Comportamiento de Cenizas y su Impacto en Sistemas de Combustión de Biomasa.

Biomass as a source of energy is key to the progress of developing countries like Uruguay, since the application of a safe and efficient burning technology uses a renewable source of energy, relieves the dependence on imported crude oil, generates more employment than traditional sources and has a zero net greenhouse gas effect. Knowledge of the characteristics of the fuel and its behaviour in combustion systems is very important, since the installations are subject to chemical and physical attack from its ashes. The ash content and composition must be measured and analyzed, and its impact evaluated. In particular, cereals and other short-rotation plants have ashes with a high tendency to form deposits and enhance corrosion processes. This paper focuses on the effects that some kinds of fuels have on the physical and chemical damage of boiler components, particularly Chlorine enhanced corrosion. Recommendations for the remediation of critical situations are provided. [ABSTRACT FROM AUTHOR]
