Material flow amplifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion and head losses) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile (e.g., increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like).

An object of the present invention is to provide a technique in which deposition of powder during pneumatic transport can be inhibited by a pipe body having a simple structure. The present invention is a pipe for transporting powder including a transport path which has a portion formed by a curved pipe and through which pneumatically transported powder passes, and a blowing path through which a gas is blown into the transport path from an opening formed on an inner circumferential surface of the curved pipe, in which the blowing path blows the gas in a direction in which the gas blown into the transport path from the opening forms a swirling flow along the inner circumferential surface of the curved pipe.

A transportable and combustible gaseous suspension includes solid fuel particles suspended in a gaseous carrier. The solid fuel particles have a sufficiently small particle size so that they remain suspended during transportation. The gaseous carrier may include reactive and inert gases. The solid fuel particles may include coal-derived solid carbonaceous matter. Other examples of solid fuel particles include biomass, refined bioproducts, and combustible polymer particles. The combustible gaseous suspension can be tailored to have an energy density at atmospheric pressure which is comparable to conventional gaseous hydrocarbon fuels. The gaseous combustible fuel may be pressurized to a pressure in the range from 2 to 100 atmospheres.

Method for compensating a change in volume caused by a pressure difference of the intermediate container of an input point of a pneumatic pipe collection system for material and/or for preventing undesired material displacement from the intermediate container. In the method a bypass channel is arranged in the channel section formed by the intermediate container of an input point for compensating a change in volume resulting from the pressure difference of the pressures of different magnitudes possibly acting on different sides of the material and/or for preventing undesired material displacement from the channel section into the material conveying pipe. The invention also relates to an apparatus and to a wastes conveying system.

In one aspect, a system for removing blockages present within a delivery conduit of a seeder may include a plurality of delivery conduits, a plurality of flow blocking devices, and a plurality of blockage sensors. A controller may be configured to determine when a blockage is present within a first delivery conduit of the plurality of delivery conduits based on measurement signals received from the plurality of blockage sensors. The controller may be further configured to control the flow blocking devices to occlude the flow of air through the other delivery conduits of the plurality of delivery conduits such that an air pressure in the first delivery conduit is increased.
