The large-scale implementation of bioenergy demands solid biofuels which can be transported, stored and used efficiently. Torrefaction as a form of pyrolysis converts biomass into biofuels with according improved properties such as energy density, grindability and hydrophobicity. Several initiatives advanced this development. The first pilot-scale and demonstration plants displayed the maturity and...
Combustion tests have been performed in a 500kW pulverized coal furnace in order to investigate the cofiring characteristics of torrefied spruce and bituminous coal (El Cerrejon coal from Colombia). Monocombustion test cases for the coal and torrefied spruce were also performed for a comparative evaluation. Measurements performed include burn-out, gas temperature profiles and emissions characteristics...
The study investigates cofiring characteristics of torrefied biomass fuels at 50% thermal shares with coals and 100% combustion cases. Experiments were carried out in a 20 kW, electrically heated, drop-tube reactor. Fuels used include a range of torrefied biomass fuels, non-thermally treated white wood pellets, a high volatile bituminous coal and a lignite coal. The reactor was maintained at 1200 °C...
NO and NO2 formation in PF oxy-fuel firing was investigated for a high volatile bituminous coal and a high-sulfur lignite coal. Results obtained under various oxy-fuel atmospheres were compared with those produced during air combustion. Experiments involving NO injection under dry and under wet conditions were also conducted in order to simulate dry and wet flue gas recycles respectively. NO emissions...
