摘要： Disclosed is a staged-air burner device capable of high energy efficiency, high flame stability, combusting multiple readily switchable fuels ranging from pure hydrogen, to any hydrogen/methane mixture, to pure methane, and generating a low level of NOx. The burner device can include: a primary air chamber receiving a primary air and a flue gas; a burner tube capable of receiving a fuel jet and drawing in the air-flue gas mixture from the primary air chamber; a burner tip discharging the fuel-air-flue gas mixture formed in the burner tube to a first combustion zone and a second combustion zone via center orifices and side orifices on the burner tip, respectively; and a staged air chamber receiving staged air and discharging it via staged air ports into a third combustion zone. Combustion of the fuel occurs in at least one of the first, second, and third combustion zones.

摘要： Oxygen carriers for chemical looping and scalable methods of preparation thereof. Wet impregnation of active metal precursors into porous substrates, together with selective adsorption of the precursors on the pore surfaces, enables transition metal oxides derived from the precursors to disperse throughout the substrate, even at the nanoscale, without increased sintering or agglomeration, thereby forming oxygen carriers suitable for chemical looping. The porous substrate can be an oxide, for example SiO2. The oxygen carriers can comprise relatively large oxide loadings of over about 20 wt. % and exhibit high reactivity over many regeneration cycles with substantially no loss in oxygen transport capacity or decrease in kinetics. The use of multiple transition metal oxides, for example NiO in addition to CuO, can greatly enhance chemical looping performance.

摘要： A combustion system includes a fuel and oxidant source, a first distal flame holder body, a second distal flame holder body, and a thermal load. The fuel and oxidant source outputs fuel and oxidant. The first and second distal flame holder bodies simultaneously or alternately hold combustion reaction portions of the fuel and oxidant and/or of combustion products. The thermal load receives thermal energy from the first and second combustion reaction portions.

摘要： A modular burner system includes a nipple elongated along an axis and a plurality of jets connected to the nipple. The jets are spaced from each other along the axis. Each jet connected to the nipple has a jet axis and is elongated from the nipple along the jet axis. Each jet connected to the nipple has an exit on the jet axis spaced from the nipple to release fuel to fuel a flame at the exit. The jet axis of at least one of the jets connected to the nipple is at a first angle relative to the axis and the jet axis of at least one of the jets connected to the nipple is at a second angle relative to the axis different than the first angle.

摘要： A system and method uses a combustor and gasifier to burn a primary dirty fuel, such as waste materials or high-polluting fossil fuels, and a secondary low-polluting fuel, such as biomass fuels, for co-generation of electricity while reducing harmful emissions. The primary fuel is burned at least partially through the use of an improved burner tube. Dirty exhaust from a combustor is scrubbed by a gasifier by reforming the combustors exhaust gases into a clean-burning producer gas (syn-gas). The secondary fuel and oxygen are added to the dirty exhaust in the gasifier to create gas, char and ash. The gas powers an engine or turbine that turns a generator, or a boiler, Stirling engine, or Organic Rankine Cycle power plant, and releases a cleaner exhaust.
