Efficient Lime Kiln Solutions: Customized Vertical Shaft Kiln for 100-500 Tpd
In-Depth Product Introduction
The vertical shaft lime kiln stands as a monumental and precisely crafted vertical structure, designed for the sophisticated process of lime burning. This cutting-edge steel cylindrical formation utilizes the progressive heat exchange principle, where the harmonious gravitational flow of raw materials meets the upward journey of hot gases, resulting in lime of exceptional purity.stone. With meticulous precision, materials are introduced from above and extracted from the base post-calcination, as the kiln's temperature gradient orchestrates three distinct operational zones. it features an intelligent division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials efficiently capture the warmth of flue gases; within the calcination zone, they undergo calcination through the heat produced by fuel combustion; in the cooling zone, the hot calcined materials impart heat to the incoming cold air, cooling themselves while providing heated air for combustion in the calcination zone. This integrated system guarantees a smooth and complete calcination process. It incorporates state-of-the-art technology to enhance energy efficiency, transforming environmentally harmful gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy resources.
Highlighted Product Advantages
1) Exceptional Energy Efficiency: After the calcination process makes use of heat, the residual hot flue gas effectively preheats incoming materials, optimizing 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, offering superior thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thereby minimizing excessive energy consumption.
3) Typically, the refractory materials boast an extended lifespan of 6 to 10 years, ensuring durability and long-term cost efficiency.
4) The kiln demonstrates remarkable fuel adaptability. It efficiently processes mixed fuels like lump coal and coke, high calorific gases such as natural gas and coke oven gas, and alternative fuels including converter gas, blast furnace gas, and lower calorific fuels like coal gas and generator gas with extraordinary flexibility. Fuel oils such as heavy oil and diesel further enhance its versatility.
5) The strategic vertical shaft design, complemented by its single bucket elevator and intelligently compact layout, fully optimizes space utilization.
6) Reduced investment requirements, our kiln features an efficient and streamlined steel structure with fewer machined components, significantly reducing processing expenses. The design simplifies installation, ensuring smooth construction of refractory materials, for effortless operational execution.
