电站锅炉风速在线监测系统设计

A Design of an on Line Monitoring System for Boiler Burning of Power Plant

本文讨论了基于单片机的电站锅炉风速在线监测系统的一种设计方法。它可用于监测锅炉燃烧,有助于司炉精确调节风量和煤粉浓度,并依据一次风管内风速的大小来确定风管内煤粉浓度的相对大小。实现锅炉一、二次风速实时、准确的测量,为电站锅炉的燃烧调整,提供科学的手段。结果显示这个系统将取得稳定燃烧和防止堵管的目的。系统设计充分考虑现场实际情况,如差压变送器量程、送风温度、一次仪表结构和管道等参数的影响,并在设计时采用模块化设计,使系统具有很大灵活性、适用范围广。

This paper presents a desig n of a distributed on-line monitoring system for boiler burning of power plant.It can be used to monitor the boiler operation and to help the operator to accurately adjust the quan-tity of wind and concentration of the pulverized coal.The result indicate that this system will achieve the purpose of stable burning and prevention from jamming of tubes.
