100-500 TPD Vertical Shaft Lime Kiln Production Line
Product Introduction
The innovative vertical shaft lime kiln stands as an exemplary piece of engineering excellence, tailored for lime burning. This streamlined and resilient equipment features an all-steel structure, leveraging the sophisticated heat exchange process between descending materials and ascending hot gases to meticulously burn limestone. With precision, materials are strategically added from the top and smoothly discharged from the bottom post-calcination. Delving into the kiln's core temperature dynamics, it is meticulously divided into three distinct zones: the preheat zone, calcination zone, and cooling zone.
In the initial preheat zone, materials utilize flue gas heat for preheating; advancing to the calcination zone, materials undergo calcination through potent fuel combustion heat; transitioning to the cooling zone, materials cool down as they exchange heat with incoming cold air, a process that also preps the air for subsequent combustion. Ensuring each calcination stage achieves full potential, these zones must maintain optimal heights and stability. Cutting-edge technology enables the kiln to harness inexpensive energy sources, remarkably repurposing environmentally harmful gases such as converter, blast furnace, and calcium carbide furnace tail gases into valuable energy.
Distinctive Product Advantages
1) Substantial Energy Savings: after combustion, residual heat from flue gas is ingeniously redirected to preheat materials to the ideal pre-decomposition temperature, significantly lowering the flue gas temperature down to an efficient 170~300ºC.
2) Superior Kiln Lining consists of four layers of high-quality refractory materials, providing exceptional thermal insulation. This design keeps the kiln shell temperature controlled at a mere 60°C above ambient levels, effectively cutting down on energy consumption.
3) Exceptional Durability, with refractory materials performing optimally for an impressive span of 6 to 10 years.
4) Versatile Fuel Compatibility, accommodating lump coal, coke, natural gas, coke oven gas, petroleum gas, and more. Innovative use of low calorific gases and liquid fuels like heavy oil further enhances efficiency.
5) Space Efficiency due to the vertical design of the shaft kiln and a large-angle single bucket elevator, optimizing functional area layouts to minimize footprint;
6) Reduced Operating Costs When it comes to investment, our kiln's innovative steel structure is engineered to minimize the number of machined parts, effectively lowering processing costs. This design not only ensures cost-efficiency but also simplifies the installation process. Building refractory materials becomes a seamless task, making it a preferred choice for industries aiming for excellence.
