PROCEDIMENTO ED IMPIANTO PER LA PREPARAZIONE DI GRANULARI A SFERET TIZZARE DA SOSTANZE INQUINANTI PRO VENIENTI DALLECENTRALI DI ENERGIA

摘要

Waste gas from a coal-fired power plant is scrubbed with a lime-water mixture to form a sludge whose water content is reduced and which is mixed with a binder such as water glass. This mixture is then pelletized to produce hard water-stable material suitable for use as an aggregate or filler. The waste gas may be stripped of its fly ash and this ash added to the sludge to thicken it.
