Premium Limestone Calcination Rotary Kiln for Global Markets
Comprehensive Product Overview
The vertical shaft lime kiln is a commanding and expertly crafted vertical marvel, devoted to the sophisticated lime burning process. This modern steel cylindrical masterpiece utilizes advanced heat exchange principles, where raw materials descend by gravity while hot gases rise, producing lime of exceptional quality.stone. With precision, materials are meticulously fed from the top and retrieved from the bottom after calcination, as the kiln's temperature gradient establishes three distinct operational zones. it boasts a meticulous division into the preheat, calcination, and cooling zones..
In the preheat zone, materials utilize the heat of flue gases; in the calcination zone, they undergo calcination via the heat from fuel combustion; in the cooling zone, the hot calcined materials transfer heat to incoming cold air, cooling themselves while providing heated air for combustion in the calcination zone. This sophisticated system guarantees an uninterrupted and comprehensive calcination process. It incorporates cutting-edge technology to maximize the use of cost-efficient energy sources, transforming environmentally harmful gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy resources.
Key Product Benefits
1) Superior Energy Efficiency: after utilizing heat in the calcination process, remaining hot flue gas effectively preheats incoming materials, optimizing energy efficiency and significantly reducing output flue gas temperature to an impressive range of 170~300ºC.
2) The kiln's lining is composed of four layers of robust refractory materials, ensuring exceptional thermal insulation. The kiln shell maintains a temperature approximately 60°C above ambient, thereby reducing unnecessary energy consumption.
3) Generally, the refractory materials have a durable lifespan of 6 to 10 years, ensuring resilience and long-term economic efficiency.
4) The kiln exhibits remarkable fuel flexibility. It accommodates mixed fuels such as lump coal and coke, high-calorific gases like natural and coke oven gases, as well as alternative fuels like converter gas, blast furnace gas, and lower calorific options such as coal and generator gas with outstanding adaptability. The use of fuel oils like heavy oil and diesel further broadens its versatility.
5) The strategic vertical shaft design, featuring a single bucket elevator and smartly compact layout, optimizes space efficiency.
6) Reduced investment costs, our kiln provides an efficient, streamlined steel structure with fewer machined components, substantially reducing processing expenses. The design simplifies installation, ensuring seamless construction of refractory materials and smooth operational execution.
