1.Review of Electric Heating Tube Power
By measuring the end resistance of the heating tube, the power of each heating tube can be calculated, allowing for a review of the electric heating tube power.
2.Review of Surface Heat Load of Electric Heating Tube
According to W=P/S, calculate the heating area S, and then W can be determined to verify the load of the electric heating tube, thereby monitoring the service life of the heating element.
Where: P------heating power of each electric heating tube, W;
S------heating area of each electric heating tube, cm²;
W-----surface heat load (power density) of each electric heating tube, W/cm².
