I. INTRODUCTION
II. GENERAL SITUATION OF BOILER
Coal-fired utility boilers are big users of energy The boiler studied in this paper is a coal-fired utility boiler,
consumption, whose pollutant emission, especially nitrogen N300-165/535/535, evaporation capacity is 1025 t/h with a 300
oxide (NOx), sulfur dioxide (SO2) and soot is serious, which MW condensing generator. De
