Reliable Vertical Shaft Lime Kiln Supplier for Large Capacity Needs
Product Introduction
The vertical shaft lime kiln stands as a towering masterpiece of precision engineering, meticulously designed for the efficient and flawless burning of lime. This cutting-edge kiln boasts a robust all-steel cylindrical structure that masterfully harnesses the power of heat exchange. It orchestrates a seamless interaction between the gravitational descent of raw materials and the ascent of hot gases, producing lime of unmatched quality.stone. Materials are methodically introduced at the summit and collected from the base following calcination. The internal temperature gradient brilliantly segregates the kiln into three distinct and essential zones. it is divided into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are gently introduced to the comforting warmth of flue gas; in the calcination zone, they undergo meticulous calcination through the heat generated by fuel combustion; and in the cooling zone, the freshly calcined materials transfer their heat to incoming cool air, efficiently cooling themselves while providing preheated air to fuel the calcination zone. This sophisticated system ensures each phase of the calcination process is executed with seamless precision and thoroughness. Incorporating cutting-edge technology, it optimizes the use of economical energy sources, including environmentally challenging gases like 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 reducing output flue gas temperature to an impressive range of 170~300ºC.
2) The kiln lining consists of four layers of resilient refractory materials, providing exceptional thermal insulation. The kiln shell maintains a temperature just 60°C above ambient, dramatically reducing excessive energy consumption.
3) Typically, the refractory materials enjoy an extended lifespan of 6 to 10 years, ensuring longevity and cost-efficiency.
4) Displaying remarkable fuel adaptability, the kiln operates seamlessly with various fuels. From mixed fuels like lump coal and coke, to high-calorific gases like natural gas and coke oven gas, and alternative fuels such as 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.
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.
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 operational setup.
