Abstract:
Biomass heating generation has been extensively positioned as a strong market in many European Countries. Nevertheless, it can result into a source of undesired air pollutants, such as particulate matter (soot and ash particles) and also including products of incomplete combustion, such us carbon monoxide (CO) as well as volatile organic compounds (VOC). The latter are especially hazardous due to may cause negative health effects which varies greatly from those that are highly toxic to those with no known health effect. Due to the VOC impact, stricter emission limits have been set by the European standard EN 303-5:2012 for residential boilers up to 500 kWth. As a result of the current situation, the Spanish sector governments and industries are investing to develop high performance technology focused on the achievement of zero emissions. To be successful on the VOC reduction task according to the EN-303-5 restrictions, it is needed to attain a deeper knowledge on the VOC formation influencing factors. It has been identified that VOC emissions vary significantly depending on fuel, boiler design and operation conditions. Accordingly, objectives of the paper were: i)To present an overview of the more relevant conditions that affect VOC formation and ii) To present VOC emissions results when burnt woody reference pellets into a study-case 32 kWth grate-fired boiler. This paper is presented as an attempt to evaluate effects of those factors on VOC emission formation and to identify key aspects to attain a higher performance technology.
