Abstract
A fluid injector for injecting an injection fluid into a hot flow can include a flow structure defining an injection flow channel and configured to extend at least partially into a flow path to introduce the injection fluid into the hot flow in the flow path. The flow structure can include one or more heat resistance features to protect the flow structure and the fluid from heat of the hot flow.
