The function of gas distribution wall (GDW) is one of electrostatic precipitator parts. Gas distribution wall as shown in Figure 1 is a place for filtering dust from flue gas (product of combustion process in furnace steam boiler). GDW in principle operate without the use of electrical energy which consists of composition of iron plate made with holes.
Dust particle which is sucked by induced draft (ID) fan before entering electrostatic precipitator unit will pass through gas distribution wall (GDW), the level of dust particles that have bigger size than the size of holes will be stuck on the wall plate and fall down.
