After nitrification technology transformation for 5 boilers of Guangzhou Power Plant

such main problems as severe slagging and ash deposition in furnace

relatively high water temperature at the economizer outlet

output reduction of the pulverizing system

shortening life of the tertiary air burner and bad effect of NH3 escape on downstream equipments occurred during the boiler's running.Thus

corresponding measurements were presented

for example

prohibiting combustion of coals with low melting point or high moisture

strengthening soot blowing

avoiding simultaneous running of double milling systems

reconstructing the tertiary air system

and so on.
