摘要:
A hydrojet cleaning device (1) for cleaning the interior of a curved or coiled tubular device comprising a flexible hose (3) having one end connectable to a supply of pressurized water, and one end provided with a jet nozzle (5). The flexible hose is provided with a plurality of circumferential spacers (6) distributed over at least a section of the length of the hose. The spacers can for example comprise pulleys (11). Method of cleaning a coiled tubular line, such as a spiralled heat exchanger using such a hydrojet cleaning device. The distance between the spacers may, e.g., be such that the section of the hose between the spacers is entirely spaced from the interior wall of the tubular line wall over its full length.
摘要:
A gasification reactor comprising a pressure vessel encasing a gasifier. Strain gauges are provided in the space between the gasifier and the pressure vessel on one or more parts loaded by weight of slag within the gasifier, e.g., at the exterior surface of the gasifier wall and/or coolant supply lines. Formation of slag deposits and/or pressure within the gasifier is monitored by measuring strain development in parts exposed to stress induced by weight of the slag deposits or induced by internal pressure, respectively.

Process to cool hot gas by passing the hot gas through a tube having a main tubular part and an upstream tubular part, wherein (i) the exterior of main tubular part is cooled by an evaporating liquid cooling medium flowing freely around said tube, (ii) the upstream tubular part is cooled by passing fresh liquid cooling medium and a defined part of the liquid cooling medium of activity (i) along the exterior of the upstream end of the tube and (iii) wherein the mixture of fresh cooling medium and the defined part of the liquid medium after being used to cool the upstream tubular part is used in activity (i) as cooling medium.
摘要:
A gasification reactor including a gasifier having a tubular gastight wall with a discharge channel or dip tube at its lower end leading into a lower slag collection bath. The gastight wall and the slag collection bath are arranged within a pressure vessel. An annular space between the pressure vessel and the gasifier with the discharge channel is separated in a high pressure top section and a low pressure lower section by a sealing arrangement having a damper. The damper can for instance be a hydraulic lock, or a lower seal at a distance below an upper seal.

A gasification reactor including a gasifier with a tubular gastight wall arranged within a pressure vessel. The tubular gastight wall is provided with one or more pressure relief passages sealed by a rupture element. The pressure relief passages can be provided with a cooled section, such as a double walled section confining a coolant channel.
