Abstract
In accordance with one aspect of the invention, a venturi having a heat shield along its inner diameter and a thermal barrier coating along its outer diameter is provided, whereby the temperature gradient of the venturi is lowered and metal distress and erosion caused by water injected therethrough is reduced. In an alternate embodiment, a floating insert is placed within an area along the venturi's inner diameter, where it is held in position by a heat shield.
