摘要： PURPOSE: To reduce the generation of NO
x easily and effectively by a method wherein fuel and combustion air are supplied into a furnace through separate ports respectively, and a flame is maintained by a flame maintaining burner.
CONSTITUTION: A boiler 1 has the furnace 1a, a pair of heat exchangers 1b and 1c, an air preheater 2 and a chimney 3. The fuel is thrown into the furnace 1a through fuel supply ports 4a, 4b and 4c having fuel injection pipes and attached at the tip of a fuel supply line for denitration combustion. On the other hand, a combustion air is introduced into the furnace 1a via independent double-staged combustion air ports 5a, 5b and 5c. The flame maintaining burner 8 functions to stabilize the combustion within the furnace.

摘要： PURPOSE:To reduce generation of NOx, by selecting the rate of a two-stage combustion to be greater than 20%, and making the average excess air ratio at an upstream burner section greater than that at a downstream burner section. CONSTITUTION:A burner shown in the drawing is supplied with fuel from a fuel supply line 5 and combusting air from a combusting-air supply line 6, respectively. Here, arrangement is such that the amount of fuel and that of combusting air supplied to a plurality of burners are both made different. That is, the average excess air ratio at an upstream burner section, determined by the amount of fuel (Fa+Fb) and the amount of combusting air (Aa+Ab) supplied to upstream burners 4a, 4b is made greater than that at a downstream burner section, determined by the amount of fuel (Fc+Fd) and the amount of combusting air (Ac+Ad) supplied to downstream burners 4c, 4d. With such an arrangement, it is enabled to reduce generation of NOx.
