某热电厂通过采取压火时快速断煤和关停风机、保持压火前的高床温和适当的料层厚度等措施控制锅炉高水位和减少热量损失,实现了220 t/h循环流化床锅炉的安全压火;并通过设计煤种、提前脉动给、控制好一次风量来防止炉料降温过快,滞后30 s启动返料风机和二次风机来减少冷空气进入炉膛等一系列措施,顺利实现了220 t/h循环流化床锅炉临时检修时的热态启动。
A thermal power plant through the rapid suppression of fire when the pressure off the fan and shut down the fan to maintain pre-press high bed temperature and appropriate material thickness and other measures to control the high water level boiler and reduce heat loss to achieve a 220 t / h circulating fluidized bed boiler Safe fire suppression; and through the design of coal, pulsation to advance, control a good air volume to prevent the charge cooling too fast, lag 30s start back fan and secondary fan to reduce cold air into the furnace and a series of measures to achieve a smooth Hot Start of 220 t / h Circulating Fluidized Bed Boiler in Temporary Overhaul.
