摘要： A mass stream of a dusty solid fuel is conveyed pneumatically through a supply pipe leading from a dosing container to a gasification reactor. A gas admixing device is connected in series with the supply pipe near the outlet of the container for injecting an auxiliary gas into the mass stream. The parameters of the mass stream are measured before and after the mixing device and applied to a computer which determines the amount of the injected gas and the value of the mass stream. In this manner, the arrangement for measuring the gas stream can operate continuously and independently from the technology of feeding the dust to the supply pipe and provides quantitatively correct measuring values at all dust concentrations and system pressures. The method eliminates complicated velocity measurements in two-phase dust streams and does not necessitate any measuring probes which project into the conveying channel and obstruct the flow.

摘要： A method and device for metering and feeding pulverized fuels under pressure into gasification reactors, with the pulverized fuel being supplied alternately from an operational bunker through pressurized sluices to a metering tank, in the bottom of which a dense fluidized bed is formed by introducing fluidizing gas through a turbulence plate, with transport pipes immersed in the fluidized bed horizontally or vertically, by which the fluidized fuel is fed continuously through burners to a pressurized gasification reactor. By feeding in auxiliary gas in the immediate vicinity of the transport line inlet into the metering tank or the transport lines, the pressure differential between the metering tank and the gasification reactor is controlled and is utilized as a control parameter for pulverized fuel transport.

The cooling shield has at its upper end a gap communicating with the second interspace and the lower end of the reactor is provided with a pressure releasing conduit communicating with the bottom of the second interspace so that when the gas generating process is interrupted and the conduit is opened the pressurized gas escapes from the reactor chamber through the upper gap and flows through the major part of the second interspace to be cooled down before the discharge from the connecting conduit.

摘要： A method of adjusting the mass stream and flow density of a finely divided, fine-grained solid fuel is described. The method uses a dosing container having a fluidized bed at its bottom part and into which the solid fuel is charged above the fluidized bed. A fluidizing gas is adjustably fed to the bottom part of the container and a compensation gas is fed to the upper part of the latter. Mass stream parameters and density are measured in the discharge or supply pipe communicating with the fluidizing bed and the required weight of flow of the fluidizing gas is computed by a computer. In this manner, the regulation of the mass stream is effected by adjusting the loose density of the charge of the dusty material in the container.

摘要： The burner is formed of a tubular housing including a central tubular passage and a boundary annular passage for feeding into the gasification reactor under high speed a carburation medium such as oxygen or steam. At least three intermediate channels of coaxial annular sections are symmetrically arranged about the central channel and each communicates with a separate inlet conduit for feeding a mixture of powderized fuel with a carrier gas. The transition between the annular intermediate channel and the tubular inlet conduits is made such that the varying outline of the cross-section encloses the same area as the tubular inlet conduit or the annular section intermediate channel. The central tubular channel and the boundary annular channel for feeding the carburation fluid is configurated so as to divert one stream of the carburation fluid at an angle of about 45.degree. toward the axially directed jet of the powderized fuel mixture.

摘要： Disclosed is a burner for oxidant gasification of pulverized fuels under high pressures, e.g. 80 bar, and temperatures, e.g. 1200 to 1900° C., in reactors with liquid slag removal for oxygen gasification. The individual pulverized coal supply tubes in the burner are inclined toward the burner axis in the direction of the burner mouth, are implemented equiareally from the burner inlet up to the burner outlet, and end at the burner mouth adjacent to the oxidant outlet. Owing to the pulverized fuel feeding elements being implemented right up to the burner mouth and the instantaneous entry of the pulverized coal into the rotating oxygen stream there is no longer any areal discontinuity at the dust outlet, since here the pulverized coal stream is immediately sucked into the oxidant stream. At the outlet of the media the individual pulverized coal streams merge into a single rotating pulverized coal/oxygen stream, thereby achieving an even flame spread and stabilization.
