A ceramic heat transfer device with a heat transfer matrix. The matrix includes gas ducts and fluid ducts which are arranged close to and parallel to each other. Inlet and outlet openings are provided in the boundary wall of the hear transfer matrix to facilitate the inlet and outlet of material. Fluid inlet and outlet slots are provided on both sides of the heat transfer matrix and boundary walls cover guide pockets. This arrangement allows the medium connections to be independent of the dimensions of the heat transfer matrix and provides for guidance of the medium, or material. the ends of the enlarged area of the guide pockets that connect the openings are arranged so that connection nipples are provided for connecting fluid pipes. Gas and fluid webs are provided in slot-like gas and liquid conduits for guidance of gas and fluid.

Ceramic heat exchanger

An internal combustion engine having combustion chambers with ceramic linings. These ceramic linings have webs between inner and outer surfaces for forming sealed cavities therein.

Combustion space with a ceramic lining such as in the combustion chamber

Liquid fuel and water pressurized by fuel and water pumps are forced into a aporizer which is heated by hot exhaust gases of a piston engine. The resulting vapor mixture is blown into the combustion chamber of a cylinder head of the engine at a speed up to that of sound near the end of the engine's compression stroke where it mixed with precompressed air. The resulting explosive mixture is ignited by self-ignition or by spark plug and the water vapor content mixed with the fuel vapor lowers the combustion temperature, resulting in a significant reduction of nitrogen oxide content in the exhaust gases. The ratio of water vapor to fuel vapor is preferably 1:1 to 3:1 and the temperature at which the vapor mixture is introduced into the cylinder is above the dew point of the fuel in the fuel vapor and water vapor mixture. The mixture of fuel with air is approximately stoichiometric. Diesel oil is useable, and also such bio-mass fuels as vegetable oils.

Method and cylinder head structure for supply of fuel into a piston

A process and an arrangement for the formation of an ignitable mixture from iquid fuel and combustion air, wherein preheated combustion air is conducted with a flow chamber along a surface which is moistened with fuel for take-up of fuel. In the process and arrangement, combustion air is conveyed into the flow chamber in the flow direction of the fuel which streams off the surface moistened by the fuel under the effect of gravity. Achieved hereby is an intensive contacting between the combustion air and the fuel. The fuel is dosed in excess so as to constantly afford a sufficient quantity of fuel for vaporization. During the through flow of the combustion air, there is formed, in the contact with the fuel, a saturated fuel-air mixture in conformance with the temperature of the preheated combustion air and the temperature of the fuel. Concurrently, care is taken that the trickling film of the fuel which is formed by gravitation as well as the drag effect exerted by the combustion air passing through the flow chamber can freely exit from the flow chamber at the foot of the surface moistened by fuel, to the extent in which the fuel is not taken up through vaporation by the combustion air in the flow chamber.

A heating system for supplying utility water and a heating fluid for space heating purposes comprises a unit fired by a burner and having a recuperator traversed by the combustion gases and forming a first zone for heating the space-heating fluid and a second zone for heating the utility water. According to the invention, a heat exchanger is provided along the path of the utility water delivered from the second zone to a reserve tank and the heat exchanger is connected in a bypass across the feed and return lines of the heating fluid circulating path. A control responsive to the temperature in the tank regulates the flow through the bypass while a further temperature control responsive to the feed side temperature of the space-heating circulation path controls the fuel supplied to the burner and the rate of combustion gas flow through the heat exchanger.

Space and utility water heating system

A fluid-heating apparatus comprises a ceramic burner head formed with narrow passages which alternate with one another for fuel and a combustion sustaining medium such as air, the slit-like passages opening into a combustion chamber at which combustion of the fuel/air mixture occurs. Downstream of this combustion chamber is a ceramic recuperator likewise formed with slit-like passages, the hot combustion gases traversing some of these recuperator passages while the fluid medium to be heated is passed through others of these passages so that heat exchange is effected through the thin ceramic walls supporting the slit-like passages of the ceramic recuperator.

Fluid-heating apparatus

Burners operating with combustion air as the combustion-sustaining gas and a fuel, generally a vaporizable liquid fuel, have at least one ceramic body formed with passages for these two fluids allowing heat exchange through the walls separating these passages. According to the invention, these walls are porous so that fuel in the fuel passage can traverse the wall into an adjoining air passage by evaporization on the surface. The combustion air can be heated by recuperative heat exchange from exhaust gases of the combustion chamber. Burner heads of this type can be paired in mirror-symmetrical relationship.

Burner assembly with parallel passages for fuel and oxidizing gas

A filter for the removal by the exchange effect of fission products from the coolant, generally helium, of a nuclear reactor comprises a gas-tight duct containing at least one coil of corrugated metal strip, the coil being formed from two strip layers whose corrugations are mutually crossing.

A core energy plant with closed working gas circuit, in which within an or safety container there are arranged a reactor core of pre-stressed concrete for heating the working gas, a working gas driven turbo-set with generator, and other components of the working gas circuit such as heat exchanger and gas storage means. The reactor core is separated from the turbo-set and other components and is arranged in a separate reactor chamber with walls of pre-stressed concrete, while the other components are respectively arranged in separate chambers, within an inner concrete container which has chambers for receiving the turbo-set with generator and the remaining components of the working gas circuit and which has its outer wall arranged adjacent the vertical inner wall of the outer safety container there is provided a recess for a pre-stressed concrete container for receiving the reactor core.

Core energy plant with closed working gas circuit

A nuclear energy plant with a closed circuit for the working gas, in which nuclear reactor operable to heat up the working gas, is through a plurality of gas conduits arranged in parallel, connected to a plurality of turbo-sets for generating electric energy and to circuit components following the turbo-sets. One turbo-set each and the respective circuit components associated therewith are respectively arranged in common structural units which are radially arranged around the nuclear reactor. Each of the structural units comprises a first connection for a hot gas conduit withdrawing the heated working gas from the reactor and a second connection for a cold gas conduit for conveying the working gas to the nuclear reactor after the working gas has passed through the respective circuit components.
