Abstract: A rotor blade for a wind power station includes a profiled member that is provided with a relative thickness which decreases towards the outside from a root to a tip of the blade. The profiled member has a leading edge and a trailing edge as well as a suction side and a pressure side while generating a negative pressure relative to the pressure side on the suction side when being flown against by moved air, the negative pressure resulting in buoyancy. The suction side of the rotor blade encompasses a device for optimizing flow around the profiled member. The device is provided with at least one planar element that extends substantially in the direction of flow, protrudes from the suction side, and is arranged in the zone of a transversal flow which runs from the root to the tip of the blade on the suction side of the profiled member.

Abstract: 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.

Abstract: 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.

Abstract: 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.
