WebIn high-temperature oxy-fuel combustion processes, fuel and oxygen are mixed at the burner undiluted with recycled flue gas, except to motivate coal for coal-fired systems. This process can result in a high flame temperature (>4,500°F), which enhances heat transfer in the radiant zone of the boiler. Any combustion at high temperatures in atmospheric air, which is 78 percent nitrogen, will also create small amounts of several nitrogen oxides, commonly referred to as NOx, since the combustion of nitrogen is thermodynamically favored at high, but not low temperatures. See more Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a … See more Stoichiometric combustion of a hydrocarbon in oxygen Generally, the chemical equation for stoichiometric combustion of a hydrocarbon in oxygen is: where $${\displaystyle z=x+{\frac {y}{4}}}$$ See more Assuming perfect combustion conditions, such as complete combustion under adiabatic conditions (i.e., no heat loss or gain), the adiabatic combustion temperature can be … See more Complete and incomplete Complete In complete combustion, the reactant burns in oxygen and produces a limited number of products.
