摘要
介绍一种稳定可靠的新型一次风量测量装置,解决一次风量测量不准确的问题。并在此基础上介绍进一步优化控制的方案和参数,投入磨煤机一次风量自动控制系统。该自动控制装置投入后系统运行稳定,能够满足负荷指令大幅波动情况下,煤量变化对风量和温度的要求,提高了机组负荷响应速度,稳定了主汽压力,取得了较好的改造效果。
This paper introduces a more reliable, solves the problem of inaccurate measurement of primary ther optimize the control scheme and parameters of coal system. The automatic control system works stably, can stable primary air ,flow measurement device, which air flow. And on this basis, it discusses how to furmill, and be applied to a wind automatic control satisfy the the demand on air flow and temperature with coal load charge and greatly, improves the unit load sure, thus chieving better innovative effect. response speed, and stabilizes main steam pressure, thus chieving better innovative effect.
