Evaluation of boiler performance with using of bio-ethanol absorbed wood pellets

Abstract

In current trends the wood pellets are very significance role in the replacing of boiler fuel; it is a surrogate and renewable fuel. For this study comparative analysis of the fuel performance in the boiler is carried out effectively. Two categorize of fuel like as raw wood pellets and wood pellets are immersed in the bio- ethanol are taken to this experimental work. The thermal characteristics and thermal efficiency of the boiler with influence of two types of fuels are conducted efficiently. Normally the wood pellets having small pores it is used to absorb the bio ethanol while in immersion. Amid in the two fuels, wood pellets immersed in the bio ethanol are provided and increase the thermal properties as well as thermal efficiency compared to raw pellets. The flue gas constituent?s percentage such as carbon monoxide, oxygen, carbon monoxide and nitrogen oxides are analyzed, additionally the high temperature of flue gas also measured in the outlet of the chimney. No alteration is made in the boiler setup which is comfortable to both fuels.
