Abstract
A boiler or vapor generator using catalytic combustion of hydrocarbons to evaporate a fluid passed through pipes operates in accordance with the principles of U.S. Pat. Nos. 3,908,602 and 3,952,707 and comprises vertically disposed catalyst elements within a thermally insulated housing. The space between the catalyst elements, which face one another, is occupied by a pair of coiled tubes which are superposed so as to be imbricated in one another. The tube coils shield the catalyst elements from radiation interchange of heat. The two coiled tubes are connected with a lower supply tube and an upper collector and are traversed by the liquid to be vaporized and heated so as to form a wall without interstices between the catalyst panels.
Claims12
A boiler or steam generator comprising:
- a thermally insulated housing;
- at least one pair of vertically disposed spacedly juxtaposed catalyst elements received in said housing for catalytic combustion of a fuel to produce heat;
- a pair of imbricated tube coils having vertical axes and disposed between but spaced from said elements and forming a radiation shield between them preventing direct radiation of one of said elements onto another;
- means for feeding a liquid to be heated to said coils at the bottom of said housing;
- and
- a collector for heated fluid communicating with said coils at the top thereof.
