Abstract
The world is faced with inadequate fuel supply for
household and industrial application. Fossil fuels are mostly used to
run machineries with the emission of carbon monoxide, carbon
dioxide, oxides of nitrogen, sulphur oxides and particulates from their
combustion affecting human health and the environment. Biomass
also forms a larger percentage of energy utilized in the household and
other areas. Apart from its emission after combustion, biomass waste
contributes greatly to pollution. One of the alternatives to effective
use of biomass such as rice husk waste is to generate electricity.
In this paper a review of energy production from biomass gasification
to run internal combustion engines is presented. The gasification
process is discussed under drying, pyrolysis, reduction, and
oxidation. Different types of designs of gasifiers are reviewed. The
current status of gasification technology in developed and developing
countries is discussed. The gas generated is introduced to a modified
engine with small amounts of diesel used to ignite the mixture. This
is because the producer gas cannot ignite by itself under the
prevailing pressure. Thus for a compression ignition engine to run on
producer gas they have to be either; a dual fuel engine or, converted
into a spark ignition engines. Since diesel engines have compression
ratios between 16 – 20 and are run at lower revolutions per minute
than gasoline engines they are ideally suited to run on producer gases
without spark ignition. The paper also looks at current work that has
been done and identifies areas that need further research.
