Abstract:
The nozzle is used for the processing of plastics. Its usage reduces the injection losses. The nozzle consists of a steel cylinder (10) with a flange (11). In the lower part of cylinder (10) concentric cavity (12) is machined, and at its other end there are two plane surfaces (13) inclined to its longitudinal axis towards each other at an angle of from 70 to 140 deg.C. In each surface (13) an orientated groove (14) is bored. The grooves form an angle of 70-140 deg.C in between, the peak of which is outside the nozzle. 4 claims, 3 figures
Abstract:
Le procédé consiste en la pyrolyse des déchets ménagers par la chaleur de la dissociation moléculaire d'un gaz ou d'un mélange de gaz à une température supérieure à 3000°C obtenue grâce à l'énergie électrique sous forme de plasma, de chauffage inductif ou par pertes dans le dielectrique que constitue le gaz. Une injection de graphite dans le plasma, modifiera l'équilibre atomique et provoquere dès 2000°C, une réaction exothermique considérable. Les températures très élevées seront maintenues dans des limites acceptables par les installations Turbine-Vapeur et Turbine-Gaz-Vapeur par des injections de CO2 et H2 à des endroits bien précis. A un endroit précis du cycle, on pourra extraire H2du gaz de synthèse. Toutes les injections de CO2 et H2O seront telles que les gaz d'échappement de la Turbine-Gaz seront composés de CO2 et H2O dans le rapport: CO2=11/9 H2Oà la température de l'ordre de 770K°. On ajoutera, à un gaz d'échappement, la quantité adéquate de gaz naturel afin d'obtenir à 500K°,
Abstract:
The gasification apparatus for gasification of finely divided combustible material under pressure includes a gasification reactor which produces a crude gas, a quenching pipe and a convection-heated boiler with a boiler housing, all mounted inside a pressurized vessel. A gas flow guiding device is provided above the quenching pipe for conducting a mixed gas flow containing the crude gas and a quenching gas from the quenching pipe into the convection-heated boiler which surrounds the quenching pipe concentrically. A gas outlet device is provided for the gas flow from the convection-heated boiler and from the pressurized vessel. The gasification reactor is supported at its bottom end in the pressurized vessel at anchoring points. The convection-heated surface elements of the convection-heated boiler are supported by the quenching pipe and the boiler housing but in a stress-free manner. A quenching gas inlet device is provided and includes a circumferential gap between an inlet section of the quenching pipe and an adjacent outlet section of the gasification reactor through which a quenching gas is conducted to form, together with the crude gas, the mixed gas flow.
Abstract:
A partial oxidation feed system (10) and a method are provided. The system (10) includes a slag additive slurry feed system (31) configured to combine a slurrying agent (24), a mineral slag additive (22), and a liquid slurrying medium (25) to generate a stabilized mineral slurry (26). The slurrying agent (24) is configured to increase a viscosity of the stabilized mineral slurry (26). The system (10) also includes a partial oxidation system (12) configured to receive the stabilized mineral slurry (26), a feedstock (16), and oxygen (14) into a gasifier reaction chamber (27). The partial oxidation system (12) is configured to partially oxidize the feedstock (16) to produce a gaseous product (18) and a solid product (20).
