循环流化床锅炉微流化点火技术的应用
摘要
神华新疆米东热电厂2×300MW机组循环流化床(CFB)锅炉采用微流化方式点火
整个点火过程床温温升率一直维持在1~3℃/min之间
瞬间最高达4.6℃/min
连续给煤前床温的平均温升率约为2℃/min
温升合理、可控。点火耗油量为9.03t
远远低于试运期间的点火耗油量
也低于我国其它同级别CFB锅炉点火过程的耗油量。
Abstract
The micro-fluidized ignition mode has been used onto CFB boiler of 2×300 MW units in Shenhua Midong Thermal Power Plant
the temperature-rising rate of bed temperature in the entire ignition process was keeping continuously within 1~3 ℃/min
the temporary highest temperature-rising rate was 4.6 ℃/min
the average temperature-rising rate was about 2 ℃/min.The said temperature-rising rate was reasonable and controllable
the oil consumption was only 9.03 t
being far lower than that in the trial operation period
also being lower than that used in ignition process of similar capacity level CFB boilers in the country.
