[0003] In the above configuration, the flue gas 17 generated in the furnace 21 of the boiler furnace 01 has an IDF09.
After the ash is removed by the ash collector 07 through the flue gas flue 06, the ash is sent to the AH08. . [0004] Combustion exhaust gas 17 sent to AH08
Is heated and heated to the combustion air 16 separately sent by the FDF 10 through the air duct 11, and then released to the atmosphere. On the other hand, the primary exhaust gas 18 branched upstream of AH08 passes through the primary exhaust gas duct 12
The coal 19 which is fed into the coal crusher 13 and which is separately fed to the coal crusher 13 is dried by the amount of heat carried in, thereby improving the crushing performance. Coal 19 finely pulverized by the coal pulverizer 13 is sent to the pulverized coal nozzle 05 through the pulverized coal supply pipe 15 as the pulverized coal mixture 20 together with the primary exhaust gas 18 by the coal removal machine 14 and then into the furnace 21. It is blown. A pulverized coal mixture 20 injected into a furnace 21
Is ignited by an ignition source (not shown) to form a flame 22. [0008] Combustion air 16 heated and heated by AH08
Is blown into a burner wind box 02 and blown into the furnace 21 from the pulverized coal air nozzles 03 and the air nozzles 04 arranged as shown in FIG. 4 to continue burning the formed flame 22. [0009] In the case of using coal having a high volatile content and high moisture content, a large amount of heat is required for drying in the coal crusher 13 when the coal is crushed by the coal crusher 13. Therefore, a high temperature primary exhaust gas 18 is required. However, since the coal 19 has a high volatile content, if the oxygen concentration of the primary exhaust gas 18 is high, a fire or explosion occurs in the coal pulverizer 13, and when pulverized coal is deposited on the pulverized coal supply pipe 15,
There is a possibility that overheating and burning of the pulverized coal supply pipe 15 may occur. Conventionally, in order to prevent the above-mentioned overheating and burning, the oxygen concentration in the high-temperature primary exhaust gas 18 has been reduced to several percent before use. As a result, the combustion speed of the pulverized coal mixture 20 is reduced to about 1/6 that of the case where fresh air having an oxygen concentration of 21% is used for the primary exhaust gas 18, and the flame 2
In order to form No. 2, it was necessary to use a strong ignition source as a stabilizer. [0011] In order to solve the above-mentioned problems, the present invention aims to solve the above problems by using coal used as fuel and a combustion furnace.
And al of the high temperature exhaust gas fed to the coal pulverizer, the pulverized coal as well as pulverized coal is transported by the exhaust gas, pulverized coal mixture comprising the finely ground coal and gas

In front of the fresh air cylinder, combustion air is
A pulverized coal air nozzle is provided which blows air into the inside of the pulverized coal nozzle so that fresh air having an oxygen concentration equal to or higher than the atmosphere can be blown from the fresh air chamber through the fresh air injection nozzle to the pulverized coal mixed air outside surface side. A coal-fired burner characterized by having a high volatile content and a high moisture content is provided. As described above, the present invention provides a plurality of fresh air injection nozzles along the inner wall surface of the pulverized coal nozzle,
The oxygen concentration on the surface side of the pulverized coal mixture is increased, and with such a configuration, the pulverized coal mixture flowing through the pulverized coal mixture passage near the tip of the pulverized coal mixture is supplied to the inside of the pulverized coal nozzle. Fresh air having an oxygen concentration higher than that of the atmosphere is blown from a fresh air inlet nozzle provided in contact with the wall surface to form a pulverized coal mixture layer having a high oxygen concentration on the surface side of the pulverized coal mixture. The pulverized coal mixture blown into the furnace from the pulverized coal nozzle ignites the high oxygen concentration layer on the surface side by the ignition source, and the volatile component combustion starts first. Subsequently, diffusion mixing of the combustion air supplied from the pulverized coal air nozzle and the pulverized coal mixture proceeds, and combustion near the ignition portion is continued. As a result, a stable flame is formed. Embodiments of the present invention will be specifically described below with reference to the drawings.
