Boiler Slagging - Babcock Power

helpful in preventing slag and are well-known to all power plant operators: EXCESS AIR Increased excess air reduces the furnace tempera- ture for any given Btu input (fuel feed rate or steam load). High excess air usually reduces carbon loss and shortens flame length. All of these are hel pful in preventing slag problems, but increased excess air

Power Station Slag Recycling - Dirk Group

The solution: The molten and then crystallized slag is washed out of the power station into a slag pond. The wet ash is extracted from the pond and left in the open to loose most of the quenching water. Thereafter the slag is dried in a rotating dryer to dry and de-agglomerate bigger particles before screening in to five different particle sizes.
