form agglomerates and to sinter between 900 ºC and 1000 ºC in combustion conditions. Coal and peat ashes are usually trouble free at these temperatures‚ even if the melting point temperatures are in the same range with biomass fuels. Coal or peat is co-fired with biomass in many multi-fuel fired boilers. The woody biomass ashes are in general much more reactive than the ashes of fossil fuels. Lower reactivity of coal and peat ashes is connected to a composition with mainly quartz and various silicate-based

Mining of uranium and coal to produce electricity have been more controlled through the years and the pollution produced has been minimized‚ but do require substantial rehabilitation of the areas mined. Then the burning of these fossil fuels have staggering effects on the environment. There is the release of carbon dioxide‚ and radioactivity into the environment. The radioactivity comes from both coal-fired and nuclear powered stations. When coal combustion is the source of electricity
