ABSTRACT:
An improved pneumatic lime dispensing and conveying system of the type comprising a lime storage container having a dust collector communicating with the storage container for removing dust from the air inside the container and venting the filtered air from the storage container, and a pneumatic conveying system having an air inlet for pneumatically conveying lime dispensed from the storage container through a conveying line. The outlet vent of the dust collector is connected to the air inlet of the pneumatic conveying system to reduce CO.sub.2 content of the air, and thereby inhibit scale formation in conveying line. The method of this invention comprises the step of pretreating the air used in the conveying system by exposing it to lime dust to reduce the CO.sub.2 content of the air. This is conveniently carried out by drawing the air through a dust filter connected to the lime storage container.
