| Target characteristics and specification of parameters for a 3 MW rated biomass-fired steam turbine system would typically be:
The basic elements of a biomass-fired steam turbine technology system are typically:
In looking at the choice of appropriate technologies, attention has to first be made to whether the unit is to serve the community directly in an off-grid capacity or whether the intention is to establish a commercial unit capable of feeding the grid. This aspect is considered from the following links. From this page, the types and units available and the variables that need to be considered and issues related to connectivity is made, as well as a review of future trends in generation within the Sri Lanka context. More information on grid connection and off-grid generation As part of the whole issue of planning the future location of dendro-power units (whether they be linked to the grid or to serve a community with no short-medium term expectation of being connected to the national grid), there are a series of variables that need to be considered: for example; population distribution, land availability for fuelwood production, growth conditions for the crop (rainfall, soils) as well as the perceived demand and interest of the community is taking part in such a venture. One way of assisting in national and regional planning is to overlay as many of these variables as we can in the form of Geographical Information System (GIS) and to get a combined integrated view of what seems to be the most economically viable locations. As well as the role of wood and agricultural waste in the development of electrical power, an important aspect is the continuing role of such material for heat energy. This is particularly important in S. Asia where fuelwood and such material as rice husk has been used for tea and tobacco drying. Further consideration of the industrial use of heat energy is provided with particular emphasis on the situation in Sri Lanka. More Information on industrial heat energy In terms of the overall energy budget, the use of wood still dominates the energy equation of most developing countries. This particularly relates to the household sector and small enterprises making use of wood for cooking and fuelling kilns. An analysis of the household sector is provided for Sri Lanka including an assessment of the role of biogas. More Information on the household sector As the cost of fossil fuels become more and more expensive,
the economics of using biofuels becomes more desirable. In Europe, a
directive on the Promotion of the use of Biofuels for Transport proposes
a target of 5.75% for the share of biofuels to be used in the transport
sector by 2010. In Cambodia for example, there has been recent interest
in the use of the crop Jatropha curcas for bio-diesel as well
as in such places as Indonesia and India. This is discussed further
in a paper prepared by Andrew Williamson of the Cambodian Research Centre
for Development. Consideration of the issues related to the development of bio-fuels for Sri Lanka are considered further on the webpage covering The Transport Sector. More information on the Transport Sector
