Study on Thermal Characteristics of Waste Wooden Sleeper

Abstract

The wooden sleeper laid in the railroad is highly contaminated by the preservative such as creosote used in the production process. And the secondary contamination of wooden sleeper happened from the leakage of diesels and lubricant oils. Recently the concrete sleeper has replaced the wooden sleepers. But the wooden sleepers are still used and the huge amount of waste wooden sleeper are discharged every year. Due to the environmental toxicity of contaminants in waste wooden sleeper, the waste wooden sleeper is categorized as the specified waste and its disposal should be carefully conducted. But there is not alternative method except the incineration. In this study, the thermal extraction characteristics of waste wooden sleeper in high temperature were investigated to observe the feasibility of the disposal and reuse of waste wooden sleeper.
