Introducing the 100-500 Tpd Vertical Shaft Lime Kiln Production Line
Product Introduction
The vertical shaft lime kiln is a sophisticated, towering vertical instrument meticulously engineered for the precision burning of lime. Boasting an ingeniously designed all-steel cylindrical framework, it harnesses the groundbreaking principle of heat exchange. This process artfully orchestrates the graceful descent of materials under gravity with the upward surge of hot gases, culminating in the production of lime of unparalleled quality.stone. Materials are introduced with precision at the summit and are expertly retrieved from the base post-calcination. The kiln's temperature gradient is meticulously divided into three distinctive zones. it is segmented into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are gently warmed by the flue gas; in the calcination zone, they undergo a transformative calcination through the expertly generated heat from fuel combustion; and in the cooling zone, the hot calcined materials efficiently release heat to the incoming cold air, simultaneously cooling down while optimally heating air to fuel the combustion in the calcination zone. This state-of-the-art system guarantees a seamless and comprehensive execution of every phase in the calcination process. Leveraging pioneering technology, it maximizes cost-efficient energy sources, turning otherwise environmentally detrimental gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy resources.
Product Advantages
1) Energy Efficiency: after the combustion and subsequent heat release for calcination, the remaining hot flue gas effectively preheats incoming material, optimizing energy consumption and significantly reducing output flue gas temperature to an impressively lower range of 170~300ºC.
2) The kiln lining is composed of four formidable layers of refractory materials, providing extraordinary thermal insulation. The kiln shell sustains a temperature approximately 60°C above ambient levels, effectively mitigating excessive energy usage.
3) Typically, these resilient refractory materials boast an impressive lifespan ranging between 6 to 10 years, ensuring long-term durability and cost-effectiveness.
4) The kiln's extraordinary fuel adaptability is evident. Whether utilizing mixed fuels such as lump coal and coke, high-calorific gases like natural gas and coke oven gas, or alternative fuels such as converter gas, blast furnace gas, along with low-caloric sources like coal gas and generator gas, the kiln performs with unparalleled flexibility. Additionally, the inclusion of fuel oil options such as heavy oil and diesel further exemplifies its extensive versatility.
5) The vertical shaft design, combined with the precisely angled single bucket elevator and the intelligently compacted layout, ensures optimal space utilization.
6) Lower When considering investment, our kiln features an elegant and streamlined steel structure with a reduced number of machined parts, leading to remarkably lower processing costs. The design not only simplifies installation but also facilitates the construction of refractory materials with ease, ensuring a seamless and efficient operational setup.
