Introducing the Cutting-Edge Vertical Shaft Lime Kiln Production Line: Your Premier 100-500 Tpd Solution
Comprehensive Product Overview
The vertical shaft lime kiln, a towering example of precision engineering, is dedicated to mastering the art of lime burning. This groundbreaking vertical cylindrical structure, crafted from advanced steel, employs an innovative heat exchange principle. As raw materials descend through gravity, they seamlessly interact with rising hot gases, resulting in lime of exceptional quality.stone. Carefully orchestrated, materials are introduced from the top and effortlessly retrieved from the bottom after calcination, with the kiln's precise temperature gradient defining three distinct operational zones. it features a meticulously planned division into the preheat zone, the critical calcination zone, and the efficient cooling zone..
In the preheat zone, materials absorb the warmth of flue gases; within the calcination zone, they undergo calcination through efficient heat generated by fuel combustion; in the cooling zone, the heated calcined materials transfer their heat to the incoming cold air, cooling themselves while effectively reheating air for combustion in the calcination zone. This integrated system guarantees a seamless and comprehensive calcination process. By integrating cutting-edge technology, it optimizes cost-effective energy use, transforming otherwise degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Highlighted Product Advantages
1) Unparalleled Energy Efficiency: after the calcination process, the residual hot flue gas is utilized to preheat 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 is composed of four layers of durable refractory materials, ensuring excellent thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thus minimizing unnecessary energy consumption.
3) Typically, the refractory materials boast an extensive lifespan of 6 to 10 years, providing durability and long-term cost-effectiveness.
4) The kiln demonstrates remarkable fuel adaptability. It skillfully manages mixed fuels like lump coal and coke, high-energy gases including natural gas and coke oven gas, plus alternative fuels like converter gas, blast furnace gas, and low-calorific fuels such as coal gas and generator gas with exceptional flexibility. Fuel oils such as heavy oil and diesel further amplify its versatility.
5) The innovative vertical shaft design, with its singular bucket elevator and intelligently compact configuration, optimizes space utilization.
6) Lowered investment needs, our kiln presents a streamlined, efficient steel structure with fewer machined components, substantially reducing processing costs. The design simplifies installation, facilitating seamless construction of refractory materials and ensures smooth operational execution.
