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.

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.

A burner head of ceramic materials through which the fuel (combustible) and the oxidizing agent (oxygen or oxygen-containing gas such as air) are passed from an inlet side to an outlet side, combustion being effected at the outlet side. According to the invention, the gas passages for the fuel and the oxidizing medium are of elongated cross section and parallel to one another, being offset in pairs so that indirect heat exchange is effected between the two mediums through the separating ceramic wall. The passages can be formed as rectangular-section channels which are closed at the top and bottom by ceramic plates.

A burner system in which an ignitable mixture is formed from vaporized liquid fuel and preheated air which is heated by recuperative heat exchange with a furnace exhaust gas from the combustion chamber in which the mixture burns. According to the invention, a feed line for the fuel opens into a closed chamber provided with porous walls permeable to the fuel and with a flow passage traversed by the preheated air, the wall of this flow passage in turn serving for indirect heat exchange of the air by the combustion gases of the furnace.
摘要:
A ceramic recuperator for the heating of combustion air, e.g. for an oil-fired burner or boiler, which prepares at least the air in the formation of a fuel-air mixture which is ignitable at the burner. According to the invention the recuperator is provided with means, especially electrically operated for heating the ceramic body so that the initial combustion air can be heated before firing of the burner and the further heating of the recuperator by combustion products.

A nuclear power-generating installation comprises three power-generating bines which are operated by three partial gas streams heated in separate passages of a nuclear reactor. After traversing the power-generating turbines the partial gas streams are cooled in respective recuperative heat exchangers to recover residual useful heat therefrom and are combined into a lesser number of gas streams each of which is subjected to at least two compression stages with at least one intervening cooling stage in which all of the gas is combined to flow as a total gas stream through at least one such cooler. Following the last compression stage the gas is again subdivided into three partial streams for preheating in the aforementioned recuperative heat exchangers before traversing the nuclear reactor for the main heating.
摘要:
A process and an arrangement for the formation of an ignitable mixture fromiquid 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.
