要約:700 MW of utility boiler is investigated with manipulation of inlet burner angle. 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.
