摘要： This patent of invention is related to a process and a furnace developed for production of charcoal with recovery of gases, tar and pyroligneous extract. The unity system is composed by a metallic furnace, a loading platform, a carbonization platform and unloading platform. For continuous generation of gases, the process operates with multiple carbonization platforms and one or more furnaces for carbonization platform. The furnace is provided with air inputs in strategic side points and mechanism for relieving pressure. The carbonization system is composed by an exhauster, special pipes for conducting the gases, and devices for the recovery of condensable. The gases generated in the process are directed to a burner, a gasifier or directly in a boiler to generate thermal and/or electrical energy. The technology presents, exclusively, a gravimetric yield in fuel gas superior to 60% and a productivity on charcoal above 800 kg/h, so that each operating cycle of the furnace takes less than 5 hours. The coal is discharged hot, after carbonization and loaded on wooden billets immediately after unloading. The process combines technical, economic, operational, and environmentally viable solutions.

摘要： In an energy conversion method and a thermal power plant for converting heat into mechanical or electric energy using a working medium, a vapor state in the working medium is generated at a first pressure in a steam generator. The vaporized working medium is expanded to a lower second pressure in a steam expanding device. An energy obtained by the expansion process is discharged. The expansion of the steam state is carried out using a saturation line of the working medium. The working medium is thereby separated into a non-condensed portion and a condensed portion in a separating device. The non-condensed portion is then compressed into a compressed non-condensed portion in a compressor. The compressed non-condensed portion is cooled and condensed into a compressed condensed portion. The compressed condensed portion and the initially condensed portion are then heated, and both portions are returned to the steam generator together.

摘要： Disclosed herein is a hybrid power generation system using a supercritical CO2 cycle, which includes a first working fluid circuit configured to produce electric power by a first working fluid heated in a boiler, and a second working fluid circuit configured to produce electric power by a second working fluid, and the first and second working fluid circuits share the boiler. The hybrid power generation system can remove an air preheater of a thermal power generation system and separate heat exchange units for exhaust gas and air after combustion, so as to utilize the heat exchange units as a heat source and a cooling source in a supercritical CO2 cycle. Consequently, it is possible to improve power generation efficiency by recovering the leakage loss of the air preheater.
