| 摘要 |
The present invention provides a process and a device for transport of gas in a main duct with more than two branch ducts wherein the gas is guided through the branch ducts (1, 2, 3, 4, 5, 6, 7, 8) and into the main duct (A) with a direction which is parallel to the direction of the flow in the main duct, while the gas in the branch duct at the inlet to the main duct is kept at a higher velocity than the gas in the main duct and the gas in the main duct is given an impulse, by utilisation of excess energy from the gas in the branch duct, for acceleration of the gas prior to introduction into the main duct.
