Patent ID: 6994527

Claim:
A process for transport of gas in a main duct with more than two branch ducts, each one of the more than two branch ducts having a nozzle, wherein a) the gas is brought through the more than two branch ducts and from the more than two branch ducts into the main duct in a flow direction parallel to the flow direction of the gas in the main duct; b) the gas in each one of the more than two branch ducts is, at the inlet to the main duct from the more than two branch ducts, kept at a higher velocity than the gas in the main duct; c) the gas in the main duct is given an impulse by utilization of excess energy from the gas in each one of the more than two branch ducts for acceleration of the gas from each one of the more than two branch ducts prior to the introduction of the gas from each one of the more than two branch ducts into the main duct; and d) the gas velocity in each one of the more than two branch ducts is adjustable by adjusting the position of a flap in the nozzle in each one of the more than two branch ducts.
