| The device called the flow enhancer can be used to improve capacity in long distance pneumatic conveying systems. A technique has been developed to determine how the maximum capacity of a system is affected by inserting a flow enhancer in a system. This work shows that the capacity of a system can be increased between 3.5% and 38% depending on the system, particles, and degree of original optimization of a pneumatic conveying system.;A pneumatic conveying system can be extremely violent and erratic when conveying in the unstable zone. Identification of where this area begins would, therefore, be useful to operators wishing to stay clear of this zone. A procedure for the identification of the start of this area from the dilute phase conveying side has been tested. The starting point of the unstable zone is shown to follow an exponential function on a typical state diagram. This technique should also prove useful in conjunction with the flow enhancer by showing the operator the absolute maximum amount of air that can be removed from a pneumatic conveying line. |
