Abstract: The invention relates to a method for operation of a burner, whereby a mixture used for burning is supplied to the burner in a two-stage process. In a first step atomised water is mixed with combustion air and said mixture is mixed with a fuel in a second step and then supplied to the burner. Said burner comprises means for carrying out the above method.

Abstract: Disclosed is a gas and steam turbine plant comprising a cooling system which is configured such that said cooling system is suitable for each operational state and cools cooling air that is bled from the compressed air, and a heat exchanger system which is mounted on the primary side of a cooling air duct that branches off the compressed air duct. Said heat exchanger system transmits heat that is transported in the cooling air to a flow of combustible gas which is fed to the combustion chamber of the gas turbine.

Abstract: In order to prevent the increase of NOx due to an excessively high combustion temperature and the increase of HC and CO due to an excessively low combustion temperature, by feeding an emulsion of a fuel oil and water having a water content suitable for the combustion state in cylinders to a Diese engine, there is proposed: A combustion parameter sensor (3) for detecting combustion parameters inside cylinders such as an internal pressure of the cylinder, an engine knock, an exhaust gas, etc. and a water charging quantity judgement/regulation circuit (2) for setting a water charging quantity to a fuel are disposed in a Diesel engine (1). A water charging quantity controller (4) feeds water to an emulsion formation apparatus (5) in a quantity corresponding to a water charging signal from the water charging quantity judgement/regulation circuit (2).

Abstract: Method and apparatus for producing a water-in-fuel-emulsion and emulsifier-free water-in-fuel-emulsion. The apparatus for generating a fuel water emulsion for the operation of an injection pump, particularly that of a diesel motor, comprising a rotationally symmetric vortex chamber (1) with a tangential inlet and a tapering axial outlet. In order to generate a fine homogeneous emulsion in colloidal state, having a size of the suspended water droplets of 1000 nm or less, the axial end portion of the vortex chamber (1) facing away from the outlet is surrounded by a ring channel (7) running coaxially to the vortex chamber (1), the ring channel (7) being connected to the vortex chamber (1) via inlet slots (9) which are tangentially aligned to it and in which a fuel inlet channel (8) tangentially ends. An electromagnetically controlled water injection nozzle (10) leads into the end portion of the vortex chamber (1) at the inlet side thereof.
