A combustion simulation system is provided. The system receives data representing a fluid flow. The data includes a plurality of combustion precursors, including at least one arbitrary combustion precursor that may not correspond to a physically realizable material. The system simulates a chemical combustion reaction involving the plurality of combustion precursors and generating combustion byproducts. The system determines a change in temperature and a molar mass of the combustion byproducts due to the chemical reaction, and determines a divergence of the combustion byproducts based on a combination of the change in the temperature and the change in molar mass. The system then generates one or more data structures of the simulated combustion based on at least a portion of the fluid flow.

The current invention discloses a method and apparatus for production of hot water or steam in a 4-pass firetube boiler. A waste heat stream is passed through the first and second passes of the boiler, and then routed into a furnace tube (which is the third pass of the boiler) to help suppress the flame temperature and NOx emissions from the burner. The flue gas from the third pass is then passed through the fourth pass of the boiler to transfer the heat energy to the water in the boiler.

A burner includes a distal flame holder, first and second fuel nozzles, a fuel and oxidant source, and a mixing tube disposed upstream from the distal flame holder. Fuel emitted from the first fuel nozzle mixes with oxidant from the oxidant source to form a fuel and oxidant mixture to support combustion in the distal flame holder. A non-reactive fluid source such as recirculated flue gas provides a non-reactive fluid for dilution of the fuel and oxidant mixture to prevent flashback.
