Further descriptions are given in the Iron and Steel BREF\nOnly applicable if basic oxygen furnace gas is combusted\nd.\nElectrostatic precipitator (ESP)\nSee descriptions in Section 8.5\nOnly applicable to combustion plants combusting a significant proportion of auxiliary fuels with a high ash content\ne.\nBag filter\nTable 31\nBAT-associated emission levels (BAT-AELs) for dust emissions to air from the combustion of 100 % iron and steel process gases\nFor existing plants operated < 1 500 h/yr, these BAT-AELs do not apply.\nFor existing plants operated < 500 h/yr, these levels are indicative\nType of combustion plant\nBAT-AELs for dust (mg/Nm3)\nYearly average\nDaily average or average over the sampling period\nNew or existing boiler\n2–7\n2–10\nNew or existing CCGT\n2–5\n2–5",
