The content of water-soluble salts as potassium chloride (KCl) in straw may cause a number of different operational problems during the energy conversion in the plants. The content of potassiumn and
The project concerned production of liquid potassium fertilizer from straw fly ash. A pilot plant was established at the straw-fired boiler at Ensted Power Station, and, in 2007, the project succeeded
The objective was to monitor the corrosion rate of superheater tubes at different steam temperatures in a straw-fired plant in order to determine the optimal live steam temperature. This was done by
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.
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 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
