- The paper concerns the impact of mild pyrolysis of coals on the possible mercury releases from the combustion process. It was proven that while mild pyrolysis may lead to the decrease of mercury content in solid fuel (from 0 do even 80% of dry mass), the resulting increased SO2HCl ratio in flue gasses may be disadvantageous in the case of the mercury oxidation as well. Hoverer, when optimised, for analysed lignites, this type of thermal precombustion technique could satisfy up to 4-26% of mercury decrease requirements while for analysed hard coal it seems to be pointless to adopt it within power plant. Therefore, the environmental benefits of mild pyrolysis will be strongly depend on the type of fuel (i.e. mercury compounds in dry matter) and the conditions (time, temperature) of the process.
