1. A piping circuit for conveying particles comprising:
a first segment comprising an intersection where particles dispersed in a first gas combine with a second gas form a mixture, a cross sectional area inside the first segment strategically sized so that when the mixture flows through the first segment the particles are at a velocity at least as great as a pick up velocity of the particles, the intersection comprising a junction where a first pipe carrying the first gas and the particles joins directly with a second pipe carrying the second gas so that the first gas and particles are introduced directly into a flow of the second gas within the second pipe; and
a second segment comprising an upstream end in communication with the first segment, a terminal end distal from the upstream end, and a cross sectional area greater than the cross sectional area of the first segment and strategically sized so that when the mixture flows through the second segment the particles are at a velocity at least as great as a saltation velocity of the particles.
