Fly ash from coal and biomass for use in concrete: Origin, properties and performance

Coal fly ash is widely used in as raw material in concrete industry because it can replace part of the cement and fly ash contributes to improve certain properties of concrete. As a way to reduce the contribution of coal fired power plants to the climate change, more and more coal is replaced by biomass. To keep fly ash as a valuable resource...

Combustion and co-combustion of biomass in a bubbling fluidized bed boiler

This PhD dissertation concerns the study of different aspects of biomass (co)-combustion in small-scale fluidized bed boilers for heat generation. The most renowned gaseous emissions from fluidized bed combustion, namely, CO and NO, are investigated with the help of experimental and theoretical studies. In addition, dust and metal emissions in...

Characterisation of supplementary fuels for co-combustion with pulverised coal

The current and future energy policy aims at increasing the share of renewable energy in worlds energy supply. One possibility to enhance energy production by renewable sources within a short term is co-combustion. This means co-firing biomass and waste with fossil fuels at existing power plants originally designed to fire fossil fuels. In...
