摘要:
A method for monitoring a combustor comprising: measuring several times a distance between a first wall of the combustor and either a second wall of the combustor or a sensor of the combustor by the sensor, and concluding from a variation in the distances a formation of deposit on the first and/or second wall and/or sensor, and/or a temperature change within the combustor, and/or a pressure change within the combustor.

A system of injecting fuel into the combustion chamber of an engine, including at least two fuel circuits, one permanent flow circuit and one intermittent flow circuit, fuel proportioning and distribution devices for proportioning fuel and distributing fuel between the two circuits and a controller. When an order to fill circuits with fuel after the circuit with intermittent flow has been drained is received, the controller is adapted to control the proportioning and distribution devices to obtain a predetermined fuel flow higher than the flow corresponding to the filling order and to supply the resulting surplus of fuel to the intermittent flow circuit for a predetermined duration.

Process, reactor and burner for the gasification of a hydrocarbon fuel. The burner comprises coaxial channels for the separate supply of an oxidizer gas, a hydrocarbon fuel and a moderator gas. A coaxial channel with the smallest width is bordered by a separating wall with at least one gas exchange. The gas exchange passage can for example be formed by a retracted end of the separating wall and/or by openings in the separating wall.
摘要:
A treatment module for use in an abatement system for process exhaust gases. The treatment module has a centrally located flame wall oxidizer module that cause the process exhaust gases to travel within a cylinder of gas a short distance upon exiting the exhaust conduit before the gases are oxidized. Following oxidation, two coaxial cylinders of water spray flush solid, liquid and water soluble components of the oxidation products from the resulting oxidation products stream into a bottom water reservoir. The first inner water spray cylinder coaxially surrounds the flame wall oxidizer module and flows co-currently with the downward flow of oxidation products. The gaseous oxidation products then turn 180 degrees and pass upward through a second outer water spray cylinder located coaxial to and surrounding the first water spray. Thereafter, the remaining water insoluble gaseous oxidation products exit the treatment module.

The invention relates to a burner, in particular a residual gas burner for a fuel cell system. The burner includes a combustion chamber which is bordered by a supply wall and by a heat exchanger and which is encompassed at the sides by a burner wall. The heat exchanger is a cross-current heat exchanger having a primary path and a secondary path. The supply wall has a burner zone with oxidizer openings for oxidizer gas and with combustion gas openings for combustion gas and a bypass zone with bypass openings for bypass gas. The bypass zone is arranged in a section of the supply wall which is allocated to an area of the heat exchanger adjacent to the primary path and to the secondary path at the inlet end, so that the bypass gas or a bypass gas-burner exhaust gas mixture acts upon this area.
摘要:
A starting injector usable in all flight modes without additional cost or weight. The starting injector includes a dual fuel circuit and an air circuit. An injector for a combustion chamber of a gas turbine includes a dual fuel injection circuit including a starting fuel circuit for ignition and then for all the flight modes, and a main fuel circuit for all the flight modes after starting. The circuits include parallel pipes in a common tube having an axis. The pipe of the starting circuit is substantially in communication with a center of a spherical injector body. At the end, the pipe accommodates an injection manifold coupled to a central channel passing through a central wall of a swirler. The pipe of the main circuit is in communication with an annular channel opposite jet channels. An air circuit is guided between two portions shaped as concentric spheres.
