Provided is a boiler plant including a carbon dioxide capture system. The carbon dioxide capture system has an absorbing-liquid regeneration device and an absorber. The absorbing-liquid regeneration device includes a regenerator, a first circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, and a second circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, a heat exchanger, a heater, and a switcher. The heat exchanger heats the absorbing liquid by exchanging heat between the absorbing liquid flowing through the first circulation line and steam from the boiler. The heater heats the absorbing liquid flowing in the second circulation line. The switcher switches between a first heating state in which the absorbing liquid flows in the first circulation line and a second heating state in which the absorbing liquid flows in the second circulation line.

Steam generators in power plants exchange energy from a primary medium to a secondary medium for energy extraction. Steam generators include one or more primary conduits and one or more secondary conduits. The conduits do not intermix the mediums and may thus discriminate among different fluid sources and destinations. One conduit may boil feedwater while another reheats steam for use in lower and higher-pressure turbines, respectively. Valves and other selectors divert steam and/or water into the steam generator or to other turbines or the environment for load balancing and other operational characteristics. Conduits circulate around an interior perimeter of the steam generator immersed in the primary medium and may have different cross-sections, radii, and internal structures depending on contained. A water conduit may have less flow area and a tighter coil radius. A steam conduit may include a swirler and rivulet stopper to intermix water in any steam flow.

A reaction turbine operates on the heat released from the condensation of steam, combined with inherent steam pressure and temperature heads. A series of rotors, each containing multiple curved internal channels, provide compressive boosts between successive stages, while avoiding excessive self-compression. Compressive effects and shock waves generated within these channels provide high levels of condensation, thereby releasing immense amounts of heat. The resulting hot vapor and condensate droplets are then ejected tangentially at the periphery of the rotors to generate thrust. The exhaust steam from the last stage is then compressed and returned to the engine inlet to be mixed with the incoming fresh steam, thereby efficiently completing the system cycle without the need of large cooling towers for condensation.

During a drilling operation, heat generated by drilling fluid flowing from a borehole, exhaust from an engine, and/or fluid from an engine's water (or other fluid) jacket, for example, may be utilized by corresponding heat exchangers to facilitate heat transfer to a working fluid. The heated working fluid may cause an ORC unit to generate electrical power.
