System technology for the use ofscrap tires and other alternative fuels for kiln firing in the cement industry >

BEUMER systems for burning scrab tires - 4

BEUMER has developed a specialtechnology for the utilization of al- ternative fuels in the high tempera- ture process of rotary kilns which has proven its viability in a large number of installations supplied to the cement industry. Due to the continuous improvement of this technology using the important ex- perience gained a standard of high quality and reliability could beachieved. The enclosed flow sheet illustrates clearly the way of the combustibles from their delivery up to the kiln inlet. >

Because of the increase in moto- rization, more and more tires are dumped at landfill. Due to the large material quantities needed their outer nature and the unit weight which can amount to a maxium of 80 kg, the energetic utilization of scrap tires as an alternative fuel requires an automatic handling system. The manual handling of this task has to be excluded, the dumping of the tires in the storage area as well as all further handling processes are preferably done by means of bucket-wheel reclaimers and gantry cranes with polygon grippers. The size of the storage area should correspond...

Scrap tires from delivery to the burning process > The machine technology The handling of scrap tires requiresa special know how as well as a particular technology.The difficulty is to grant a secure,controlled and automatic operation independent of the condition of the tires as well as the weather condi- tions. This is highly important due to the fact that the kiln process and consequently the quality of the cement clinker are influenced by the supply of fuel. With regard to their constructionand function the single machine components must be suitable for the scrap tires of random size and...

The design of the kiln inlet valveand its functional shape essentially depend on the type of fuel to be fed. Whole tires require a specifi- cally different supply than for example shredded materials, the throughput capacity and the related calorific value determine the ope- ning intervals which are realized by the process control of the kiln. The valve system consists of three steps connected in series which can be designed as flat slide val- ves or swivel valves. The upper and central step open and close in forced order to protect the kiln operation against heat loss and leakage of air....
