催燃烧运行状态燃空比的调定,催化燃烧时的空气比值范围一般在4%~11%之间。在燃烧条件之下,能实现较好的催化燃烧效果,燃烧系统就可以得到热效率,同时又能取得较好的排放效果。
The range of air ratio in catalytic combustion is generally between 4% and 11%. Under the condition of combustion, the better catalytic combustion effect can be achieved, and the combustion system can obtain the thermal efficiency, at the same time, the better emission effect can be achieved.
燃烧起动过程通过紫外线传感器的检测到期小火点燃后,打开主燃气阀门。这时炉盘进行有焰燃烧,直到检测温度信号达到设定的点火关闭温度,点火阀门关闭,完成点火过程,进入到燃烧调节阶段。
The combustion start-up process is detected by ultraviolet sensor, and the main gas valve is opened after the small fire is ignited. At this time, the furnace plate carries out flame combustion until the detected temperature signal reaches the set ignition off temperature, the ignition valve is closed, the ignition process is completed, and the combustion regulation stage is entered.
当控制系统在待命的状态下,接到输入的起动命令,将进入燃烧运行状态,先是控制系统进行自检,之后进行前吹扫,变频器输出信号控制风机的旋转,空气风量由低速渐变为高速再逐渐变为低速,新鲜空气风吹过燃烧炉盘,以保证炉内没有残留燃气的存在,保证点火过程的可靠。

When the control system is in standby state, it will enter the combustion operation state after receiving the input starting command. First, the control system conducts self inspection, and then carries out front purging. The inverter outputs signal to control the rotation of the fan. The air volume gradually changes from low speed to high speed and then gradually to low speed. Fresh air is blown through the combustion furnace plate to ensure that there is no residual gas in the furnace Reliable ignition process.

可根据需要分别设定点火温度和变频器起动时的频率,控制风机的风量。点火温度是为了保证点火过程的可靠性。起动频率保证催化燃烧器在刚点燃时的有焰燃烧,这时的燃烧比不易太低,风量不能过大。
According to the needs, the ignition temperature and the frequency of the frequency converter can be set respectively to control the air volume of the fan. Ignition temperature is to ensure the reliability of ignition process. The starting frequency ensures the flame combustion of catalytic burner when it is just ignited. At this time, the combustion ratio is not easy to be too low and the air volume cannot be too large.
催化剂的加入并不能改变原有的化学平衡,所改变的仅是化学反应的速度,而在反应前后,催化剂本身的性质并不发生变化。催化燃烧设备主要由活性炭吸附箱、阻火器、热交换器,催化反应床,风机等主要部件组成。对催化燃烧设备选型要根据自身的需求来进行。
The addition of catalyst can not change the original chemical equilibrium, only the speed of chemical reaction, but the nature of catalyst itself does not change before and after the reaction. Catalytic combustion equipment is mainly composed of active carbon adsorption box, flame arrester, heat exchanger, catalytic reaction bed, fan and other major components. The selection of catalytic combustion equipment should be based on its own needs.
