Abstract
Today, the world is implementing the use of green energy in promoting renewable
energy. Mostly, the interest lies in the depletion of fossil fuel and the environmental
degradation which has prompted the use of biomass as a source of energy. A suction
biomass gasifier was thus selected for energy conversion due to reliable in thermal
output, broad range of fuel sizes and the output producer gas with less tar content.
The gasifier was designed with an inner diameter of 350mm, 1.1m in height and has
a 25kW thermal output. It is attached to a gas cooling and cleaning system (GCC) to
remove some of the particulate, water vapor and tar. In the study, a suction biomass
gasifier was used to carry out the gasification experiments using wood waste and
connected to a diesel engine-generator to generate electricity. Wood chip has a low
calorific value, LHVBiomass of 17.92MJ/kg while producer gas has a typical LHVPG of
4.2MJ/Nm3. Diesel generators with 5.5kWe (rated speed of 1500rev/min) was used
for the dual fuel experiment. In dual fuel mode operation, diesel displacement was
60% at partial load (1500 rev/min). Results show that the emission levels of carbon
monoxide (CO), carbon dioxide (CO2) and unburned hydrocarbon (HC) are
relatively higher than neat diesel. However, NOX emission of dual fuel mode is
always lower than neat diesel. Available alternative fuel is palm oil with high energy
content that can be adopted as an alternative to petroleum based fuel. Research was
carried out to evaluate the performance and emission by experimenting on palm oil
as fuel in diesel engine.
