Summary

Thermal treatment plant for technical rubber wastes UTRO-500 is designed mainly for average temperature (400–600 °C) thermal decomposition of worn-out tires in overheated aqueous vapour medium or vapor-gas mixture (aqueous vapour plus technical rubber gaseous decomposition products).The outcome of the process is composite liquid fuel and metallic scrap (if any metal is present in waste materials).

Description

The essence of the method is in special heat treatment of technical rubber wastes (worn-out tires) resulting in rubber thermolysis and generation of solid, liquid and gaseous phases.
The resulting rubber waste thermolysis products are as follows:


Liquid waste thermolysis products are identical to mazut both in their composition and properties. Solid products are represented by carbonized matters (partially carbonized coal).
Mixing of liquid and solid products gives suspension (segregates) which is weakly stable if the component ratio is 70% (liquid) + 30% (solid) and is stable (no segregation) if the component ratio is 50% (liquid) + 50% (solid).
By its heat-producing value, sulphur and moisture content, viscosity and flash temperature, the composite liquid fuel (CLF) corresponds (almost identical) to M40 and M100 mazuts.
By its quality, the CLF is identical to carbon fuels of M100 mazut type and is suitable for use in liquid-fuel boilers both as a pure substance and mixed with other liquid fuels.
Taking into consideration ecological safety factor in fuel production process based on waste decomposition, it seems potentially worthwhile mixing the three following components to get the fuel: condensate (water), liquid fraction and solid residual matter. Sulphur content in the resulting fuel is between 0.05 and 1.26 wt %. On mixing 320kg of liquid fraction, 630kg of solids and 1100kg of water it is possible to obtain a fuel with a specific heat value of approximately 16,000 kJ/kg.
