✦ Synopsis

The trends towards using heavier fuel oil in the gas turbine engine will increase the soot formation rate in the primary zone, which increasesflame radiation and impairsflametubedurability.

Therefore, devising a method to determine quantitiatively the soot concentration is of paramount importance, as it helps in combustor design and pollution control. The method proposed adopts the Schmidt technique for radiation measurements together with soot formation and oxidation models. The soot concentration predictions from this method have been compared with thosecalculated from measurementsof radiation in the primary zone and exhaust smoke at the combustor exit. Favourable comparison was achieved, especially under full load conditions.
