Film evaporating combustion chamber

A film-evaporating combustion chamber comprising an evaporator pipe means, guide wheel means operable to produce a swirl of the combustion air and operatively connected ahead of an inlet opening of the evaporator pipe means, and tubularly shaped air guide housing means for guiding combustion air from the outside in a substantially axial direction, the air guide housing means enclosing the evaporator pipe means and an adjoining reaction chamber means, characterized in that a radial guide cascade means having blade channel means is provided as guide wheel means, deflection means are arranged inside of the air guide housing means for supplying the substantially axially entering combustion air to the radial guide cascade means, the combustion air being deflected substantially in the axial direction after leaving the blade channel means of the radial guide cascade means, an inner contour of the deflection means runs out essentially in a direction toward an axis of the guide wheel means, outer walls of the blade channel means are substantially aligned at an outlet side thereof with wall means of the evaporator pipe means, said evaporator pipe means being enlarged substantially conically from the radial guide cascade means with an end of the evaporator pipe means opposite the radial guide cascade means projecting freely into the reaction chamber means which has a substantially larger diameter, wall means of the reaction chamber means are extended up to the inlet side of the blade channel means of the guide cascade means so as to define an annular space surrounding the evaporator pipe means between the evaporator pipe means and the reaction chamber means, an ejector ring means is inserted into the annular space, inlet opening means are provided for communicating the annular space with an air inlet space enclosed by the deflection means, the annular space is provided with an essentially circularly shaped discharge slot means directed approximately parallel to an outer wall of the reaction chamber means, and in that the discharge slot means is arranged along an outer circumference of the ejector ring means and is open in a direction toward the radial guide cascade means.
