Abstract
Steam plays a substantial role in several industrial
processes and is usually required in significant
amounts to enable continuous production in
beverages, dairies, flower farms, and many other
agro-processing industries. Currently, the
predominant method for steam generation in such
industries is by using furnace oil to fire boilers
that generate the required steam. This technique
has negative environmental and economical
consequences, whose impact is felt especially in
developing countries like Uganda.
In order to become competitive both locally and
internationally, there is need to develop a
sustainable technology, which is economically
viable, environmentally friendly and provides the
steam requirements appropriate for the various
industrial applications mentioned above. The
solar technology will utilize the considerably high
insolation of Uganda which is approximated at
157kWh/m2
per month. This insolation is ten times
more than that in London and seven times more
than that in Vienna or Berlin.
This paper reports on the development of a solar
water heater concentrator for use in industries in
Uganda. The issues tackled in this work are:
different reflective materials, heating fluids, the
combination of hybrid flat collector-cumconcentrator,
solar tracking possibilities versus
static ones, heat power measurement and
parabolic design, and economical viability study
It is expected that this study, done in cooperation
with Solar Construct (U), will create capacity to
have this type of solar-powered water heater
produced and utilized in Uganda to partially
replace furnace oil boilers as a more economical
alternative
