<p>An improvement in a radiation boiler for cooling a gas stream containing solid and molten particles wherein gas is introduced vertically via a gas feed at the top of a radiation boiler having a cooled gas outlet and a water bath disposed at the bottom thereof for removing the particles after they have been solidified and cooled. Between the gas feed and the water bath are disposed at least two concentrically arranged cylindrical tubular heat exchange elements vertically disposed in the boiler and forming at least one annular passage therebetween. The passage through the innermost heat exchange element is in fluid flow registry and fluid flow communication with the gas feed. A conical deflector has the axis thereof coincident with that of the innermost heat exchange element and thereby in registry with the flow of gas passing through the passage through the innermost heat exchange element and is disposed toward the bottom of the radiation boiler above the water bath but at least partially below the lower end of the innermost heat exchange element, whereby gas which strikes the conical surface of the conical deflector is deflected and passes through the at least one annular passage and in the passage of the innermost heat exchange element.</p> |
