Abstract
A direct heating device has a tubular main casing formed by a wall member. The main casing has a first end adapted to be coupled with a support structure, such as a monoblock fastening flange. One or more water inlets and out lets are provided in the wall member of the main casing. A funnel shaped sprinkler head is positioned inside the main casing. The bigger diameter end of the sprinkler head is coupled with the support structure. A critical nozzle in the shape of a long trumpet is coupled with the smaller diameter end of the sprinkler head. The direct heating device can also have a pressure relief damper, which has one end coupled to the main casing and the other end extending into the main casing. The main casing can have a double layer construction.
