Critical Heat Flux (CHF) in a non-uniformly heated tube under inclined upward flow conditions is very important factor in designing actual boiling systems. However, only a few investigations on the CHF have been conducted under these conditions. Consequently, in the series of investigations, the experimental study on the CHF of non-uniformly heated tube was conducted with 900 mm and 1800 mm in heated length under the inclined condition. In this study, the CHF experiment was conducted with 450 mm in heated length under several inclination angles, i.e. 15, 30, 45 and 90 degree. The characteristic of CHF is decided by the relation between the gravity and the liquid film lift up, and these effects have been able to be categorized by using the modified Froude number well.
