Method of stabilizing a combustion process

摘要

In a combustion process, liquid or gaseous residues having little or no calorific value are supplied to a flame in the main combustion chamber in addition to the fuel gas and the air for combustion. Stabilization of the flame and hence a reduction in the emission of nitrogen oxides is achieved by preheating the fuel gas and introducing it into the main combustion chamber at a temperature above its ignition temperature.
