摘要:
An apparatus for constantly supplying pulverized fuel at ambient or increased pressure includes a restrictable pulverized fuel control valve in the pulverized fuel feed line connecting the swirl layer of a dispensing vessel with a pulverized fuel collector is provided. This pulverized fuel control valve effects a compensation for and also attenuation of the pressure fluctuations, as occur in the pulverized fuel feed line, particularly during refill processes of the dispensing vessel. Special embodiments relate to a further homogenization by a fixed throttle facility and also auxiliary gas feeds into the pulverized fuel feed line.

A method for calibrating a dust load flow measuring system is provided. The dust delivery line may be connected from a metering vessel to a calibration line leading to the input sluice in the delivery direction downstream of the installed dust load flow measuring device instead of to the gasification reactor. The input sluice is provided with a weighing unit such that the weight of the content of the input sluice is determined. A differential pressure that may be set is controlled between the metering vessel and the input sluice, the dust load flow is determined in a time interval.

An entrained flow gasifier designed as a component for an Integrated Gasification Combined Cycle plant of optimized efficiency is provided. The raw gas initially flows through a waste heat unit designed as a radiation cooler and subsequently flows through a full water quench. This results in a higher ratio of steam in the raw gas, which decreases the medium-pressure steam supply before the water-gas shift and thus improves efficiency in IGCC plants with CO2 separation.

The invention discloses a method for producing an antenna system having at least one metal antenna unit and at least one carrier unit, wherein said antenna unit is connected in a first connection step to a heat-activated surface element, which can be glued, and the heat-activated surface element, which can be glued, is connected in a second connection step to the carrier unit, wherein the heating of said surface element in the second connection step occurs through said antenna unit. Furthermore, a surface element which is particularly suitable for this method and the products obtained therefrom are disclosed.
摘要:
A fly-stream gasification device for a process that employs powdery or liquid fuels—where liquid fuels are to be understood as oils, or oils containing solids, and water or oil suspensions containing fuels ground to the consistency of dust or inorganic additives—at pressures of between ambient pressure and 8 MPa and gasification temperatures of between 1,200 and 1,900° C., and which has a gasification means containing free oxygen, comprising a gasification chamber, a quenching device, and an element that belongs to the crude gas tract and ducts the crude gas, is embodied in such a way that an element ducting crude gas is made of heat-resistant carbon steel and furnished on surfaces in contact with the crude gas with an anti-stick layer able to withstand a temperature of 250° C. for preventing the carbonates that form from sticking.

A diaphragm pump is provided for the pressurized delivery of dusts in a dust feeding device. The diaphragm pump includes a storage hopper which is subjected to inert gas at ambient pressure and which serves for the storage of the dust. A sluicing vessel is provided which is connected via an inlet in the upper region, via a shut-off fitting and via a dust supply line to the dust store of the storage hopper, and is connected via an outlet in the lower region and via a shut-off fitting to a high-pressure device. A diaphragm is mounted in the sluicing vessel. An expansion line is provided, one end of which is connected via a filter element to the sluicing vessel and into which a shut-off fitting is incorporated. The diaphragm pump includes charging line which is connected via a filter element and via a shut-off fitting to the sluicing vessel.
摘要:
A device for the reliable measurement and control of the filling level in the quencher sump of a quenching chamber arranged downstream of the gasifying chamber is provided. The device has a differential-pressure transmitter. The measuring location recording the pressure of the gas chamber is flushed with inert gas. The device unproblematically senses the pressures in the quenching chamber and at the bottom of the quencher sump. The difference between which is used as a controlled variable for the filling level.
摘要:
Presented is a heat-activatedly bondable 2D element having a first adhesive and a second adhesive, which is suitable for bonding objects with a metal surface to objects with a plastic surface, and which enables a stable and mechanically robust bond even at low temperatures. This is achieved through the use of particular combinations of different adhesives, tailored to one another and based on synthetic nitrile rubbers and reactive resins.

A method for producing circuit boards, comprising a process for modifying a flexible circuit board, in particular for the stabilization thereof, characterized by at least the following method steps: a) providing a planar formation (“reinforcement plate”) having lower flexibility than that of the flexible circuit board, b) hot laminating an adhesive film, which can be activated by heat, on the reinforcement plate, c) placing the laminate made of adhesive film and reinforcement plate with the adhesive film side on the flexible circuit board, d) introducing the component made of reinforcement plate, adhesive film, and flexible circuit board into a partial vacuum atmosphere, e) hot laminating the component with application of pressure and heat.
摘要:
A method for producing electric energy from solid and liquid fuels is provided. The fuels are first subjected to a gasification process at high pressure, and the scrubbed gasification gas is fed to a gas and steam turbine process. The combustion of the scrubbed gasification gas in the gas turbine chamber does not occur with air, but with a mixture made of the three components oxygen, carbon dioxide and water vapor. As a result, the waste gas of the gas turbine is made only of carbon dioxide and water vapor. After the condensation thereof, technically pure carbon dioxide remains, which can be dissipated by storage in the deep substrate of the atmosphere.
