For the traditional coal-fired boilers, the boilers are a job that must be equipped. They not only need to ensure the safety of the coal-fired boilers, but also need to maintain the operation of the boilers. However, the new Shandong gas boiler has been operated all-weather unattended through the automatic control system, so how to achieve it?

在具有自动控制系统的锅炉中，内装了温度传感器，这些传感器在工作时就相当于我们的眼睛，负责将锅炉运行的情况通过数据的方式传递给锅炉上的控制器。比如，有一台锅炉设定的工作温度为55℃，锅炉运行时锅炉内的温度传感器采集到此时炉内的水温为40℃。这个温度数据发送到控制器后，控制判断此温度远未达到设定温度，于是受控的燃烧器继续以大火的状态加热锅炉内的水。

In boilers with automatic control system, temperature sensors are installed. These sensors are equivalent to our eyes when they work. They are responsible for transferring the operation of the boiler to the controller on the boiler by means of data. For example, there is a boiler set working temperature of 55 C, the temperature sensor in the boiler when the boiler is running collects the water temperature in the furnace at 40 C. After the temperature data is sent to the controller, the control judges that the temperature is far from the set temperature, so the controlled burner continues to heat the water in the boiler in the state of a big fire.

锅炉继续运行，温度传感器也在不断采集温度数据并传送到控制器，随着燃烧器的加热温度逐渐上升到53度。此时控制器通过设定温度与当前温度的比对，判断炉水接近设定温度，于是控制燃烧器减小火焰。随着温度越来越接近设定的55℃时，变频燃烧器能够根据实际的热量需求，精细的控制火焰大小，通过逐步接近，从而将温度维持在55℃上。当热量需求有变化时，火焰也会做相应改变，使锅炉仅工作在维持温度的状态。

As the boiler continues to operate, the temperature sensor also continuously collects temperature data and transmits it to the controller. With the heating temperature of the burner gradually rises to 53 degrees. At this time, the controller judges that the water is close to the set temperature by comparing the set temperature with the current temperature, and then controls the burner to reduce the flame. With the temperature approaching the set temperature of 55 C, the frequency converter burner can fine control the flame size according to the actual heat demand, and by gradually approaching, the temperature can be maintained at 55 C. When the heat demand changes, the flame will change accordingly, so that the boiler only works in the state of maintaining temperature.

传统锅炉普遍使用的为三段火（大火、中火、小火），对于某些情况如，热量需求恰好比中火要大但是又远未达到需要大火加热的地步，此时控制器仍会继续使用大火加热，此时温度将快速上升，很快超过设定温度。此时控制器检测到水温已超过温度，于是控制燃烧器改为小火。然而小火又不能满足热量需求，此时锅炉水温就会下降，当下降到一定程度，控制器又将小火转为大火加热。此种方式相比变频控制，不仅温度存在波动，而且有一定的空烧浪费燃气的现象。

Traditional boilers generally use three-stage fire (big fire, medium fire and small fire). For some cases, the heat demand is just larger than that of medium fire, but far from the point where large fire heating is needed. At this time, the controller will continue to use large fire heating. At this time, the temperature will rise rapidly and soon exceed the set temperature. At this time, the controller detects that the water temperature has exceeded the temperature, so the burner is controlled by a small fire. However, the small fire can not meet the heat demand, at this time the boiler water temperature will drop, when it drops to a certain extent, the controller will turn the small fire into the big fire heating. Compared with frequency conversion control, this method not only fluctuates in temperature, but also wastes gas in air combustion.
