Biomass is a composition of various types of waste materials that can be utilized as useful form of energy. However this new kind of energy hasn’t met its full potential in production of energy especially electricity generation due to its lower performance in terms of thermal efficiency. Algae and microalgae have been treated as the source of bio-fuel and some algae also used in fermentation for bio-gas and other phase of energy. In this paper we selected the freshwater microalgae “Chlorella Vulgaris” as the main material and mixture with fecal sludge. We used the mixture as biomass fuel and combusted in the boiler system to analysis its heating performance. We found out the mixture material combusted in the boiler system, the outlet gas temperature is up to 700 °C and the emission gas components are in a trend with time serious. The results in this paper will be used as a reference material for microalgae multi-oriental energy application and biomass composition proximate and ultimate research development in the future.

Abstract


Biomass is a composition of various types of waste materials that can be utilized as useful form of energy. However this new kind of energy hasn’t met its full potential in production of energy especially electricity generation due to its lower performance in terms of thermal efficiency. Algae and microalgae have been treated as the source of bio-fuel and some algae also used in fermentation for bio-gas and other phase of energy. In this paper we selected the freshwater microalgae “Chlorella Vulgaris” as the main material and mixture with fecal sludge. We used the mixture as biomass fuel and combusted in the boiler system to analysis its heating performance. We found out the mixture material combusted in the boiler system, the outlet gas temperature is up to 700 °C and the emission gas components are in a trend with time serious. The results in this paper will be used as a reference material for microalgae multi-oriental energy application and biomass composition proximate and ultimate research development in the future.
