process for operating a coal-fired power plant combustion system, and the application of this method

摘要

The invention concerns a process for operating a coal-dust fired power plant in environmentally sound fashion and arrangements for accomplishment of the process pursuant to the invention. The same relates in particular to the reduction of the emission of gases harmful to the environment such as NOx and SO2. A particularly surface-active coal dust is used and is heated extremely rapidly in a burner muffle before being mixed with combustion air. After combustion the flame gases are very rapidly cooled down to a temperature under 1000 DEG C. before being discharged from the burner muffle.
