Large Capacity Shaft Lime Kiln for High-Efficiency Production Systems
Product Introduction
The vertical shaft lime kiln stands as a towering masterpiece of precision engineering, meticulously designed for the efficient and precise burning of lime. This innovative kiln boasts a robust all-steel cylindrical structure that harnesses the transformative power of heat exchange. It brilliantly orchestrates the interaction between the gravitational descent of raw materials and the ascent of hot gases. The result is lime of unparalleled quality, a testament to advanced engineering.stone. Materials are meticulously introduced at the summit and harvested from the base following calcination. The internal temperature gradient ingeniously segregates the kiln into three distinct and essential zones, ensuring optimal processing at every step. it is divided into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are gently coaxed by the comforting warmth of flue gas; in the calcination zone, they are meticulously calcined through the precision heating generated by fuel combustion. In the cooling zone, the freshly calcined materials impart their heat to incoming cool air, effectively cooling themselves while simultaneously providing preheated air to fuel the calcination zone. This sophisticated system ensures each phase of the calcination process is executed with seamless precision and completeness. Incorporating groundbreaking technology, it optimizes the use of economical energy sources, including environmentally-challenging gases such as converter gas, blast furnace gas, and calcium carbide furnace tail gas, transforming potential waste into valuable energy assets.
Product Advantages
1) Energy Efficiency: after combustion, the remaining hot flue gas ingeniously preheats incoming materials, maximizing energy efficiency and significantly reducing output flue gas temperature to an impressive range of 170~300ºC.
2) The kiln lining is composed of four layers of resilient refractory materials, providing exceptional thermal insulation. The kiln shell maintains a temperature just 60°C above ambient, dramatically minimizing excessive energy consumption.
3) Typically, the refractory materials enjoy an extended life span of 6 to 10 years, ensuring longevity and cost-efficiency while significantly reducing maintenance interruptions.
4) Displaying remarkable fuel adaptability, the kiln operates seamlessly with various fuels. From mixed fuels like lump coal and coke, to high-calorific gases such as natural gas and coke oven gas, and alternative fuels including converter gas, blast furnace gas, and low calorific fuels like coal gas and generator gas, it showcases unrivaled flexibility. Additionally, fuel oil options like heavy oil and diesel further enhance its versatility, catering to a wide range of operational needs.
5) Thanks to its vertical shaft design, the strategic angle of the single bucket elevator, and an intelligently compact layout, space is utilized to its maximum potential, offering a plant configuration that is both efficient and space-saving.
6) Lower investment costs are a highlight of our kiln, characterized by a streamlined steel structure with fewer machined parts, significantly reducing processing expenses. Its design simplifies installation and supports the construction of refractory materials effortlessly, ensuring a seamless and rapid operational setup.
