Abstract: Here is described a process to transform energy in chemical form in fuels into electric power through a thermal process. It combines advantages of the traditional internal combustion engine and the steam engine by producing supercritical combustion to allow direct mixture of combustion gases with additional working fluid to cool the mixture to operational conditions. The process allows the control of the inlet temperature of the turbine or expander and makes direct heat exchange by mixing working fluids. The combustion gases are completely used as working fluid in contrast to steam generator. The process improves the efficiency compared to combined cycle or traditional supercritical plants.

Abstract: A pressurized internal circulating fluidized-bed boiler is incorporated in a combined-cycle electric generating system in which a fuel such as coal, petro coke or the like is combusted in a pressurized fluidized bed and an exhaust gas produced by the combusted fuel is introduced into a gas turbine. The pressurized internal circulating fluidized-bed boiler includes a pressure vessel, a combustor disposed in the pressure vessel and a main fluidized bed combustion chamber provided with an air diffusion device. A thermal energy recovery chamber is partitioned from the main combustion chamber by an inclined partition wall. A fluidized medium flows into and out of the main combustion chamber and the thermal energy recovery chamber. A free board is provided integrally above the main combustion chamber and the thermal energy recovery chamber so that combustion gas from the main combustion chamber and the thermal energy recovery chamber is mixed in the free board.

Abstract: A supercritical hydrothermal combustion device comprises a main enclosure and a top cap. A partition is mounted in the main enclosure and divides the interior of the main enclosure into a main combustion space and a mixing space. The top cap is provided with a primary fuel inlet, an oxidant inlet and a secondary fuel inlet. A high-temperature ignition bar sleeve, having a high-temperature ignition bar arranged therein, is disposed in the top cap. A combustion sleeve, having a stable combustion space formed therein, is mounted at a bottom of the top cap, and has a top communicated with the high-temperature ignition bar sleeve and the oxidant inlet, as well as a bottom communicated with the main combustion space. The secondary fuel inlet and a secondary oxidant inlet are communicated with the main combustion space. Supercritical hydrothermal combustion is realized to generate a hybrid thermal fluid or treat organic wastes.
