The present disclosure relates to systems and methods that are useful for controlling one or more aspects of a power production plant. More particularly, the disclosure relates to power production plants and methods of carrying out a power production method utilizing different fuel chemistries. Combustion of the different fuel mixtures can be controlled so that a defined set of combustion characteristics remains substantially constant across a range of different fuel chemistries.

A combustion simulation system is provided. The combustion simulation system can be performed using a computing device operated by a computer user or artist. The computer-implemented method of simulating a combustion process includes receiving a set of data representing a fluid flow. The fluid flow can include combustion precursors. The method includes simulating a chemical reaction representing simulated combustion of these precursors generating combustion byproducts. The method can include determining a change in temperature of the combustion byproducts due to the chemical reaction, determining a change in molar mass of the combustion byproducts due to the chemical reaction, determining a divergence of the combustion byproducts based on a combination of the change in the temperature and the change in molar mass, and generating data structures of the simulated combustion based on values of the fluid flow.

The field of present invention generally relates to furnaces that combine fuel production with both thermal and electrical energy production. They also are capable of using carbon emission as part of the production process. More particularly, the present invention produces a combustible gas that, within the internal workings of the present invention, can efficiently be burned at relatively lower temperatures and pressures without the production of high levels of pollutants. Further, the present invention can receive what are ordinarily wasteful carbon emissions for use in the production of more desirable outputs. The foregoing characteristics, along with the limited size of the elements needed to practice the present invention, make it conducive for use as and in connection with, among other things, residential furnaces and other heating systems, including, for example, heat exchangers and residential hot water tanks. In short, the present invention involves the production of a combustible fuel gas, and of thermal and electric energy, and the productive use of carbon emissions. This production is accomplished through the interconnected use of water electrolysis, catalysts, storage means, regulation, and mean of reusing materials to increase production efficiencies.

Methods and combustion devices for reducing NOx formation upon combusting oxidant with fuel to form products of combustion are provided. Such methods and device may involve mixing at least first portions of at least two fluids selected from the group of oxidant, fuel and recirculated products of combustion in at least one first conduit to form a first mixture. The first mixture is subsequently supplied to a plurality of second conduits each in direct fluid communication with the first conduit. Motive energy is utilized to aspirate at least second portions of one or more fluids selected from the group of oxidant, fuel and recirculated products of combustion in at least one second conduit to form a combustible mixture that can be subsequently burned. In one embodiment, the motive energy may be provided or result from the first mixture.

A feedstock reactor having a reaction chamber connected to multiple combustors is operated such that, for each reaction cycle in a sequence of reaction cycles, one or more combustors of the multiple combustors are loaded with a combustible gas mixture, and/or the combustible gas mixture in a number of the multiple combustors is combusted, thereby producing combustion products that flow into the reaction chamber. For at least a first reaction cycle and a second reaction cycle in the sequence of reaction cycles, the second reaction cycle occurring after the first reaction cycle, the number of the combustors in which the combustible gas mixture is combusted is greater in the second reaction cycle than in the first reaction cycle, and/or an equivalence ratio of the combustible gas mixture loaded into the one or more combustors is higher in the second reaction cycle than in the first reaction cycle.

A pyrolysis system for conducting a hydrocarbon pyrolysis reaction and related systems and methods are disclosed herein. For example, a pyrolysis reactor according to the present disclosure can include a first chamber, a second chamber coaxial with and positioned within the first chamber, and a burner positioned at least partially within the second chamber. The burner can include a main body as well as a distal end region. The main body includes a fuel input channel and an air input channel. The distal end region includes a first orifice fluidly coupled to the fuel input channel and a second orifice fluidly coupled to the air input channel. The first orifice and the second orifice are positioned to create a mixture of the combustion fuel and oxygen downstream from the distal end region. The burner can also include an ignition component positioned to ignite the mixture.

Processes and apparatuses for heating process fluid in a furnace. Fuel to the furnace is either hydrocarbons or hydrogen. The fuels may be sent to different furnaces or be sent at different times to the same furnace. Furnaces that are configured to receive both types of fuels may have different exhaust paths. An exhaust path for hydrocarbon fuel flue gas includes a carbon capture process zone.
