作为锅炉控制装置,其主要任务是保证锅炉的安全、稳定、经济运行,减轻操作人员的劳动强度。采用自动控制系统,能对锅炉进行过程的自动检测、自动控制等多项功能。锅炉控制系统,一般有燃烧、水位等控制系统。燃烧控制实质上是能量平衡系统,它以蒸汽压力作为能量平衡指标,量出而入不断根据用汽量与压力的变化成比例地调整燃料量与送风量,同时保证燃料的充分燃烧及热量的充分利用,其中保持合适的“空燃比”是一个重要因素。“空燃比”是指燃烧中空气量与燃烧量的比值系数。
As the boiler control device, its main task is to ensure the safety, stability and economy of the boiler and to reduce the labor intensity of the operators. Using automatic control system, the boiler can process the automatic detection, automatic control and many other features. Boiler control system, usually with combustion, water level control system. Combustion control is essentially an energy balance system that uses steam pressure as an energy balance indicator and measures the amount of fuel and air delivered in proportion to changes in the amount of steam used and the pressure continuously, while ensuring adequate combustion and heat of the fuel Full utilization of which to maintain a suitable “air-fuel ratio” is an important factor. “Air-fuel ratio ” refers to the ratio of combustion air volume and combustion ratio coefficient.
