Abstract
A trunnion bolt monitoring system for an air preheater trunnion has a plurality of trunnion bolts through which extends a respective blind bore each in gas tight connection at its open end to a pressurized manifold comprising piping and T-fittings. Depressurisation of the manifold indicative of fatigue cracking of any one bolt is detected by electrical monitoring of three pressure sensors.
