1、燃烧温度调理燃烧器温度调理能够通过文本显示器的键盘输入,改动变频器的输出频率,调理恰当的风量。当风量增大,燃烧温度超过设定值,则PLC操控变频器下降输出频率,减少出风量来安稳燃烧器 的温度。
1. Combustion temperature conditioning burner temperature conditioning can be input through the keyboard of the text display, change the output frequency of the frequency converter, and regulate the appropriate air volume. When the air volume increases and the combustion temperature exceeds the set value, the PLC controls the inverter to reduce the output frequency and reduce the air volume to stabilize the temperature of the burner.
若变频器输出频率低于设定值(风机出风量频率设为5Hz),而出风量仍高于设定值时,PLC开端,若在时刻内,下降到设定值,PLC抛弃,持续变频调速运转。
If the output frequency of the frequency converter is lower than the set value (the frequency of the fan output air is set to 5Hz), and the output air volume is still higher than the set value, the PLC starts timing. If it drops to the set value within the time, the PLC discards the timing and continues to operate with frequency conversion and speed regulation.
若在时刻内温度仍高于设定,PLC将持续调理,直至到达设定值。由PLC经PID运算后控变频器的频率输出;如温度不行,则频率上升,延时坚持时刻。反之亦然。
If the temperature is still higher than the set value within the time, PLC will continue to adjust until the set value is reached. The frequency output of frequency converter is controlled by PLC after PID calculation; if the temperature is not good, the frequency will rise and the delay will persist. vice versa.
2、燃空比的调定有文献标明,催化燃烧时的"燃气/空气比值"范围一般在4%~11%之间;在燃烧条件之下,燃/空比为6%时,就能实现较好的催化燃烧作用,燃烧体系就能够热效率,同时又能取得较好的排放作用。
2. The setting of fuel air ratio has been indicated in the literature that the range of "gas / air ratio" during catalytic combustion is generally between 4% and 11%; under combustion conditions, when the fuel / air ratio is 6%, better catalytic combustion can be achieved, and the combustion system can achieve thermal efficiency and better emission effect.

本体系的燃气-空气比的调理是通过零压阀实现的。当改动风机的空气风量时,燃/空比也能随之被改动,以到达催化燃烧器燃烧作业的要求。在起动时只要调理输出变频器的频率就能到达燃烧时要求的从有焰燃烧到催化燃烧的燃/空比的变化。
The gas air ratio of the system is regulated by zero pressure valve. When the air volume of the fan is changed, the fuel / air ratio can also be changed to meet the requirements of catalytic burner combustion. In the start-up, as long as the frequency of the output converter is adjusted, the fuel / air ratio change from flaming combustion to catalytic combustion can be achieved.

3、燃烧起动进程:当操控体系在待命的状况下,接到输入的起动指令,将进入燃烧运转状况,首先是操控体系进行自检,之后进行吹扫,变频器输出信号操控风机的旋转。
3. Combustion starting process: when the control system is on standby, it will enter the combustion operation state after receiving the input starting command. First, the control system will conduct self-test, then purge, and the inverter will output signal to control the rotation of the fan.
空气风量由低速渐变为高速再逐渐变为低速,新鲜空气吹过燃烧炉盘,以确保炉内没有残留燃气的存在,确保燃烧进程的牢靠。详细操作是变频器先起动。
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 and the combustion process is stable. The detailed operation is to start the inverter first.
PLC模拟输出信号使变频器频率从起动设定频率开端上升,到达频率后坚持时刻后再下降,完结起动前的吹扫。之后,宣布燃烧信号,高压燃烧器作业,同时翻开燃烧管道的阀门,小火点着。
PLC Analog output signal makes the frequency of the frequency converter rise from the start set frequency, and then drop after reaching the frequency, so as to finish the purging before starting. After that, the combustion signal is announced and the high-pressure burner operates. At the same time, the valve of the combustion pipe is opened and the small fire is ignited.
通过紫外线传感器的检测到期小火点着后,翻开主燃气阀门。这时催化燃烧炉盘进行有焰燃烧,直到检测温度信号到达设定的燃烧封闭温度,燃烧阀门封闭,完结燃烧进程,进入到催化燃烧调理阶段。
Through the detection of ultraviolet sensor, after the small fire is ignited, open the main gas valve. At this time, the catalytic combustion furnace plate carries out flame combustion until the detection temperature signal reaches the set combustion closing temperature, the combustion valve is closed, the combustion process is completed, and the catalytic combustion conditioning stage is entered.
