Abstract:
The wooden railroad ties have a lifespan of approximately 50 years. When replaced, they need to be stored and destroyed very carefully because they are impregnated by creosote and polluted by the rail use. In combustion applications of this biomass, the pollutants, mainly polycyclic aromatic hydrocarbons and heavy metals are freed restricting the energetic valorization of crossties to incinerators equipped with suitable flue gas treatment. As an alternative, this paper presents the results of an experimental study on the gasification of creosoted wooden crossties and the subsequent combustion of the gas in a cogeneration engine. The experiments are focused on the similarities with natural wood gasification in a fixed bed downdraft gasifier to validate this conversion route and on the emissions of pollutants at the exhaust of the engine. It is shown that, without specific exhaust gas treatment, the emission regulations are respected.
