Manipulation of burner titling angle is an operational methodology in controlling rear pass temperature in utility boilers. The rear pass temperature unbalance between right and left side is a problem caused by fouling and slagging of the ash from the coal fired boilers. This paper presents the CFD investigation on the 0� and -30� of the burner angle of the utility boiler. The results focusing on the velocity profile. The design condition of 0� burner firing angle is compared with the off-design burner angle -30� which would be the burner angle to reduce the rear pass temperature un-balance by boiler operators. It can be concluded that the -30� burner angle reduce the turbulence is fire ball mixing inside the furnace. It also shift the fire ball position in the furnace to reduce the rear pass temperature.
