To ensure maximum efficiency and reliability of the boiler plant operation, two requirements are
of paramount importance, the air to fuel ratio and the target temperature or pressure:
为确保锅炉设备运行的*大效率和可靠性，油气比和目标温度或压力这两项要求非常重要。
 The air to fuel ratio must be kept to the minimum to ensure complete combustion within the
limitations of the combustion head design. A very high air to fuel ratio will be an indication of
high excess air, which decreases the overall efficiency of the boiler. The fuel valve and air
damper positions set for this minimum air to fuel ratio along the whole commission curve
must be infinitely repeatable to an incredibly high degree of accuracy.
 油气比必须保持*小，从而确保在燃烧头设计限值内充分燃烧。较高的油气比表明有较高的过
剩空气，这样会降低锅炉的整体效率。沿整个调试曲线设定*小的油气比时燃油阀和空气阻尼
器位置必须能够无限重复，到达*高的精确度。AUTOFLAME低氮阀门执行机构MM10004参数设置, 微型控制系统
 The target temperature or pressure of the boiler should be monitored by the combustion
system and at all times, with exactly the right amount of fuel and air fired to achieve this
target value. Irrespective of load changes, the burner/boiler system should be able to meet
the target temperature or pressure.
 锅炉的目标温度或压力应通过燃烧系统进行监控，始终用正确的燃料和空气量达到目标值。无
论负载如何变化，燃烧器或锅炉系统应能满足目标温度或压力要求。
The burner’s fuel to air ratio was traditionally governed by mechanical systems which involved
multiple cams, shafts and linkages controlled by one motor. The inherent hysteresis that
occurred from the system design allowing components to be loose, which made the level of
accuracy required impossible. With this poor accuracy, the response of the fuel input to the
monitored temperature/ pressure of the boiler meant that the set target value at most times would
overshoot or fall short.
燃烧器的油气比通常由机械系统控制，机械系统包括由一个电机控制的多个凸轮、轴和连杆机构。
因系统设计允许组件松动，因此产生的固有滞后现象则无法到达要求的精度，燃油输入要达到锅炉
的监控温度或压力则意味着设定的目标值在大多数情况下会过高或下降。
The Micro-Modulation module is the basic building block of the Autoflame System. The
Autoflame M.M. module provides an easily programmable and flexible means of optimising
combustion quality throughout the load requirement range of the burner/boiler unit whilst
ensuring the temperature is accurate to within 1°C (°F) and pressure to within 1 PSI (0.1Bar).
Using direct drive motors to individually control the air damper and fuel valve(s), gives the
optimum combustion of the burner at every point along the firing range. The allowed error in
angular degrees of rotation between the two servomotors at any position in the load range is 0.1°.
微型控制模块是Autoflame系统的基本构建块，Autoflame微型控制模块根据燃烧器或锅炉部件的负
载要求范围为优化燃烧质量提供一个易于编程的灵活方式，确保温度精确到1°C（°F）、压力在1 PSI
（0.1bar）。使用直接驱动电机单独控制空气阻尼器和燃油阀可以使燃烧器在燃烧范围内各点都实
