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.
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.
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.
Catalytic combustion equipment
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.
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.
