A combined-cycle power plant comprises a gas turbine engine for generating exhaust gas, an electric generator driven by the gas turbine engine, a steam generator receiving the exhaust gas to heat water and generate steam, and a duct burner system configured to heat exhaust gas in the steam generator before generating the steam and that comprises a source of hydrogen fuel, a fuel distribution manifold to distribute the hydrogen fuel in a duct of the steam generator, and an igniter to initiate combustion of the hydrogen fuel in the exhaust gas. A method for heating exhaust gas in a steam generator for a combined-cycle power plant comprises directing combustion gas of a gas turbine engine into a duct, introducing hydrogen fuel into the duct, combusting the hydrogen fuel and the combustion gas to generate heated gas, and heating water in the duct with the heated gas to generate steam.

An innovative oxyhydrogen (HHO) burner system including one or more burner systems is provided to eliminate emissions through total combustion. Each burner system includes at least one HHO gas supply and an external natural gas supply, both of which are connected to a gas mixer. A controller regulates the amounts of incoming HHO gas and the natural gas through being mixed. The mixed gas is supplied to each burner assembly with a predetermined pressure and flowrate to generate a flame for the total combustion of the exhaust stream inside the exhaust pipe. With feedback from an exhaust measuring system inside the exhaust pipe adjacent the outlet, the controller can adjust the burner system for optimal operations and achieve total combustion. Thus, by passing the exhaust or gases through a substantial cross-section covered by each flame, emissions can be greatly reduced or eliminated.

A combustion system with surface-less heat energy exchange for efficient heat energy capture and lower pollutant emission, comprising: a first line feeding an oxygen-rich reactive; a second line feeding a hydrogen fuel; a vessel containing feed-water, a combustion enclosure without a bottom wall submersed into the feed water contained in a vessel, the combustion enclosure configured to receive the feed from each of the first and second line and combust a mixture of the two feeds in a pocket formed between an inner top and side walls of the combustion enclosure and a top surface of the feed-water contained in the vessel; and the combustion within the pocket yielding a high temperature and pressure combustion product and by-product directly into the feed-water of the vessel.

The invention relates to a system for treating hydrogen and/or oxygen gas produced by water electrolysis and serving to supply a combustion process, characterised in that it comprises at least one heat exchanger, in which the one or more gases circulate so as to be cooled or heated, said heat exchanger being submerged in a reactive compound through which the one or more gasses pass in turn.

The present invention relates to a method of optimization for continuous combustion systems, which reduces fuel consumption, exhaust emissions and particulate matter. The operating principle is based on the introduction of small amounts of hydrogen in the fuel intake duct of the system, or preferably along the continuous burning chamber, with the aim of optimizing the burning of traditional fuels, improving the parameters of the combustion reaction, the effect of the process in question will increase the temperature of the walls of the chamber, ensuring re-ignition and a more complete combustion and consequently reducing the required fuel flow feed. This optimized combustion will increase the combustion efficiency and reduce its environmental impact.

A hydrogen production system includes: a hydrogen production device connected to an electric power system and configured to produce hydrogen by electrolyzing pure water; an output control unit capable of controlling an amount of power supplied from the electric power system to the hydrogen production device according to request from the electric power system; a first pure water line for supplying pure water to the hydrogen production device; a first adjustment device capable of adjusting an amount of pure water supplied to the hydrogen production device via the first pure water line; and a first control unit configured to control the first adjustment device, based on a power amount signal indicating information on an amount of power supplied from the electric power system to the hydrogen production device.

A continuous reflux reactor and controlled condenser system for thermochemical treatment of plastic and/or elastomeric waste has five zones with different complements. The zones comprises the bottom zone, pyrolysis zone, meeting zone, reflux zone and extraction zone. The reactor uses a reflux zone to increase the production of a light oil in the process. The reflux zone is equipped with some studded tubes that enhances the contact area. Cold molten salt is used as the cooling element of this step. The pyrolysis zone, where the material will be pyrolyzed, has the differential of being equipped with molten salt coils using hot molten salt as the heating element. After the material passes to all zones, the material goes to a cyclone that will condense heavier hydrocarbons present in this step and send the light hydrocarbons to the condensers.

A burner for producing a stabilized flame with an inertisation front upstream from the stabilized flame includes a swirl generator and an inlet device with a passage therethrough. The swirl generator swirls an inert process medium about a swirl axis in a flow direction and one or more openings in the inlet device provide one or more partial mass flows containing combustion educts. The inert process medium inhibits combustion of the combustion educts through the inertisation front to displace the stabilized flame from the one or more openings.
