Cimprogetti has selected an innovative SCR process for Parallel Flow Regenerative (PFR) kilns with the specific aim of reducing NOx content in flue gases.Placed downstream of the kiln, the TurNOx device modulates parameters without affecting the calcination process in the kiln.The TurNOx device complies with the main directives regulating emissions into the atmosphere, in particular, the Best Available Techniques.

The ABC kiln features a cylindrical steel shell and is internally lined with standard-size refractory bricks. The limestone is continuously fed into the sealed loading/distributing device placed on the top of the kiln. Burning takes place in the lower/middle part of the kiln, through a number of burners distributed in several rows around the kiln shell to ensure homogeneous and consistent distribution of the heat over the entire kiln cross section. The lower section of the kiln is equipped with a lime discharge and a lime cooling section by means of air which is introduced from the bottom of the discharge table.

Low Power Consumption Vertical Shaft Kiln Active Lime Production Line Process Flow of Lime Production Line: 1. Raw Material Conveying: The 20-40mm limestone on the stock ground is sent to storage silo by the B1000 belt conveyor with large inclination. In the storage silo, qualified limestone with granularity more than 10mm will be sent to the gravel silo, while limestone with particle size less than 10mm will be conveyed to the powder silo. 2. Limestone Calcining: The limestone calcining system is mainly made up of 10.58.5m vertical preheater, 4.060m rotary kiln and vertical coolder whose output is 600t/d and heat consumption of 5.75GJ/t. Limestone inside the preheater is heated by high-temperature gases from rotary kiln to 600-800C, at which temperature limestone can be partly decomposed. Then the limestone will be sent by 12 hydraulic push rods to the kiln end, where it will undergo high-temperature calcination before sent to the vertical cooler. The processed limestone will be cooled down by cold air to 65C. Air from the vertical cooler enters into the rotary kiln as the second air to take part in calcining process. 3. Finished Product Conveying: The final lime will be sent to the storage bin for final products by NE500 bucket elevator. After screening, qualified lime whose particle size is more than 5mm will be sent to storage for active lime, while powder lime whose size is less than 5mm will be sent to storage bin for powder. 4. Gas Treating: High-temperature gases from rotary kiln will do heat exchange with limestone inside the preheater, and after that, the temperature of these gases will reduce to lower 280C. Then these gases will be cooled down by multi-tube cooler to 200C lower. Finally, they enter into the bag filer before discharged into the atmosphere. Mixed Burning Vertical Lime Kiln Process The qualified raw materials and solid fuels are mixed uniformly according to a certain proportion and then sent to the vertical kiln through a single bucket elevator for calcination. After calcination, the final lime products are discharged from the bottom of the vertical kiln through a discharge device to the conveyor, and the conveyor sends the final lime products to the storage silo. The hot flue gas generated by calcination will firstly go into the dust collecting system, and then the clean flue gas will be emitted through chimney to the atmosphere.

Along with rotary lime kiln, vertical lime kiln technology is vital for quicklime production plant. And compared with lime rotary kiln technology, vertical lime kiln technology is simple in construction and design. It used to think that vertical lime kiln can not burn the limestone inside more thoroughly than rotary lime kiln. However, Daswell vertical lime kiln technology has underwent constant technological innovations and is kept up with technology development. As a result, Daswell vertical shaft lime kiln can produce high quality burnt lime with high uniformity and consistency. In all, Daswell vertical lime kiln is cost effective, durable and reliable equipment for lime calcination plant with low energy consumption. And it is the suitable solution for lime production plant with low capacity requirements. Vertical Lime Kiln Manufacturer Vertical Shaft Lime Kiln Technology Get Solutions Name:* Email:* Phone Message:* Vertical Kiln for Lime Plant Design Unlike rotary lime kiln, vertical lime kiln is a static steel vessel for the calcination of limestone to produce quicklime. And inside the vertical shaft kiln for lime, there are several insulating layers, the permanent lining and wear lining. These refractory materials in the vertical lime kiln can protect the vertical lime kiln shell from damaging for high temperature, and decrease thermal diffusion to save energy. And the vertical lime kiln can be divided into three zones: preheating, calcining and cooling zones. By going through these three zones one by one, the limestone will be thoroughly burnt to produce quicklime while the carbon dioxide will drive off the kiln by air blowers. The sizes of Daswell vertical lime kiln are variable and can be customized according to customersneeds in production capacity and so on. Vertical Lime Kiln Process The manufacturing process of quicklime plant with vertical lime kiln includes crushing, calcining and delivering and packing. First the quarried limestone is crushed to small sizes and be washed and sifted for use. Here are the exact vertical kiln process or operation. The limestone of required sizes is fed from the top of the vertical lime kiln, from where it will move downward through the vertical lime kiln by gravity. That is, the limestone will go through the preheating, calcining and cooling zones in the kiln. And the fuel is introduced from the bottom of the vertical lime kiln. Then the decomposition of limestone takes place in the vertical lime kiln, whereby limestone is split into quicklime and carbon dioxide which will be driven off the kiln through vent devices. Finally, the quicklime will be transported to the product silo. Of course, there are also dust collectors and other devices. Please fill the form below to get free quotes. We will reply in 24 hours.
