In this Section we look at some
of the issues that relate to the use of wood and biomass for the production
of heat energy, which can be used directly as part of an industrial
process or used in the production of electricity. In Sri Lanka the use
of biomass is as follows: -

The attached paper examines the choices in approach
available for the combustion of biomass and different ways it can be
handled.
Major factors influencing design of equipment are:
- Fuel properties (e.g. bulk density, moisture, proximate
and ultimate analysis, calorific value, ash properties, and size characteristics)
- Thermal requirement (e.g. heat load, processing temperature,
furnace and heat exchanger design, etc.)
- Economics (e.g. cost of available fuels, labour rates,
equipment costs)
- Local factors (e.g. operational and construction/maintenance
skills, spares availability, roads and local infrastructure, environmental
legislation)
