The purpose of this project was to improve our understanding of the characteristics and behaviour of char beds both in steady and unsteady operation. The knowledge gained is to be used for
The main conclusions of the survey are: The potential for biogas production from municipal organic waste in Malawi is scarce; The bioenergy potential of the Malawian agro-industries is large, with the
The study tours to Sweden, Finland, Austria, Italy and the USA have given a good insight in how the other countries are establishing the size classification of comminuted fuel.
In the work concerning experimental verification of thick airfoils, the focus has been on airfoils used by the industry. The method has been verified with measurements on a NACA 63-215 airfoil
The project is carried out by representatives of the EFP98 applicants who forwarded project proposals regarding concepts related to energy effective exploitation of waste waster sludge.
In this review a method for evaluation of these technologies is presented together with a spread sheet in which the method has been used for a number of the present conventional technologies. For the
The aim of the project is to encourage the exchange of experience, transfer know how to R and D in connection to extraction and utilization of landfill gas for energy purposes. The IEA-cooperation
The project objective is to develop more generally applicable assessment and design criteria for isolated power supply systems, and the expected result is a guideline for design of such systems.
The purpose of the project was to investigate how the rotor design of an existing wind turbine can be extrapolated to a 4 MW turbine. Within the project two optimization codes for optimizing a large
The purpose of this work is to develop a dewatering method that can dewater digested manure to a dry matter content that makes it possible to utilise the dry matter for energy production.
Char conversion during gasification was investigated. It was possible to model the conversion rate in a small fixed bed reactor, by using reactivity data. Tar reduction by partial oxidation was
Conservation of carbon stores in forest soils is important in order to maintain the fertility of soils and to avoid emission of carbon dioxide to the atmosphere. If bioenergy chips should be regarded
The aim of this project was to investigate if the biological methods, such as bioaugmentation of reactor with specific anaerobic, hydrolytic bacteria will improve hydrolysis of fibers and result in an
Transfer of technology and industrial cooperation require a common framework, thus a compilation and analysis of Russian wind load and other external conditions in relation to European wind turbine
The project constitutes a continously running 5 years research programme on aeroelasticity with the objectives to improve the basis for design and optimization of wind turbines, and establish an
The aim of the project was to develop and demonstrate an upscaled novel combustion process for waste and biomass based Combined Heat and Power plants - including the demonstration of excellent
Anaerobic biogas digesters are often manual regulated. This manual regulation is based on evaluation of data from the process, intuition, experience and rule of the thump. It is possible to transfer
This report discusses different methods of sampling and characterising of tar compounds undertaken by companies, institutes and universities dealing with thermal gasification technology and its
The purpose of the project is to develop and test micrometeorological tools for the prediction and estimation of properties of the wind that are important for loads on wind turbines situated on land
The purpose of the project is to perform an experimental investigation of extreme load on wind turbines, measuring both the wind field and the structural load response on high wind speed sites.
