Behavior of black liquor nitrogen in combustion : formation of cyanate
Report / Åbo Akademi, Process Chemistry Centre : 14-2 (Åbo Akademi - Åbo Akademi University, 05.12.2014)The Kraft pulping process is the dominant chemical pulping process in the world. Roughly 195 million metric tons of black liquor are produced annually as a by-product from the Kraft pulping process. Black liquor consists ... -
Chemistry of potassium halides and their role in corrosion in biomass and waste firing
Åbo Akademi, Faculty of Science and Engineering, Johan Gadolin Process Chemistry Centre : 16-02 (Åbo Akademi - Åbo Akademi University, 17.06.2016)Compared to the use of traditional fossil fuels (coal, oil, natural gas), combustion of biomass and waste fuels has several environmental and economic advantages for heat and power generation. However, biomass and waste ... -
Combustion properties of biomass residues rich in phosphorus
Report / Åbo Akademi, Process Chemistry Centre : 12-02 (Åbo Akademi University, Process Chemistry Centre, 04.04.2012)The currently-used sources of biomass are limited so new ones are required in order to meet the European Union target and to satisfy the constantly-increasing demand for energy. This is why energy recovery from residues ... -
Effects of Temperature Gradient on Ash Deposit Aging and Heat Exchanger Corrosion
(Åbo Akademi - Åbo Akademi University, 22.11.2019)Boilers firing biomass and/or waste-derived fuel have in general lower electrical efficiencies compared to coal-fired boilers. The root cause for the lower electrical efficiency lies in the high-temperature corrosion of ... -
