“…The impact of the electric load on qr and Tf″ was shown under condition 2 where the load was relatively stable but was also slowly changing. In fact, the general trends of qr and Tf″ were consistent with the load [13,40], which could also be observed under condition 2. It was noteworthy that qr increased during the soot-blowing period which was opposite to the trend of the load, implying the apparent improvement of the heat transfer performance.…”
