Vee manifold with at least three flow channels

A manifold for a first substance and a second substance to travel therethrough, the manifold comprising:

• a block having an inlet portion and an exit portion, the exit portion comprising a connection portion defining a connection portion longitudinal axis, wherein a first portion of the block defines an air inlet port;
• a first channel extending through the connection portion, the first channel defining a first channel longitudinal axis;
• a second channel extending through the connection portion, the second channel defining a second channel longitudinal axis;
• a third channel extending through the connection portion, the third channel defining a third channel longitudinal axis, wherein the third channel is in fluid communication with the air inlet port;
• and
• a fourth channel extending through the connection portion, the fourth channel defining a fourth channel longitudinal axis,
• wherein the first channel within the connection portion is oblique to the connection portion longitudinal axis, wherein the second channel within the connection portion is oblique to the connection portion longitudinal axis, wherein the third channel within the connection portion is oblique to the first channel and the second channel, and wherein the fourth channel within the connection portion is oblique to the first channel and the second channel, and
• wherein the first channel is configured to receive the first substance, wherein the second channel is configured to receive the second substance, and wherein the third channel is configured to receive a flow of air.

An exit portion of a manifold configured for a first substance and a second substance to travel therethrough, the exit portion comprising:

• a connection portion defining a connection portion longitudinal axis;
• a first channel extending through the connection portion, the first channel defining a first channel longitudinal axis;
• a second channel extending through the connection portion, the second channel defining a second channel longitudinal axis;
• and
• a third channel extending through the connection portion, the third channel defining a third channel longitudinal axis;
• and
• a fourth channel extending through the connection portion, the fourth channel defining a fourth channel longitudinal axis,
• wherein the first channel within the connection portion is parallel to the connection portion longitudinal axis, wherein the second channel within the connection portion is parallel to the connection portion longitudinal axis, wherein the third channel within the connection portion is parallel to the connection portion longitudinal axis, and wherein the fourth channel within the connection portion is parallel to the first channel and the second channel, and
• wherein the first channel is configured to receive the first substance, wherein the second channel is configured to receive the second substance, and wherein the third channel is configured to receive a flow of air.

In combination:

• an exit portion of a manifold configured for a first substance and a second substance to travel therethrough, the exit portion comprising:
• a connection portion defining a connection portion longitudinal axis;
• a first channel extending through the connection portion, the first channel defining a first channel longitudinal axis;
• and
• a second channel extending through the connection portion, the second channel defining a second channel longitudinal axis;
• and
• an insert removably connectable to the second channel, the insert defining an insert channel, wherein a diameter of the insert channel is less than a diameter of the second channel, wherein with the insert connected to the second channel, an outlet of the insert channel is located closer to the connection portion longitudinal axis than a first channel outlet of the first channel and a second channel outlet of the second channel.
