Hydrogen gas compression systems that each include a multistage centrifugal compressor in which each stage has an inlet-to-outlet pressure rise ratio of about 1.20 or greater. In one embodiment, the multistage compressor includes six high-speed centrifugal compressors driven at a speed of about 60,000 rpm. The compressor has an output of more than 200,000 kg/day at a pressure of more than 1,000 psig. The compressors for the compression stages are distributed on both sides of a common gear-box, which has gearing that allows axial thrusts from the compressors to be handled effectively. Each stage's compressor has a unique impeller, which is secured to a support shaft using a tension-rod-based attachment system. In another embodiment, the multistage compressor is driven by a combustion turbine and one or more intercoolers are provided between compression stages. Each intercooler is cooled by coolant from an absorption chiller utilizing exhaust gas from the combustion turbine.

Compressor Surge Control System and Method

Номер: US20120014812A1
Автор: Barry Earl Dick, Paul Musgrave Blaiklock
Принадлежит: TMEIC Corp

A system and method for controlling gas surges in compressors powered by electric motors. An adjustable speed drive (ASD) incorporating a microprocessor powered by a three-phase source of electricity controls the electric motor which drives the compressor. A bypass valve is inserted between the gas input of the compressor and the gas discharge. The bypass valve opens in response to signals from the ASD which detects gas surges by analyzing a stored surge map which plots a surge line and a related discretionary control line based on the power and speed of the motor. When the operating point of the motor crosses the control line, the ASD causes the bypass valve to open.

In particular suitable for very high density process gases such as super critical CO2, R134a, R245fa, etc. The turboalternator comprises two separate machines, specifically, a turbine device and an alternator device operatively connected together by a coupling shaft. The rotating shaft assemblies for each machines on the turbine side and the alternator side are supported by hydrodynamic foil gas bearings. The foil gas bearings use process gas at the turbine side, enabling high-pressure operation (˜3000 psia) and thrust load balancing. At the alternator side, cooling fluid is used in the foil gas bearings, enabling high-speed (˜40,000 rpm), low-windage, oil-free operation with closed-loop shaft cooling.

APPARATUS FOR RECOVERING KINETIC ENERGY RELEASED DURING LANDING OF AN AIRCRAFT AFTER CONTACT WITH THE GROUND, AND METHOD

Номер: US20130087654A1
Автор: Seibt Christian

At least one energy storage system is provided for receiving and releasing at least a part of the converted kinetic energy from a landing aircraft. The system has a high degree of multiple utilisation and enables, for example, manoeuvring of a landed aircraft on the taxiway independently of the engines, where the aircraft is substantially moved with the braking energy recovered during the landing process. As a result of the main engines no longer being required for manoeuvring, there is a considerable potential for saving energy and the use of motor-operated tow vehicles is eliminated. The apparatus also contributes in the sense of a “green” and economical technology to saving aircraft fuel and better fulfils future requirements of airports, particularly with a view to noise and pollutant reduction. In addition, the invention has as its subject matter a method for recovering braking energy of an aircraft. 1. An apparatus for recovering the kinetic energy released during landing of an aircraft after contact with the ground , for ground and/or flight operation comprising at least one energy converter for conversion of the kinetic energy into another energy form , where the energy converter is located in the area of the nose landing gear and/or in the area of the main landing gear of the aircraft , characterised in that at least one energy storage system is provided for receiving and releasing at least a part of the converted kinetic energy.212.

The interior passage is located between an annular inner wall, and an outer wall extending about the inner wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The inner wall is eccentric with respect to the outer wall so that the cross-sectional area of the interior passage varies about the bore. The variation in the cross-sectional area of the interior passage can control the direction in which air is emitted from around the air outlet to reduce turbulence in the air flow generated by the fan assembly.

The ceiling mounted ventilation fan with illumination employs a configuration in which a second opening for guiding light from an illumination unit into the room is formed in a lower part of a main housing and in which a air inlet on a fan casing of a fan unit is provided so as to open toward upper part of the main housing. Thus the air inlet of the fan unit opens in a direction opposite to the second opening communicating with inside of the room. As a result, sounds such as operation noises from the fan unit that are transmitted to outside of the fan unit chiefly through the air inlet can be made to resist being transmitted through the second opening into the room, so that the noises can be reduced.
