Abstract: PURPOSE:To reduce NO in the exhaust gas of a boiler without the modification of burners and a denitrification plant by a method wherein an exhaust gas mixing means, which mixes the exhaust gas of the boiler with the primary air supplied to a mill at the change of load, is provided. CONSTITUTION:When load changes, a primary air fan inlet damper 32 tends to supply the amount of air corresponding to the load of a boiler in accordance with a load requirement instruction signal and a mill primary air damper 7 is controlled in accordance with a fuel quantity requirement signal so as to tend to supply the air exceeding the quantity corresponding to the load of the boiler, resulting in being short to the amount of primary air to be supplied to a mill 3. The shortage of the amount of primary air causes to lower the outlet pressure of a primary air fan 6 and immediately to change the output of a subtractor 6. Said output controls the opening of a mixing damper 31 of primary air and exhaust gas through a proportional-plusintegral controller 41 so as to supply the amount of exhaust gas corresponding to the shortage of primary air amount through the mixing damper 31. Thus, NO can be reduced without the modification of burners and a denitrification plant.
