And the combustion chamber temperature control operates as follows:
when a power switch of the incinerator is turned on, a fan in the incinerator starts to work, the incinerator is automatically ignited after about 10 seconds, at the moment, a temperature controller displays vertically, the uppermost row displays a temperature value, the second row displays a set temperature value, the '▲' on the panel in the lowermost row is set to be pressed to increase a numerical value, and the 'xxx' is used for reducing the numerical value.
The concentrations of the parameters show: the experimental device (i.e. aerobic composting device and waste incineration device) is provided with an online monitoring system (i.e. monitor and sensor), and the online monitoring system can be used for monitoring the concentration of relevant parameters in real time and the like.
Excess air factor adjustment: the opening of the outlet valve is adjusted by starting the oxygen increasing fan, and the air coefficient value is adjusted.
