In the case of a boiler device equipped with FDF and AH for each
The passing air flow rate of H can be grasped as the flow rate of air supplied from each FDF, and when the passing air flow rate of each AH is equal, if the degree of clogging due to ash adhesion to each AH element is different, each AH Since the pressure difference between the air and gas inlet / outlet ports differs from that in FIG.
If detected by the H gas side differential pressure detector 10, it can be specified that AH having the highest differential pressure has the largest amount of clogging due to ash adhesion.

Connect to The AH air outlet ducts merge after leaving each AH. For this reason, even if the degree of clogging of the AHs is different, the ratio of the air flow passing through each AH is changed to be in a balanced state, and the inlet / outlet pressure difference of each AH becomes the same value, and the pressure difference Cannot detect clogging.

握しにくい。When the degree of clogging of the AH element is high, the air flow rate and the gas flow rate are similarly low, but the heat exchange amount at the AH is low. There is almost no apparent change depending on the degree. Therefore, it is difficult to grasp the degree of AH clogging from the temperature characteristics.
