Existing correlations are reviewed for heat transfer of high finned tubes in staggered arrangement, and compared with published experimental data. These data include those using tubes for air coolers (AC) and for heat recovery heat exchangers in the high temperature region (HRHX). Comparisons showed that none of the correlations can predict experimental data for both AC and for HRHX. Therefore, a new correlation is proposed which can predict almost all data within 10 %.
