    摘要: A closed loop oxy-fuel combustion power generation cycle is disclosed. The closed cycle has a gas generator which combusts oxygen with a hydrocarbon fuel to produce a drive gas mixture of steam and carbon dioxide that drives a turbine directly with the drive gas mixture. The drive gas mixture then enters a condenser where carbon dioxide is removed and water is recirculated to a heat exchanger where heat is transferred from the drive gas mixture to the water, to produce high pressure steam. This high pressure steam acts as a separate drive gas for a steam turbine. This steam is only indirectly heated by the gas generator through the heat exchanger, such that the cycle includes both direct and indirect heating of working fluids. Water/steam downstream from the steam turbine is then routed back to the gas generator or downstream of the gas generator to close the cycle.

    摘要: The power plant combusts a hydrocarbon fuel with oxygen to produce high temperature high pressure products of combustion. These products of combustion are routed through an expander to generate power. The products of combustion are substantially free of oxides of nitrogen because the oxidizer is oxygen rather than air. To achieve fast starting, oxygen, fuel and water diluent are preferably stored in quantities sufficient to allow the power plant to operate from these stored consumables. The fuel can be a gaseous or liquid fuel. The oxygen is preferably stored as liquid and routed through a vaporizer before combustion in a gas generator along with the hydrocarbon fuel. In one embodiment, the vaporizer gasifies the oxygen by absorption of heat from air before the air is routed into a separate heat engine, such as a gas turbine. The gas turbine thus operates on cooled air and has its power output increased.

    摘要: A system is provided for hydrogen production from a hydrogen and carbon containing fuel combusted within an oxyfuel combustor. The oxyfuel combustor combusts hydrogen and carbon containing fuel with oxygen at a non-stoichiometric ratio, typically fuel rich. In such an operating mode, products of combustion include steam, carbon dioxide, carbon monoxide and hydrogen. These products of combustion are then passed through a hydrogen separator where hydrogen is separated. Remaining products of combustion can be optionally combusted at a stoichiometric ratio with oxygen in a second oxyfuel combustor discharging substantially only steam and carbon dioxide. A turbine can be provided downstream from the gas generator to produce power and eliminate carbon monoxide from the system. The system can be operated in a second mode where the gas generator combusts the fuel with oxygen at a stoichiometric ratio to maximize electric power generation without hydrogen production at periods of peak electric power demand.

    摘要: A semi-closed combined cycle power system is provided which can also convert an open combined cycle gas turbine into a non-polluting zero emissions power system. The exhaust is not emitted into the atmosphere as with typical open combined cycles, but rather is routed to a divider. The divider splits the exhaust into either a return duct or a separation duct. The return duct routes a portion of the exhaust back to the compressor. Before reaching the compressor, an oxygen duct adds additional oxygen to the exhaust to form a gas mixture which includes and steam from the exhaust and oxygen from the oxygen duct. This gas mixture has characteristics which mimic those of air, so that the compressor need not be modified to effectively compress the gas mixture.

    摘要: A low or no pollution engine is provided for delivering power for vehicles or other power applications. The engine has an air inlet which collects air from a surrounding environment. At least a portion of the nitrogen in the air is removed using a technique such as liquefaction, pressure swing adsorption or membrane based air separation. The remaining air is primarily oxygen, which is then compressed and routed to a gas generator. The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen containing fuel, such as hydrogen or methane. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. Water is also delivered into the gas generator to control a temperature of the combustion products. The combustion products are then expanded through a power generating device, such as a turbine or piston expander to deliver output power for operation of a vehicle or other power uses. The combustion products, steam and, with carbon containing fuels, carbon dioxide, are then passed through a condenser where the steam is condensed and the carbon dioxide is collected or discharged. A portion of the water is discharged into the surrounding environment and the remainder is routed back to the gas generator.

    摘要: This disclosure is the use of high efficiency turbomachinery designs to achieve high efficiency thermodynamic cycles. The high efficiency thermodynamic cycles are referred to as the Modified Ericsson cycles, an expansion of the regenerative Brayton cycle. A Modified Ericsson cycle can include 2,3,4, or more stages (number of intercooling and heat/reheat cycles between stages) that achieve higher efficiencies and power density (net output power/cycle weight flow rate) than those of regenerative and nonregenerative Brayton cycles. Also included is a high temperature tip-turbine driven compressor design for Brayton, Modified Ericsson and other power/refrigeration cycles.

    摘要: A fuel combustion power generation system is provided operating as a closed loop Rankine cycle and with zero atmospheric emissions. The fuel is combusted with oxygen in a combustor to generate high temperature products of combustion. The products of combustion are routed to a first side of a heat exchanger. A second side of the heat exchanger has a working fluid of the closed loop Rankine cycle passed therethrough to boil the working fluid into a gas. The working fluid is then expanded, condensed back to a liquid and pumped back to high pressure for return to the heat exchanger the products of combustion enter a condenser, where gases are collected and liquids recirculated or released. The products of combustion can be expanded upstream of the heat exchanger. The fuel can be a gaseous fuel or a solid or liquid fuel, such as coal or biomass, with gasification before combustion.

    摘要: A reheat heat exchanger is provided particularly for use in Rankine cycle power generation systems. The reheat heat exchanger includes a high pressure path between a high pressure inlet and a high pressure outlet. The reheat heat exchanger also includes a low pressure path between a low pressure inlet and a low pressure outlet. The two paths are in heat transfer relationship. In a typical power generation system utilizing the reheat heat exchanger, the high pressure inlet is located downstream from a source of high temperature high pressure working fluid. An expander is located downstream from the high pressure outlet and upstream from the low pressure inlet. A second expander is typically provided downstream from the low pressure outlet. The reheat heat exchanger beneficially enhances the efficiency of power generation systems, particularly those which utilize expanders having inlet temperatures limited to below that produced by the source of working fluid.
