NextGen BioWaste
The project NextGen BioWaste is a four-year integrated EU co-financed Research & Development project that started first of February 2006. With a total budget close to 30 million Euro, it is the biggest EU R&D project with focus on renewable fuels.
Vattenfall Research and Development was one of the initiators to the project. More than fifteen partners take part in the project, and four of them are from Vattenfall. The project objective is to improve electricity efficiency, reliability, performance and environmental compliance, to reduce costs at a competitive level for waste and biomass combustion plants that produce heat and electric power.
ChlorOut effective against corrosion
The main task for Vattenfall is to perform tests with additives and to show the benefits of using them. The sulphate-containing group of additives called ChlorOut is very effective in reducing corrosion and fouling of superheaters in biomass fired power plants. In NextGen BioWaste, ChlorOut will be used in waste fired boilers as well. Effects of additives on residue quality and extraction of heavy metals and chlorine from fly ash will be investigated. Vattenfall is also performing corrosion and deposit measurements in plants and as well as evaluation of new materials for super heaters. Effects of additives on residue quality and extraction of heavy metals and chlorine from fly ash will be investigated. Another task is development of improved control strategies for bio fuel plants.
Installation in Müllverwertung Borsigstraße (MVB), Hamburg
In the project NextGen BioWaste, Vattenfall will make a permanent installation of ChlorOut in aone of the boilers at the waste incineration plant MVB in Hamburg. Prior to the installation, extensive tests with ChlorOut were performed in the plant during 2006. The results from the tests have been used for designing the permanent ChlorOut system at MVB. The installation will be ready for operation in the end of 2007. Vattenfall New Energy and Vattenfall Power Consultant perform the work in cooperation with Vattenfall Research and Development.
