Boiler or vapor generator using catalytic combustion of hydrocarbons

摘要: A boiler or vapor generator using catalytic combustion of hydrocarbons to evaporate a fluid passed through pipes operates in accordance with the principles U.S. Pat. Nos. 3,908,602 and 3,952,707 comprises vertically disposed catalyst elements within thermally insulated housing. The space between elements, which face one another, is occupied by pair coiled tubes are superposed so as be imbricated another. tube coils shield from radiation interchange heat. two connected lower supply an upper collector traversed liquid vaporized heated form wall without interstices panels.
