In order to increase thermal efficiency, while providing an economic and simple design, the double-wall structure is a pair of opposed hollow metal castings which bound not only the combustion chamber but also a combustion gas passage leading upwardly from that chamber and having in it projections integrally formed on the castings. Outside the castings are walls providing, in sequence, downward and upward passages for combustion gas and a downward passage for combustion air. | ||||||

The casing includes a plurality of radial webs cast on the casing and supporting a sleeve defining a combustion chamber for the combustion of fuel. A guide chamber and a collecting chamber are defined by the casing adjacent opposite ends of the sleeve, the guide chamber being arranged to receive the combustion gases from the combustion chamber and the webs defining therebetween flow ducts connecting the guide and collecting chambers for conducting the combustion gases to the collecting chamber. The casing extends beyond the two end walls of the housing and the end walls form a liquid-tight connection with the casing. The webs extend into the guide and collecting chambers, the height of the web portions in the guide and collecting chambers not exceeding that of the web portions supporting the sleeve. | ||||||

| 190 | Compact high-pressure steam generator | US49535074 | 1974-08-07 | US3915124A | 1975-10-28 | KUHN JR RALPH F; BATES JAMES O; CAMPBELL JR JOHN; RUSSELL LARRY H |
| A fast start-up compact high-pressure high-temperature steam generator is comprised of a multiplicity of individual fire tube boiler combustion devices housed in an enclosure. Each boiler assembly is supported by tube sheets and consists primarily of concentric inner and outer tubes. The inner tubes serve as a combustion chamber wherein a near stoichiometric mixture of fuel and oxidizer are burned. An annular chamber is formed between the inner and outer tubes and serves as a vehicle for water that is directed helically therethrough. Heat transfer through the walls of the inner tube convert said water from a liquid to a superheated steam for use with conventional steam turbine power plants or the like.

| 192 | Water heater and method of constructing the same | US79665569 | 1969-02-05 | US3802397A | 1974-04-09 | WARINER D |
| A small, inexpensive water heater is disclosed, of the type which uses an atmospheric burner to heat the water, together with a method for making the same from lightweight sheet metal material. According to the method, an elongated heater tube having open and closed ends thereon, is inserted into a liquid container having an opening in the wall thereof. The open end portion of the tube is connected to the wall of the container about the opening so that the opening is closed to the interior of the container while the bore of the tube is placed in communication with the exterior of the container therethrough. The closed end portion of the tube is extended below the operational level of liquid in the container so that the bore of the tube forms an elongated gas flow chamber for heating the liquid therein. Moreover, a baffle is mounted in the bore of the tube so as to separate the upper and lower portions of the chamber for a substantial distance along the length of the tube from the open end thereof. A fuel burner is interconnected with the lower portion of the chamber adjacent the open end portion of the tube so that hot gases can be fed along the bottom of the chamber in the direction of the closed end portion of the tube. A flue is interconnected with the open end portion of the tube adjacent the upper portion of the chamber so that the hot gases are withdrawn along the top of the chamber in the direction of the open end portion of the tube.
