Strengthen the operation and adjust the wind and coal slurry ratio and the slurry gun's retreat. (1) Maintain the furnace negative pressure at -20Pa; (2) Maintain the furnace outlet flue gas oxygen content in the range of 3.5% to 4.3%. In order to supply sufficient air volume to ensure complete combustion of the coal water slurry; (3) the input of the burner should be as uniform as possible, and the air distribution should be appropriate to weaken the residual of the tangential twist and maintain the temperature difference between the two sides of the boiler. More than 25 ° C; (4) adjust the wind and coal water slurry ratio according to the table parameters and the operation mode of the burner. First set the opening degree of each damper (according to No. 1 / No. 3, No. 2 / No. 4 diagonally, weaken the residual of the tangential twist and reduce the smoke temperature deviation); then press the layer ※ middle layer ※ upper layer The “pyramid†sequence is fed into the pulp gun in a diagonally symmetrical manner, which reduces the height of the flame center; then adjusts the amount of pulp in each layer and corners, and distributes the 220t/h boiler in the Maoming Thermal Power Plant to the superheater after burning the coal slurry. Super temperature analysis and technical transformation, fine adjustment of slurry pressure and steam pressure matching of each slurry gun to ensure good atomization. After the technical transformation and adjustment of the above several aspects, the comparison of the operating parameters before and after the boiler reform, the superheater wall temperature did not exceed the upper limit of 560 ° C, the amount of desuperheated water was 2.36 t / h, which proves that there is adjustment room. The temperature of the smoke on both sides of the exit of the furnace was measured by an infrared thermometer to be 1012 ° C and 1045 ° C. Compared with the 1113 ~ 1173 ° C before the transformation, the flame center was moved downward, and the data and the operating data of the above table were also It reflects that the smoke temperature deviation has decreased. With the normal operation of the heated surface soot blowers, the ash accumulation on each heated surface of the boiler is significantly reduced, ensuring continuous and stable operation of the boiler for a long period of full load.
