分析了锅炉煤仓塞煤的原因和煤仓塞煤对锅炉运行的不利影响。以中速磨正压直吹制粉系统为例,通过引入锅炉负荷信号,采取提前预判的控制策略,配合一种专门解决煤仓塞煤问题的新型专利产品——煤仓疏松机,不仅能从根本上解决煤仓塞煤问题,而且能够保证调节系统的灵敏度及疏松器的安全强度。 The reasons for the stuffed coal in the boiler coal bunker and the unfavorable influence of the coal cofferdam on the boiler operation are analyzed. Taking medium-speed mill direct pressure pulverized coal injection system as an example, by introducing the load signal of boiler and taking the control strategy of pre-judgment, in cooperation with a new patented product - coal bunker loosening machine, Can fundamentally solve the problem of coal cofferdams, but also to ensure the sensitivity of the control system and the security strength of the loose device.
