Abstract

Coal is one of the energy sources that widely used for electricity. Nonetheless, the high demand for coal is not comparable with the remaining coal in the world, so it is necessary to make a study to reduce the consumption rate of coal. Increase the efficiency of the tangentially fired boiler with improvement in the burner is one of the right options. In some cases, because of the uneven distribution of coal type, blended of mixing coal of higher and lower rank coal is necessary. This condition will affect the combustion behavior in the boiler, also emission production. This research will study the effect of yaw angle modification to combustion behavior and emission analysis in the tangentially-fired boiler with the condition of fuel 30% MRC and 70% LRC. Computational fluid dynamics has been used in this study with validation. The yaw angle diverse from +5º, 0º, -5º, -10º, dan -15º. The results show that the wider yaw angle increases the temperature deviation and NOx concentration. Coal burner with -5º has the least temperature deviation and the lowest NOx emission, which has 83,07 ppm of NOx, then -5º yaw angle is chosen.
