摘要:
A method for stabilizing machine processes in which the machines are regulated by a machine regulation matrix selected from a plurality of machine regulation matrixes using a detected machine sensor value, set-point values of the machines being stored in each machine regulation matrix. A process is optimized according to a predefined criterion by also using some of the machine sensor values such that a machine regulation matrix which is optimal according to the process optimization is determined from the plurality of machine regulation matrixes and is subsequently used for regulating the machines.

The invention relates to a laser amplification system for generating retrievable laser pulses having at least one laser source, in particular with a pulse selector arranged downstream thereof for the targeted selection of amplifiable laser pulses, a laser medium for amplifying laser pulses generated by the laser source and a loss modulator, wherein the loss modulator is arranged and connected such that said modulator modulates the amplification of the laser pulses by the laser medium by loss generation so that the retrievable laser pulses are provided with a predefined pulse time and/or pulse energy. Before an amplification process for one of the laser pulses, the current amplification of the laser medium is determined and the loss generation is controlled by the loss modulator depending on the current amplification of the laser medium.

A combination gas-turbine and steam-turbine process and a power plant that utilizes the process. A waste-heat recovery system with a steam-circulation system is downstream and a pressurized furnace with a combustion chamber is upstream of a gas turbine. Flue surfaces that heat air are accommodated in the furnace. A pressurized gasifier parallels the furnace. Flue gas from the furnace, preheated combustion air, and combustion gas from the gasifier are forwarded to the combustion chamber. The heat of combustion liberated in the furnace by heating the flue gas to beyond its combustion temperature is transmitted exclusively to the combustion air being forwarded to the combustion chamber.

A device for varying the height of a bed in a fluidized combustion chamber inside a pressurized housing. Bed material is supplied to the chamber from hoppers or returned back to the hoppers from the chamber through a supply line. The supply line connects the chamber and the hoppers. The hoppers have means of increasing or decreasing the pressure. To improve the means of both increasing and decreasing pressure in the known device and of cleaning the gas that enters into contact with the material in the hopper, each hopper contains a hot-gas filter that gas can flow through in two directions and each hopper communicates above the filter with a gas connection that can be maintained at either a higher or a lower pressure than the fluidized combustion chamber.

The invention relates to a mirror arrangement for guiding a laser beam in a laser system having at least one first end mirror and one second end mirror, wherein said end mirrors define a resonator having an optical resonator axis, wherein the laser beam is guided into the resonator as an input laser beam and is guided out of the resonator again after multiple reflection at the first and second end mirrors as an output laser beam. The sequence of reflections at the first and second end mirror thereby determines a direction of rotation between the first and second end mirror, defined as an axis of rotation relative to the resonator axis, whereby a first beam path is defined and the laser beam circulates in a direction of rotation between the first and second end mirrors in the resonator defined as an axis of rotation relative to the resonator axis. The resonator is designed such that the direction of rotation is reversed at a reversing point and the laser beam in the resonator passes through at least partially in a direction of rotation opposite to the first beam path, whereby a second beam path is defined.

摘要:
A device for filtering hot, dust-laden gases with filter tubes (2) accommodated in a closed housing (1) that contains both a dirty-gas section and a clean-gas section and consisting of hollow structures (9) that have at least one exit that communicates with the clean-gas section and are otherwise closed, characterized in that the edge (11) around the exit from each tube constitutes a base and rests subject to the weight of the tube against a counterpart in the clean-gas section such that the weight of the tube and the difference between the pressure of the gas in the dirty-gas section and that of the gas in the clean-gas section act parallel.
