Industrial Heat Energy
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:
- 1. Fuel properties (e.g. bulk density, moisture, proximate and ultimate analysis, calorific value, ash properties, and size characteristics)
- 2. Thermal requirement (e.g. heat load, processing temperature, furnace and heat exchanger design, etc.)
- 3. Economics (e.g. cost of available fuels, labour rates, equipment costs)
- 4. Local factors (e.g. operational and construction/maintenance skills, spares availability, roads and local infrastructure, environmental legislation)
