Low-grade fuels. Vol. 2

The Symposium on Low-Grade Fuels was held in Helsinki on June 12-16, 1989.The Symposium was organized by the Technical Research Centre of Finland in cooperation with the Finnish Ministry of Trade and Industry.The occasion gathered together specialists from 19 countries to exchange experience and information about low-grade fuels.These fuels, for example, lignite, peat, wood, industrial byproducts, waste, etc., are in many areas important local energy sources.However, they have often a high moisture or ash content or a difficult ash behaviour, which make them low-grade fuels, although their organic constituents may be of prime quality.The common goal was to minimize operational problems and environmental consequences of using these difficult fuels.The programme consisted of an Introductory session and of technical sessions on Combustion of Low-Grade Fuels, Gasification of Low-Grade Fuels, Behaviour of Low-Grade Fuels during Handling, Ash Behaviour, and Environmental Aspects Related to the Utilization of Low-Grade Fuels.Poster presentations were also held.
