According to the lab chemical ignition principle, place the collected unburnt carbon sample in a specified high temperature environment for burning, because the combustible materials in the fly ash are oxidized at high temperature, the sample mass losses, the carbon content value of the fly ash sample can be calculated according to the loss of the ash sample
The system collects the fly ash in the flue automatically by the self-sampling device, and sends the ash sample to high temperature resistant container and weighs automatically, hen actuator in the measuring unit sends this container to electric heater for high temperature burning;at and of the burning,the device weighs the container again,and calculates fly ash carbon content value by this device according to the reduced amount of the ash sample. The ash sample after burning returns to the flue through the system ash discharge device.
