Abstract:
1. A continuous dense phase pneumatic conveying system for transporting particulate material through a conveyance line with a transport fluid, said pneumatic conveying system comprising: a conveyance line; a particulate material insertion assembly configured to insert particulate material from a particulate material supply into the conveyance line; a positive displacement blower disposed upstream of the particulate material insertion assembly, said blower configured to feed transport fluid through the conveyance line to transport the particulate material; a transport fluid intake assembly disposed upstream of the blower, said transport fluid intake assembly configured to provide transport fluid from a transport fluid supply into the blower through a transport fluid supply line; and a mechanically controlled vacuum throttling assembly disposed upstream of the blower, a portion of said vacuum throttling assembly being in fluid communication with the transport fluid pressure downstream of the blower, said vacuum throttling assembly configured to vary the flow of the transport fluid into the blower depending on the transport fluid pressure downstream of the blower.
