Kwizityalo zamandla, ukunciphisa ubushushu be-flue ngokwendlela yenkqubo kuya kubangela ukuba i-flue ifakwe kwi-acid. Common hazards include dust blockage, corrosion, and air leakage.

Umzekelo:

Air preheaters, because the wall temperature is below the acid dew point, cause severe corrosion. Jonga umfanekiso 01.

Heat exchangers made of ND corrosion-resistant steel have severe corrosion in less than a year because the wall temperature is lower than the acid dew point.
