Abstract
A powder spraying system comprises a source of dry powder (), a spray nozzle (), and a supply conduit () connecting the source of dry powder with the spray nozzle. The spray nozzle comprises a nozzle body () having a nozzle outlet (), a first conduit () for dry powder, and a second conduit () for gas. The first conduit extends between a powder inlet () in communication with the supply conduit and a powder outlet (). The second conduit extends between a gas inlet () and a gas outlet (), the gas outlet being located in proximity to the powder outlet such that a gas flowing through the second conduit and out of the gas outlet produces a suction force at the powder outlet to promote flow of a dry powder through the first conduit and out of the powder outlet and the nozzle outlet. The powder outlet and the gas outlet are orientated to promote mixing of the gas with the dry powder. The first conduit () is a straight conduit between the powder inlet () and the powder outlet ().
