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. Wood pellets immersed in the bio ethanol are provided and increase the thermal properties as well as thermal efficiency com-pared to raw pellets, due to amid in the two fuels. The flue gas constituent’s percentage such as CO2, O2, CO, and NOx are analyzed, additionally the high temperature of flue gas also measured in the outlet of the chimney. No alteration is made in the boiler set-up which is comfortable to both fuels.
