Title: Improvement of the process of fuel firing on BKZ-210-140F boilers

Abstract

The existing flame processes of dual firing of gas and solid fuel are updated with reconstruction of the burners at the Chelyabinsk TETs-2. This is connected with marked worsening of the quality of local coal supplied to the cogeneration plant. Comparative tests of boilers with burners subjected to different degrees of updating have shown that replacement of the now used swirled method of introduction of reagents into the furnace by a uniflow one lowers the heat flows to the metal structures and to the settling of the burner throats making them more reliable. The emission of nitrogen oxides is minimized in the mode of gas firing and the activity of slagging of the furnace and of the platens is reduced in the mode of coal firing, which makes it possible to raise the steam rate of the boiler. Ways for further improvement of burner design with respect to nitrogen oxide emissions in the polydisperse flame are outlined.
