Activated Lime Gypsum Bauxite Metallurgy Rotary Vertical Lime Kiln
Comprehensive Overview of Product Features
The vertical shaft lime kiln emerges as a formidable and intricately designed vertical marvel, devoted to the sophisticated art of lime burning. This cutting-edge steel cylindrical architecture employs the eminent heat exchange principle, where the descent of raw materials in perfect harmony with the ascent of hot gases produces lime of extraordinary purity and consistency.stone. With meticulous precision, materials are introduced from the apex and retrieved from the base post-calcination, facilitated by a temperature gradient within the kiln that cultivates three specialized operational zones. It boasts a methodical segmentation into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials embrace the warmth of flue gases; in the calcination zone, they undergo calcination driven by the heat emerging from fuel combustion; in the cooling zone, the hot calcined materials transfer heat to incoming cold air, cooling themselves while providing heated air to fuel combustion in the calcination zone, ensuring a seamless and exhaustive calcination process. This advanced system incorporates cutting-edge technology to harness cost-effective energy sources, transforming environmentally degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy, exemplifying eco-friendly innovation.
Key Advantages of the Product
1) Superior Energy Efficiency: After the calcination phase, the residual hot flue gas proficiently preheats incoming materials, maximizing energy efficiency and notably reducing exhaust flue gas temperature to an impressively low range of 170~300ºC.
2) The kiln's lining consists of four layers of robust refractory materials, ensuring exceptional thermal insulation. The kiln shell maintains a temperature about 60°C above ambient, thus minimizing unnecessary energy usage.
3) Typically, the refractory materials demonstrate an extended lifespan of 6 to 10 years, promising durability and long-term cost-effectiveness.
4) The kiln exhibits exceptional adaptability to a variety of fuels, accommodating mixed fuels like lump coal and coke, high calorific gases such as natural gas and coke oven gas, and alternative fuels like converter gas, blast furnace gas, and low calorific fuels like coal gas and generator gas with remarkable flexibility. Fuel oils, including heavy oil and diesel, further augment its versatility.
5) The strategic vertical shaft design, along with a single bucket elevator and intelligently compact layout, maximizes spatial efficiency.
6) Lowered investment requirements, our kiln provides an efficient streamlined steel structure with fewer machined components, significantly reducing processing costs. The design simplifies installation, enabling seamless construction of refractory materials, ensuring smooth operational execution.
