Detailed Product Introduction
The vertical shaft lime kiln stands as an imposing and meticulously engineered vertical structure, dedicated to the art of lime burning. This state-of-the-art steel cylindrical design leverages the advanced heat exchange principle, whereby the gravitational descent of raw materials harmonizes with the ascent of hot gases, to yield lime of unparalleled quality.stone. Meticulously managed, materials are fed through the top and extracted from the base post-calcination, with the kiln's temperature gradient creating three distinct operational zones. it features a strategic division into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials leverage the warmth of flue gases; within the calcination zone, they are calcined through the heat generated by fuel combustion; in the cooling zone, the hot calcined materials transfer heat to the incoming cold air, effectively cooling themselves while supplying heated air to fuel combustion in the calcination zone. This comprehensive system ensures a seamless and complete calcination process. Integrates leading-edge technology to optimize the use of cost-effective energy sources, turning environmentally degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Highlighted Product Advantages
1) Unmatched Energy Efficiency: after the calcination process utilizes heat, the leftover hot flue gas effectively preheats incoming material, maximizing energy efficiency and substantially lowering output flue gas temperature to a minimal range of 170~300ºC.
2) The kiln's lining comprises four layers of resilient refractory materials, providing excellent thermal insulation. The kiln shell retains a temperature roughly 60°C above ambient, thereby minimizing excessive energy consumption.
3) Typically, the refractory materials exhibit a prolonged lifespan of 6 to 10 years, ensuring durability and long-term cost efficiency.
4) The kiln showcases exceptional fuel adaptability. It handles mixed fuels like lump coal and coke, high calorific gases including natural gas and coke oven gas, and alternative fuels such as converter gas, blast furnace gas, and lesser calorific fuels like coal gas and generator gas with impressive flexibility. Fuel oils such as heavy oil and diesel further enhance its versatility.
5) The strategic vertical shaft design, with its single bucket elevator and intelligently compact layout, maximizes space utilization.
6) Reduced investment requirements, our kiln offers an efficient streamlined steel structure with fewer machined parts, significantly cutting processing costs. The design simplifies installation, facilitating seamless construction of refractory materials, ensuring smooth operational execution.
