- Abstract
In order to obtain the effects on combustion in boiler when some parameters such as pulverized coal fineness, velocity of primary air mixed pluvesized coal particles change, testing on a 300MW power plant. The results illustrate that when fineness rised, temperature of gas center 0.4 meter apart from burner reduced to 536℃，unburned carbon in fly dust rised 4.1% and unburned carbon rised 6.8%, average temperature located A burner cross section decreased, average temperature located C burner cross section was almost invirant, average temperature located E burner cross section rised, average temperature located 30.5 meter cross section decreased; when the flow velocity rised, temperature of gas center 0.4 meter apart from burner reduced to 346℃，unburned carbon in fly dust rised 3.6% and unburned carbon didn’t have a obvious rule, average temperature located A burner cross section increased before decreasing, average temperature located C burner cross section rise alittle, average temperature located E burner cross section rised, average temperature located 30.5 meter cross section rised. Both parameters rised against ignation, unburned carbon in fly dust both rised, the temperature variation in boiler were different.
