燃烧系统流量控制方法
摘要：
本发明公开了一种燃烧系统流量控制方法，尤其是一种在镀锌或连退机组加热段用的燃烧系统流量控制方法。本发明提供了一种能使燃烧系统快速达到稳定状态的燃烧系统流量控制方法，包括以下步骤：A、首先测得温度和压力稳定时燃气流量调节阀与空气流量调节阀的开度；B、在进行燃烧前，将燃气流量调节阀与空气流量调节阀的开度设定到温度和压力稳定时开度的80％-100％，使得燃气在此开度下进行燃烧；C、进行燃烧并运行PID控制系统，PID控制系统根据负荷和工况的变化，利用燃气流量调节阀与空气流量调节阀对燃料和空气流量进行增加或减少，调整温度以及出现的温度偏差，从而使整个燃烧过程达到稳定燃烧。
摘要（英）：

The invention discloses a flow control method of a combustion system, in particular relating to the flow control method of the combustion system used in galvanization or a heating section of a continuous annealing unit. The invention provides the flow control method of the combustion system which can help the combustion system reach a stable state rapidly, comprising the following steps: A. firstly measuring opening of a gas flow regulating valve and an air flow regulating valve in the case of stable temperature and pressure; B. setting the opening of the gas flow regulating valve and the airflow regulating valve to be 80%-100% of the opening in the case of stable temperature and pressure before burning for realizing gas combustion at the opening; and C. burning and operating a PID control system which increases or decreases fuel and air flow and adjusts temperature and temperature deviation by the gas flow regulating valve and the air flow regulating valve according to change of load and operating conditions so that the whole combustion process reaches a stable status.
