kiln's precise temperature gradient delineating three distinct operational realms. it boasts a meticulously crafted division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials harness the residual warmth of flue gases; within the calcination zone, they are calcined via the intense heat produced by fuel combustion; while in the cooling zone, the hot calcined materials efficiently transfer heat to the incoming cold air, achieving self-cooling while delivering preheated air for fuel combustion in the calcination zone. This all-encompassing system guarantees a flawless and thorough calcination process. It incorporates cutting-edge technology to optimize the utilization of economical energy sources, transforming environmentally challenging gases such as converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy resources.
Key Advantages of Our Product
1) Superior Energy Efficiency: after the calcination stage leverages heat, the residual hot flue gas efficiently preheats incoming materials, enhancing energy efficiency and dramatically reducing output flue gas temperature to a remarkably low range of 170~300ºC.
2) The kiln's lining consists of four robust layers of refractory materials, offering superior thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, significantly reducing unnecessary energy consumption.
3) Typically, the refractory materials have an extended lifespan of 6 to 10 years, ensuring lasting durability and cost-effectiveness.
4) The kiln exhibits outstanding fuel adaptability. It efficiently manages mixed fuels like lump coal and coke, high-calorific gases including natural gas and coke oven gas, alongside alternative fuels such as 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 enhance its versatility.
5) The intelligent vertical shaft design, featuring a single bucket elevator and strategically compact arrangement, maximizes space utilization.
6) Reduced investment needs, this kiln offers an efficient streamlined steel structure with fewer machined components, significantly lowering processing costs. Its design simplifies installation, facilitating seamless construction of refractory materials, ensuring smooth operational execution.
