Customized Vertical Shaft Lime Kiln for Magnesium Aluminum Lime Stone Metallurgical Industry
In-Depth Product Introduction
The vertical shaft lime kiln emerges as a towering and expertly crafted vertical masterpiece, specially designed for the intricate process of lime burning. This avant-garde steel cylindrical formation capitalizes on the sophisticated heat exchange principle, in which the natural gravitational movement of raw materials elegantly interacts with the rising hot gases, ensuring the production of lime of exceptional quality.stone. With precision management, materials are carefully introduced from the top and retrieved from the base post-calcination, while the kiln's temperature gradient orchestrates three distinct operational zones. it showcases a thoughtful division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials expertly utilize the heat of flue gases; within the calcination zone, they undergo calcination through the intense heat produced by fuel combustion; in the cooling zone, the hot calcined materials transfer heat to the incoming cold air, effectively cooling themselves while heating the air for combustion in the calcination zone. This intricate system ensures a seamless and thorough calcination process. It incorporates cutting-edge technology to optimize the use of economical energy sources, transforming environmentally harmful gases such as 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 efficiently uses heat, the remaining hot flue gas preheats incoming material, 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 robust refractory materials, providing outstanding thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thereby minimizing unnecessary energy consumption.
3) Generally, the refractory materials boast an extended lifespan of 6 to 10 years, ensuring durability and long-term cost-effectiveness.
4) The kiln presents remarkable 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, as well as lower calorific fuels like coal gas and generator gas with outstanding flexibility. Fuel oils such as heavy oil and diesel further enhance its versatility.
5) The clever vertical shaft design, coupled with its single bucket elevator and smartly compact layout, maximizes space efficiency.
6) Lowered investment needs, our kiln provides an efficient streamlined steel structure with fewer machined parts, significantly reducing processing costs. The design eases installation, promoting seamless construction of refractory materials and ensuring smooth operational execution.
