BEUMER System Technology for the Use of Scrap Tires - 2

Energetic utilization of scrap tires and other waste solid fuels The required energy input causes about 40% of the production costs for the manufacture of cement. Therefore apart from standard combustibles like coal, fuel oil and gas the so called alternative fuels are of considerable interest, besides a useful waste disposal their utilization offers important economical advantages.

Next to waste oil, scrap tires, shredded tires, well as shredded wood, synthetic materials,and oil saturated mineral substances are suitable waste or secondary fuels. Possible alternative fuels are available in large quantities and at a favorable price. They can be disposed in the high temperature process of the rotary kiln systems of cement plants without any risk. There is neither a danger of inadmissible environmental pollution like toxic emissions nor a reduction of the quality of the cement. During the high temperature process all contaminants are completely destroyed at a material...

Alternative fuels for energy suppliers as well as raw material components The system technology BEUMER has developed a special technology for the utilization of alternative fuels in the high temperature 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 experience gained a standard of high quality and reliability could be achieved. The enclosed flow sheet illustrates clearly the way of the combustibles from their delivery up to the kiln inlet. Flow...

Economical utilization and sensible disposal of scrap tires The storage area Because of the increase in motorization, 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...

Scrap tires from delivery to the burning process The machine technology The handling of scrap tires requires a 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 conditions. 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 construction and function the single machine components must be suitable for the scrap tires of random size and...

Process of feeding the fuel into the kiln The design of the kiln inlet valve and its functional shape essentially depend on the type of fuel to be fed. Whole tires require a specifically different supply than for example shredded materials, the throughput capacity and the related calorific value determine the opening 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 valves or swivel valves. The upper and central step open and close in forced order to protect the kiln operation...

BEUMER system technology as installation concept for the thermal utilization of alternative solid fuels in the high-temperature process of rotary cement kilns Example of a project for the burning of shredded material and scrap tires Apart from scrap tires there is also a strong requirement for the thermal utilization of rubber shreds as well as other complementary combustibles which are mostly shredded such a synthetic materials, wood or oil saturated substances, mineral materials from the food industry and waste oil regeneration. Therefore, modern concepts aim at a flexible use with a...
