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.

A consumption amount of high-calorific gas such as coke oven gas (COG) during operation of a gas turbine is reduced, halt of the gas turbine due to clogging of a pilot system, a malfunction of a compressor which compresses high-calorific gas is prevented, and reliability of the gas turbine is improved. When operation of the gas turbine ( 11 ) starts, with use of both a first fuel supply system ( 31 ) which supplies a high-calorific fuel for a first nozzle constituting a combustor ( 17 ), and a second fuel supply system ( 32 ) which supplies a low-calorific fuel for a second nozzle constituting the combustor ( 17 ), the high-calorific fuel and the low-calorific fuel are supplied to the combustor ( 17 ), and at a time when the gas turbine ( 11 ) reaches output power which enables continuous operation with only the low-calorific fuel, supply of the high-calorific fuel to the combustor ( 17 ) is shut off, and only the low-calorific fuel is supplied to the combustor ( 17 ).

Engine-load connection strategy

Номер: US20120102911A1

Принадлежит: ICR Turbine Energy Corp USA

A method is disclosed for connecting gas turbine engine gasifier components to a transmission, generator or other load. The interface of an engine gasifier module and a load module is made between one of the gasifier turbo-compressor spools and the free power turbine. This connection is between ducting components. This reduces the precision required to mate an engine module with a load module. In the case of a large vehicle, it is possible to mount an engine skid between the structural frame members of the truck cab, in the traditional engine compartment of the cab or vertically behind the cab of the truck since the engine module can be connected to the truck's transmission module via ducting between a gasifier module components and the free power turbine and ducting between the free power turbine and exhaust or recuperator.

A process for treating a waste feedstock using a gasifier and the gasifier for same. Hot exhaust from an engine travels through a series of hollow heating plates stacked vertically within a gasifier reactor with spaces between each set of successive heating plates forming reaction zones. Each reaction zone is divided into an upper treatment area and a lower treatment area by a rotating disk. Waste material travels from an outer feed spot along the top surface of the rotating disk radially inwardly to a drop area located at the radially innermost portion where it drops to the top surface of the hollow heating plate below. The waste material is then conveyed radially outward to a chute to the next reaction zone or once fully processed to an exit from the reactor. Vapors from the waste material are drawn off each reaction zone through an outlet for further processing.
