摘要:
A method and device for the gasification of solid fuels such as bituminous coals, and cokes such as those from bituminous coals, lignite coals, and biomasses, as well as petroleum cokes, that are ground fine and mixed with water or oil to obtain fuel-in-liquid suspensions, so-called slurries, and their gasification together with an oxidizing medium containing free oxygen, by partial oxidation at pressures between atmospheric pressure and 100 bar, and at temperatures between 1200 and 1900° C. in an entrained flow reactor. The method includes slurry preparation and infeed to the reactor, gasification in an entrained flow reactor with cooled reaction chamber contour, full quenching of the crude gas to saturation temperature that may be 180-260° C. depending on the gasification pressure, and wet or dry dust separation. The crude gas is pretreated so that it can be fed to further technological steps such as crude gas conversion, H2S and CO2 removal, and synthesis.

The invention is directed to an arrangement for making contactless distance measurements within an air spring of a motor vehicle. With the invention, it is unnecessary to modify the longitudinal support of the motor vehicle for the purpose of integrating an ultrasonic distance measuring device. The arrangement includes a transmitter/receiver component (16) which is fixedly mounted to the chassis and is mounted within the air spring (2) laterally next to the support (10) of the vehicle, that is, the transmitter/receiver component is mounted elastically off-center in a tubular stub (14) arranged as part of the cover plate (4). A reflector component (24) is fixedly mounted on the axle and assigned to the transmitter/receiver component (16). The reflector component (24) is mounted on the roll-off piston (8) and includes a lens-shaped convex surface (26) having a surface normal (28) directed toward the transmitter/receiver component (16).

摘要:
A pressure filtration system for cleaning residual quenching water of a gasifying device that gasifies carbon-containing fuels under elevated pressure is provided. The soot water from the quencher is passed to a filter system, which has pressure filter chambers operating alternately in filtering mode under gasifying pressure or in cleaning mode. The filtrate from these chambers is passed to a quenching water reservoir, from which the quencher is fed with quenching water. Only small temperature and pressure losses with respect to the residual quenching water leaving, and only a small additional amount of energy has to be expended to overcome the remaining pressure difference to bring the filtrate that is to be returned back to the gasifying pressure. The residual quenching water is cleaned substantially under gasifying pressure in a pressure filter, avoids flash evaporation of the residual quenching water into the vacuum area, with vapour cooling and a subsequent increase in pressure and reheating.
摘要:
A gas flow monitor is provided, in which a defined range of the closing or nominal flow can be set without engaging functional elements. Furthermore, the original closing or nominal flow can be adjusted or amended, even outside the manufacturing plant. The gas flow monitor consists of a gas-tight housing (1) which comprises an inner valve seat (5) for a closing member (9) which is displaceable within the housing (1) and is guided in a sleeve (6) in a longitudinally displaceable manner by a pin (7) and is held in the open position against the flow direction by the force of a closing spring (11). The housing (1) is connected on the inlet side to a tubular insert (13), the inner contour (14) of which determines the flow profile up to the valve seat (5).
摘要:
A method and an apparatus for gasifying combustible dusts in an entrained flow gasifier with several gasification burners. Each gasification burner is associated with one or a plurality of lock hopper and dosing systems having a plurality of supply flows. This has the advantage that the burners will continue to operate in the event of a failure of one supply flow.
摘要:
A method and device for cooling hot crude gas and slag from entrained flow gasification of liquid and solid combustibles at crude gas temperatures ranging from 1,200 to 1,800° C. and at pressures of up to 80 bar in a cooling chamber disposed downstream of the gasification reactor by injecting water. The cooling water is distributed, with a first portion being finely dispersed into to cooling chamber and a second portion being fed at the bottom into an annular gap provided between the pressure-carrying tank wall and an incorporated metal apron for protecting said pressure-carrying tank wall. The second portion of the cooling water flows upward in the annular gap and trickles down the inner side of the metal apron in the form of a water film.
摘要:
While ensuring technical safety and a short start-up time the invention permits the operation of autothermic partial oxidation of fuels processed into pulverized fuel such as lignite and bituminous coals, petroleum cokes, solid grindable carbon-containing residues, as well as solid-liquid suspensions or slurries, with a gasification agent containing oxygen at operating pressures of up to 8 MPa (80 bar). The selective configuration of the fail-safe monitoring of the gasification process only the supply of the main fuel is cut off. Through the continued operation of the pilot and ignition burner the reactor is kept at operating pressure and after the fault has been rectified fuel gasification can be restarted with the pilot and ignition burner without a complicated placement and pulling of a starter burner and subsequent pressurization of the reactors.

A compressed air filter and a filter element which is for separating foreign bodies from a compressed air stream and which has an element lower portion, an element upper portion which has a neck portion which forms a first flow channel and a collar portion which is constructed so as to extend at least partially around the neck portion and which is connected to the neck portion so as to form a second flow channel, and a filter medium which is sealingly connected to the element lower portion and the element upper portion in order to form a gas flow path between the first flow channel and the second flow channel through the filter medium, the collar portion having an abutment face, which is provided at least partially at the outer periphery and which tapers in the direction of the element lower portion, in order to receive an associated sealing ring in such a manner that a force which acts substantially axially on the sealing ring from the direction of the element lower portion brings about radial expansion of the sealing ring along the abutment face.
