    摘要: A low or no pollution power generation system is provided. The system has an air separator to collect oxygen. A gas generator is provided with inputs for the oxygen and a hydrocarbon fuel. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide. Water or other diluents are also delivered into the gas generator to control temperature of the combustion products. The combustion products are then expanded through at least one turbine or other expander to deliver output power. The combustion products are then passed through a separator where the steam is condensed. A portion of the water is discharged and the remainder is routed back to the gas generator as diluent. The carbon dioxide can be conditioned for sequestration. The system can be optimized by adding multiple expanders, reheaters and water diluent preheaters, and by preheating air for an ion transfer membrane oxygen separation.

    摘要: The S cycle electric power system embodies a separation condensation unit, a Rankine cycle and the S cycle including coal gasification. Coal, oxygen and steam are converted into high temperature and pressure fuel gas in a coal gasifier. The fuel gas is first utilized to heat recycled carbon dioxide and steam, then to drive a compressor turbine group to produce power. In a main gas turbine group, the fuel gas is burned in the recycled carbon dioxide. Three main turbines are operated at three different pressure levels. The exhaust of the third turbine is employed to heat the recycled carbon dioxide from a 6-stage compressor with intercooling, and to produce steam. Part of the steam goes to coal gasification. The rest of the steam generates power by expansion in a steam turbine. An integrated separation condensation unit produces pure oxygen on site, and captures carbon dioxide formed in fuel combustion. The system has high energy efficiency and zero pollutant emissions including carbon dioxide.
